An ongoing discussion about SAP infrastructure

There is HoP for HANA – HANA on Power T&E program begins

At SAPPHIRE NOW 2014 in Orlando, Bernd Leukert, (member of the SAP Executive Board with global responsibility for development and delivery of all products) made an announcement for which most of the community of IBM Power Systems customers, sellers and integrators have been waiting for a long time.  He announced the testing and evaluation program for HANA on IBM Power Systems (HoP).  As SAP has done with virtually every product they have introduced in the past, they will work with a select group of customers that have the interest, skills, experience and willingness to dedicate the time to thoroughly put a product through its paces to ensure that it will deliver the value necessary to customers, operate efficiently and without error and perform at an acceptable level.  Often, this is called Ramp-up and usually, unless critical problems are found, it is followed by an announcement of General Availability (GA).  During this announcement, Mr. Leukert mentioned that customers are welcome to request a full disclosure of SAP’s plans to support HANA on Power. 


Many people came through our booth, joined us in meetings and used other channels to ask one simple question: “Once HoP reaches GA, why should a customer prefer this solution over one from the plethora of x86 based vendors.  I will boil down this subject into 5 key points: 1) Performance, 2) Reliability, 3) Flexibility, 4) Efficiency and 5) Cost


1)      Performance – HANA, as most know, is an in-memory database.  It replaces complex and cumbersome indexes and aggregates with highly compressed columns of data which can be traversed very quickly (full column scans, in effect) and in ways that don’t have to be considered ahead of time by architects and DBAs.  The speed comes at the cost of memory and can be limited by the bandwidth of the memory subsystem in addition to the throughput and number of processor cores in a system.  IBM recently announced 1 and 2 socket POWER8 systems capable of supporting a maximum of 1TB of memory (with both sockets populated).  A radically faster backplane and up to 128MB of L4 cache (with all memory slots populated) result in a maximum bandwidth of 384GB/s.   This compares to a two socket IvyBridge EX system (with 30 cores) which has a maximum bandwidth of 68GB/s in full RAS mode (85GB/s in the benchmark only, no sane customer would ever run HANA with partial RAS mode).  In other words, the 2-socket Power System can deliver 5.6 times the memory bandwidth.  Not bad, but not the whole story.  High memory throughput without high CPU performance results in a simple shifting of bottlenecks.


Each POWER8 core supports a robust cache hierarchy with twice the L1, L2 and L3 compared to Ivy Bridge systems (in full RAS mode),  up to 8 simultaneous threads (SMT8) and dual SIMD (Single Instruction Multiple Data) pipelines, compared to 2 threads (Hyperthreading) on IvyBridge EX and a single SIMD pipeline.  HANA takes full advantage of lots of cache, threads and SIMD pipelines. 


As HoP is not yet GA, no formal benchmarks are available.  That said, the Power S824 (POWER8, 2 socket with 24 cores, 4U system, Cert # 2014016) running AIX achieved 21,212 Users, 116,727 SAPS on the SD 2-tier benchmark.  Not bad, especially when you consider that the best IvyBridge EX 2-socket , 30-core system SD 2-tier benchmark result to date achieved 12,280 Users, 67,020 SAPS (Cisco UCS B260 M4, Cert # 2014018).  On this benchmark, the Power System delivered almost 73% more performance per systems, 116% more performance per core.  While performance with a conventional DB and app servers cannot be correlated with predicted HANA performance, it is a reasonable measurement to consider relative performance of the two types of systems.


2)      Reliability – IBM Power Systems have a long history of providing mission critical reliability.  As I have written about in previous blog entries, IBM Power Systems have a long history of providing mission critical reliability.  Data analysis companies have evaluated extensive outage data from customers and determined that Power Systems, on average, have experienced up to 60% fewer outages than x86 systems with up to 5 times faster recovery from outages when they do occur.  That said, Intel has made many strides forward in reliability features.  If we were to assume equivalent reliability at the processor core level (Intel claims, not backed up by customer data yet), there are still a whole host of components that can result in outages, not to mention a major difference in the underlying RAS architecture for problem detection and resolution.  As this has been a discussion in previous blog entries, let me instead focus on the new improvements in POWER8 which leap frogs x86 systems.  As mentioned earlier, HANA loves, eats and breathes memory.  So, let’s consider memory reliability.  POWER8 memory cards on these new scale-out systems include features previously available only on Enterprise class systems such as the Power 770.  Specifically, each rank of memory features an inactive chip that is included at no extra cost and can take the place of a failing chip on the fly.  This is in addition to ChipKill (ECC on steroids) or a recovery mechanism across chips, not only within each one.  By comparison, x86 systems may offer ChipKill or even double ChipKill, but to avoid “recovery” after a chip failure, x86 systems would require memory mirroring (available on most high end x86 systems) but this effectively reduces memory capacity by 50% as ALL memory is mirrored.  This means that a 1.5TB, 30-core IvyBridge EX system would only be able to deliver 768GB of memory with similar memory redundancy to POWER8 with a full complement of 1TB of memory. 


Lacking this huge penalty, most customers will stick with non-mirrored memory at a considerably lower reliability level.  But the story does not end there.  POWER8 adds extra protection on the memory bus with built in redundancy and automatic failover in the event of a memory lane failure. 


Taken together, some estimates suggest that POWER8 systems will experience 2.5 to 8 times fewer system outages caused by the memory subsystem than similarly configured x86 systems.   Put another way, if we were to assume that a 1TB x86 system would experience one outage every 10 years (just a random number for comparison purposes,  not based on any actual data), then 10 such systems would result in 1 outage every year based on memory alone.  Maybe not a huge problem for BW systems with scale-out/HA configs, non-mission critical analytics systems or non-prod systems, but could be a big problem for mission critical business suite systems on separate nodes much less larger ones that place multiple SAP components on one node (yes, SAP seems to be envisioning a future of MCOD or Multiple Components on One DB).  Remember, however, that this is just the memory subsystem associated failure and there are many other potential areas of system failure for which Power has its long track record of superior protection and recovery.


3)      Flexibility – POWER has virtualization built in.  It is included by default at the hardware/firmware level (unless one were to remove the PowerVM hypervisor and replace it with PowerKVM, not the intended hypervisor for HANA).  At SAPPHIRE, SAP announced GA support for HANA production on VMware vSphere 5.5.  Just because you CAN do something does not mean that you SHOULD.  You could run across a busy highway without the assistance of lights or overpasses, but most people would consider you crazy to do so.  Likewise, vSphere 5.5 still utilizes the same I/O infrastructure that it has in the past resulting in all I/O writes, having to pass from a VM through its virtual device driver to the memory space of the vSphere hypervisor and then on to the I/O subsystem through another “real” device driver and the same, albeit reverse, path on reads.   If that was not bad enough to dissuade all but the most ardent VMware proponents from placing any large scale transactional DB on VMware, VMware’s own published study shows only 65% scaling on 32 virtual processors, which when extrapolated to 64 or 128 vps shows no incremental benefit at all.   Can you then image an incredibly memory intensive HANA system running with a ton of memory but only being able to utilize 32 threads/16 cores effectively?  Would this break the KPIs for HANA? 


Another area of flexibility comes from configuration options.  We have recommended a TDI approach (Tailored Datacenter Integration: where SAP defines the KPIs for HANA and allows customers to determine how they will satisfy those KPIs.  In other words, if a customer wants to use an LPAR on a POWER7+ or POWER8 system, their choice of storage based on their current standards and install base (e.g. EMC, HDS, NetApp, IBM), an existing network infrastructure, on-board or off-board flash drives, XFS or GPFS, etc., a TDI approach would allow for the flexibility to select the components and configurations that work best for them. 


4)      Efficiency – If running VMware is not a good option, as suggested above, then customers would be forced to employ islands of automation, multiple different HANA implementations on separate servers each with its own dedicated HA and DR servers, ABAP and JAVA app servers on their own systems, probably virtualized, but still separate from the HANA system.  Yes, you might virtualize non-prod, but if you virtualize QA or a stress test system, then you have violated one of the fundamental rules in system architecture, i.e. never utilize a different stack in the critical QA path that is not used in production.


By comparison, Power has no such limitations. Anything can be mixed and matched as desired, with obvious constraints of CPU, Memory and I/O considered, of course.  In other words, customers will have the flexibility to put together anything in almost any combination based on their unique needs.  Higher performance and comprehensive virtualization may result in fewer systems being required since it allows customers to place many different partitions (VMs) together, including HANA, app servers, non-prod and HA, into a single cluster using shared, virtualized resources.  As a result, data center footprint, power, cooling, administration, problem resolution, etc. can all see substantial reductions.


5)      Cost – With the introduction of POWER8 and its Linux only models, IBM entered a new era on pricing.  Full disclosure: I am not a wizard at configurations so I am certain that these would not pass a proper design review but should suffice for this comparison.  I selected the IBM Power S822L, a Linux only system that includes 2 sockets, 24 cores @ 3.026 GHz,  1TB of memory, PowerVM, a pair of 146GB drives (just for boot and paging), a pair of dual-port 40GB Ethernet adapters, 3 years of 24/7 warranty and Linux support.  The price came out a little over $90K.  I then went to the HP web site and selected a DL580 Gen8 with a pair of E7-4480v2 2.8GHz/15 core processors, 1TB of memory, a couple of 120GB disk drives and 4 dual port 10GB Ethernet adapters, since they apparently don’t support the newer 40GB ones.  Before I even added OS and Virtualization, this config was already close to $62K.  Add VMware vSphere 5.5 and a 4 Guest, 2 socket RedHat license with 3 yr 24/7 support and the total is closing on $78K.  So, for a little over 15% higher cost, at list, you could get a system with over 50% more performance, radically better virtualization and far better reliability.  The reliability advantage alone, especially for Suite on HANA customers, would justify a far higher price tag.  Of course, this is just the first wave of systems and many customers will need far larger configurations.  As IBM has not announced those, as of yet, I can’t speculate where they will come in, price wise, but if you consider how far things have come in a very short time for Power, the future looks awfully bright.


One thing that I did not discuss above, other than in passing, is GPFS.  Not that GPFS is to be ignored, but remember, this will hopefully be an option, not a requirement.  This amazing, scale-out technology, is shared with our System x brethren.  It is a game changer for customers, offering not only outstanding performance but built in redundancy for data and log volumes for HANA.  It has been extensively tested by SAP, IBM and customers.  It already certified to scale-out to 56 nodes with System x and SAP has tested it in configurations with over 100 nodes.  If GPFS were added to the mix, for scale-out configurations, this would add substantial additional value over similar x86 configurations, other than those from IBM System x.


HANA on Power will enable not just freedom of choice for customers, but the mission critical reliability and performance that may have been holding them back from trying Suite on HANA.  We are looking forward to working with SAP and our customers to explore this exciting new offering.


Many thanks to my colleague, Bob Wolf, for his outstanding editing.

Rebuttal to “Why choose x86″ for SAP blog posting

I was intrigued by a recent blog post, entitled: Part 1: SAP on VMware : Why choose x86.  I will get to the credibility of the author in just a moment.  First, however, I felt it might be interesting to review the points that were made and discuss these, point by point.

  1. No Vendor Lock-in: When it comes to x86 world, there is no vendor lock-in as you can use any vendor and any make and model as per your requirements”.  Interesting that the author did not discuss the vendor lock-in on chip, firmware or hypervisor.  Intel, or to a very minor degree, AMD, is required for all x86 systems.   This would be like being able to choose any car as long as the engine was manufactured by Toyota (a very capable manufacturer but with a lock on the industry, might not offer the best price or innovation). As any customer knows, each x86 system has its own unique BIOS and/or firmware.  Sure, you can switch from one vendor to another or add a second vendor, but lacking proper QA, training, and potentially different operational procedures, this can result in problems.  And then there is the hypervisor with VMware clearly the preference of the author as it is for most SAP x86 virtualization customers.  No lock-in there?

SAP certifies multiple different OS and hypervisor environments for their code.  Customers can utilize one or more at any given time.  As all logic is written in 3rd and 4th GL languages, i.e. ABAP and JAVA, and is contained within the DB server, customers can move from one OS, HW platform and/or hypervisor to another and only have to, wait for it, do proper QA, training and modify operational procedures as appropriate.  So, SAP has removed lock-in regardless of OS, HW or hypervisor.

Likewise, Oracle, DB2 and Sybase support most OS’s, HW and hypervisors (with some restrictions).  Yes, a migration is required for movement between dissimilar stacks, but this could be said for moving from Windows to Linux and any move between different stacks still requires all migration activities to be completed with the potential exception of data movement when you “simply” change the HW vendor.

  1. Lower hardware & maintenance costs: x86 servers are far better than cheaper than non-x86 servers. This also includes the ongoing annual maintenance costs (AMC) as well.”  Funny, however, that the author only compared HW and maintenance costs and conveniently forgot about OS and hypervisor costs.  Also interesting that the author forgot about utilization of systems.  If one system is ½ the cost of another, but you can only drive, effectively, ½ the workload, then the cost is the same per unit of work.  Industry analysts have suggested that 45% utilization is the maximum sustained to be expected out of VMware SAP systems with most seeing far less.  By the same token, those analysts say that 85% or higher is to be expected of Power Systems.  Also interesting to note that the author did not say which systems were being compared as new systems and options from IBM Power Systems offer close to price parity with x86 systems when HW, OS, hypervisor and 3 years of maintenance are included.
  1. Better performance:  Some of the models of x86 servers can actually out-perform the non-x86 servers in various forms.”  Itanium is one of the examples, which is a no-duh for anyone watching published benchmarks.  The other example is a Gartner paper sponsored by Intel which actually does not quote a single SAP benchmark.  Too bad the author suggested this was a discussion of SAP.  Last I checked (today 2/10/14), IBM Power Systems can deliver almost 5 times the SAPS performance of the largest x86 server (as measured by the 2-tier SD benchmark).  On a SAPS/core basis, Power deliver almost 30% more SAPS/core compared to Windows systems and almost 60% more than Linux/x86 systems.  Likewise, on the 3-tier benchmark, the latest Power result is almost 4.5 times that of the latest x86 result.  So, much for point 3.
  1. Choice of OS: You have choice of using any OS of your choice and not forced to choose a specific OS.”  Yes, it really sucks that with Power, you are forced to choose, AIX … or IBM I for Business … or SUSE Linux … or RedHat Linux which is so much worse than being forced to choose Microsoft Windows … or Oracle Solaris … or SUSE Linux … or RedHat Linux.
  1. Disaster Recovery: You can use any type of hardware, make and model when it comes to disaster recovery (DR). You don’t need to maintain hardware from same vendor.”  Oh, really?  First, I have not met any customers that use one stack for production and a totally different one in DR, but that is not to say that it can’t be done.  Second, remember the discussion about BIOS and firmware?  There can be different patches, prerequisites and workarounds for different stacks.  Few customers want to spend all of the money they “saved” by investing in a separate QA cycle for DR.  Even fewer want to take a chance of DR not working when they can least afford it, i.e. when there is a disaster.  Interestingly, Power actually supports this better than x86 as the stack is identical regardless of which generation, model, mhz is used.  You can even run in Power6 mode on a Power7+ server further enabling complete compatibility regardless of chip type meaning you can use older systems in DR to back up brand new systems in production.
  1. Unprecedented scalability: You can now scale the x86 servers the way you want, TB’s of RAM’s , more than 64 cores etc is very much possible/available in x86 environment.”  Yes, any way that you want as long as you don’t need more capacity than is available with the current 80 core systems.  Any way that you want as long as you are not running with VMware which limits partitions to 128 threads which equates to 64 cores.  Any way that you want but that VMware suggests that you contain partitions within a NUMA block which means a max of 40 cores.  Any way that you want as long as you recognize that VMware partitions are further limited in terms of scalability which results in an effective limit of 32 threads/16 cores as I have discussed in this blog previously.
  1. Support from Implementation Vendor: “If you check with your implementation vendor/partner, you will find they that almost all of them can certify/support implementation of SAP on x86 environment. The same is the case if you are thinking about migrating from non-x86 to x86 world.”  No clue what point is being made here as all vendors on all supported systems and OSs support SAP on their systems.

The author referred to my blog as part of the proof of his/her theories which is the only reason why I noticed this blog in the first place.  The author describes him/herself as “Working with Channel Presales of an MNC”.  Interesting that he/she hides him/herself behind “MNC” because the “MNC” that I work for believes that transparency and honesty are required in all internet postings.  That said, the author writes about nothing but VMware, so you will have to draw your own conclusions as to where this individual works or with which “MNC” his/her biases lie.

The author, in the reference to my posting, completely misunderstood the point that I made regarding the use of 2-tier SAP benchmark data in projecting the requirements of database only workloads and apparently did not even read the “about me” which shows up by default when you open my blog.  I do not work for SAP and nothing that I say can be considered to represent them in any way.

Fundamentally, the author’s bottom line comment, “x86 delivers compelling total cost of ownership (TCO) while considering SAP on x86 environment” is neither supported by the facts that he/she shared nor by those shared by others.  IBM Power Systems continues to offer very competitive costs with significantly superior operational characteristics for SAP and non-SAP customers.

Is VMware ready for HANA production?

Virtualizing SAP HANA with VMware in productive environments is not supported at this time, but according to Arne Arnold with SAP, based on his blog post of Nov 5,, they are working hard in that direction.

Clearly memory can be assigned to individual partitions with VMware and to a more limited extent, CPU resources may also be assigned although this may be a bit more limited in its effectiveness.  The issues that SAP will have to overcome, however, are inherent limitations in scalability of VMware partitions, I/O latency and potential contention between partitions for CPU resources.

As I discussed in my blog post late last year,, VMware 5.0 was proven, by VMware, HP and Intel, to have severe performance limitations and scalability constraints.  In the lab test, a single partition achieved only 62.5% scalability, overall, but what is more startling is the scalability between each measured interval.  From 4 to 8 threads, they were able to double the number of users, thereby demonstrating 100% scalability, which is excellent.  From 8 to 16 threads, they were only about to handle 66.7% more users despite doubling the number of threads.  From 16 to 32 threads, the number of users supported increased only 50%.  Since the time of the study being published, VMware has released vSphere 5.1 with an architected limit of 64 threads per partition and 5.5 with an architected limited of 128 threads per partitions.  Notice my careful wording of architected limit not the official VMware wording, of “scalability”.  Scaling implies that with each additional thread, additional work can be accomplished.  Linear scaling implies that each time you double the number of threads, you can accomplish twice the amount of work.  Clearly, vSphere 5.0 was unable to attain even close to linear scaling.  But now with the increased number of threads supported, can they achieve more work?  Unfortunately, there are no SAP proof points to answer this question.  All that we can do is to extrapolate the results from their earlier published results assuming the only change was the limitation in the number of architected threads.  If we use the straight forward Microsoft Excel “trendline” function to project results using a Polynomial with an order of 2, (no, it has been way to long since I took statistics in college to explain what this means but I trust Microsoft (lol)) we see that a VMware partition is unlikely to ever achieve much more throughput, without a major change in the VMware kernel, than it achieved with only 32 threads.  Here is a graph that I was able to create in Excel using the data points from the above white paper.

VMware scalability curve

Remember, at 32 threads, with Intel Hyperthreading, this represents only 16 cores. As a 1TB BW HANA system requires 80 cores, it is rather difficult to imagine how a VMware partition could ever handle this sort of workload much less how it would respond to larger workloads.  Remember, 1TB = 512GB of data space which, at a 4 to 1 compression ratio, equal 2TB of data.  VMware starts to look more and more inadequate as data size increases.

And if a customer was misled enough by VMware or one of their resellers, they might think that using VMware in non-prod was a good idea.  Has SAP or a reputable consultant ever recommended using use one architecture and stack in non-prod and a completely different one in prod?

So, in which case would virtualizing HANA be a good idea?  As far as I can tell, only if you are dealing with very small HANA databases.  How small?  Let’s do the math:   assuming linear scalability (which we have already proven above is not even close to what VMware can achieve) 32 threads = 16 cores which is only 20% of the capacity of an 80 core system.  20% of 2TB = 400GB of uncompressed data.  At the 62.5% scalability described above, this would diminish further to 250GB.  There may be some side-car applications for which a large enterprise might replicate only 250GB of data, but do you really want to size for the absolute maximum throughput and have no room for growth other than chucking the entire system and moving to newer processor versions each time they come out?  There might also be some very small customers which have data that can currently fit into this small a space, but once again, why architect for no growth and potentially failure?  Remember, this was a discussion only about scalability, not response time.  Is it likely that response time also degrades as VMware partitions increase in size?  Silly me!  I forgot to mention that the above white paper showed response time increasing from .2 seconds @ 4 threads to 1 second @ 32 threads a 400% increase in response time.  Isn’t the goal of HANA to deliver improved performance?  Kind of defeats the purpose if you virtualize it using VMware!

High end Power Systems customers have a new option for SAP app servers that is dramatically less expensive than x86 Linux solutions

Up until recently, if you were expanding the use of your SAP infrastructure or have some older Power Systems that you were considering replacing with x86 Linux systems, I could give you a TCO argument that showed how you could see roughly equivalent TCO using lower end Power Servers.  Of course, some people might not buy into all of the assumptions or might state that Linux was their new standard such that AIX was no longer an acceptable option.  Recently, IBM made an announcement which has changed the landscape so dramatically that you can now obtain the needed capacity using high end server “dark cores” with Linux, not at an equivalent TCO, but at a dramatically lower TCA.

The new offering is called IFL which stands for Integrated Facility for Linux.  This concept originated with System Z (aka mainframe) several years ago.  It allows customers that have existing Power 770, 780 or 795 servers with capacity on demand “dark cores”, i.e. for which no workload currently runs and the license to use the hardware, virtualization and OS software have not been activated, to turn on a group of cores and memory specifically to be used for Linux only workloads.  A Power IFL is composed of 4 cores with 32GB of memory and has a list price of $8,591.

In the announcement materials provided by IBM Marketing, an example is provided of a customer that would need to add the equivalent of 16 cores @ 80% utilization and 128GB of memory to an existing Power 780 4.4GHz system or would need the equivalent capacity using a 32-core HP DL560 2.7GHz system running at 60% utilization.  They used SPECint_rate as the basis of this comparison.  Including 3 year license for PowerVM, Linux subscription and support, 24×7 hardware maintenance and the above mentioned Power activations, the estimated street price would be approximately $39,100.  By comparison, the above HP system plus Linux subscription and support, VMware vSphere and 24×7 hardware maintenance would come in at an estimated street price of approximately $55,200.

Already sounds like a good deal, but I am a skeptic, so I needed to run the numbers myself.  I find SPECint_rate to be a good indicator of performance for almost no workloads and an incredibly terrible indicator of performance for SAP workloads.  So, I took a different approach.  I found a set of data from an existing SAP customer of IBM which I then used to extrapolate capacity requirements.  I selected the workloads necessary to drive 16 cores of a Power 780 3.8GHz system @ 85% utilization.  Why 85%?  Because we, and independent sources such as Solitaire Interglobal, have data from many large customers that report routinely driving their Power Systems to a sustained utilization of 85% or higher.  I then took those exact same workloads and modeled them onto x86 servers assuming that they would be virtualized using VMware.  Once again, Solitaire Interglobal reports that almost no customers are able to drive a sustained utilization of 45% in this environment and that 35% would be more typical, but I chose a target utilization of 55% instead to make this as optimistic for the x86 servers as possible.  I also applied only a 10% VMware overhead factor although many sources say that is also optimistic.  It took almost 6 systems with each hosting about 3 partitions to handle the same workload as the above 16-core IFL pool did.

Once again, I was concerned that some of you might be even more optimistic about VMware, so I reran the model using a 65% target utilization (completely unattainable in my mind, but I wanted to work out the ultimate, all stars aligned, best admins on the planet, tons of time to tune systems, scenario) and 5% VMware overhead (I don’t know anyone that believes VMware overhead to be this low).  With each system hosting 3 to 4 partitions, I was able to fit the workloads on 5 systems.  If we just go crazy with unrealistic assumptions, I am sure there is a way that you could imagine these workloads fitting onto 4 systems.

Next, I wanted to determine the accurate price for those x86 systems.  I used HP’s handy on-line ordering web site to price some systems.  Instead of the DL560 that IBM Marketing used, I chose the DL360e Gen8 system, with 2@8-core 1.8GHz processors, 64GB of memory, a pair of 7200rpm 500GB hard drives, VMware Enterprise for 2 processors with 3 yr subscription, RH Enterprise Linux 2 socket/4 guest with 3 yr subscription, 3yr 24×7  ProCare Service and HP installation services.  The total price comes to $27,871 which after an estimated discount of 25% on everything (probably not realistic), results in a street price of $20,903.

Let’s do the math.  Depending on which x86 scenario you believe is reasonable, it either takes 6 systems at a cost of $125,419, 5 systems @ $104,515 or 4 systems @ $83,612 to handle the same load as a 4 IFL/16-core pool of partitions on a 780 at a cost of $39,100.  So, in the most optimistic case for x86, you would still have to pay $44,512 more.  It does not take a rocket scientist to realize that using Power IFLs would result in a far less expensive solution with far better reliability and flexibility characteristics not to mention better performance since communication to/from the DB servers would utilize the radically faster backplane instead of an external TCP/IP network.

But wait, you say.  There is a better solution.  You could use bigger x86 systems with more partitions on each one.  You are correct.  Thanks for bringing that up.  Turns out, just as with Power Systems, if you put more partitions on each VMware system, the aggregate peaks never add up to the sum of the individual peaks.  Using 32-core, DL560s @ 2.2GHz, 5% VMware overhead and 65% target utilization, you would only need 2 systems.  I priced them on the HP web site with RH Linux 4 socket/unlimited guests 3yr subscription, VMware Enterprise 4 socket/3yr, 24×7 ProCare and HP installation service and found the price to be $70,626 per system, i.e. $141,252 for two systems, $105,939 after the same, perhaps unattainable 25% discount.  Clearly, 2 systems are more elegant than 4 to 6, but still, this solution is still $66,839 more expensive than the IFL solution.

I started off to try and prove that IBM Marketing was being overly optimistic and ended up realizing that they were highly conservative.  The business case for using IFLs for SAP app servers on an existing IBM high end system with unutilized dark cores compared to net new VMware/Linux/x86 systems is overwhelming.  As many customers have decided to utilize high end Power servers for DB due to their reliability, security, flexibility and performance characteristics, the introduction of IFLs for app servers is almost a no-brainer.

The hype and the reality of HANA

Can you imagine walking into a new car dealership and before you can say anything about your current vehicle and needs, a salesperson  immediately offers to show you the latest, greatest and most popular new car!  Of course you can since this is what that person gets paid to do.  Now, imagine the above scenario where the salesperson says “how is your current car not meeting your needs?” and following it up with “I don’t want you to buy anything from me unless it brings you substantial value”.  After smelling salts have been administered, you might recover enough to act like a cartoon character trying to check your ears to make sure they are functioning properly and ask the salesperson to repeat what he or she said.

The first scenario is occurring constantly with SAP account execs, systems integrators and consultants playing the above role of new car salesperson.  The second rarely happens, but that is exactly the role that I will play in this blog post.

The hype around HANA could not be much louder and deep than it is currently.  As bad as it might be, the FUD (Fear, Uncertainty and Doubt) is worse.  The hype suggests that HANA can do everything except park your car since that is a future capability (not really, I just made that up.)  At the very worst, this hype suggests a vision for the future that, while not solving world hunger or global warming, might improve the operations and profitability of companies.  The second is more insidious.  It suggests that unless you act like lambs and follow the lead of the individual telling this tale, you will be like a lost sheep, out of support and further out of the mainstream.

I will address the second issue first.  As of today, the beginning of August, SAP has made absolutely no statement indicating they will discontinue support for any platform, OS or DB.  In fact, a review of SAP notes shows support for most OS’s with no end date and even DB2 9.7 has an end of support date that is several years past that of direct standard support from IBM!  So, what gives???  Is SAP saying one thing internally and another externally?  I have been working with SAP for far too long and know their business practices too well to believe that they would act in such a two-faced manner not to mention exposing themselves to another round of expensive and draining lawsuits.  Instead, I place the arrow of shame squarely on those rogue SAP account execs that are perpetuating this story.  The next time that one of them makes this sort of suggestion, turn the tables on them.  Ask them to provide you with a statement, in writing, backed up with official press releases or SAP notes, showing that this is the case.  If they can’t, it is reasonable to conclude that they are simply trying to use the age old FUD tactic to get you to spend more money with them now rather than waiting until/if SAP actually decides to stop supporting a particular type of HW, OS or DB.

And now for the first issue; the hype around HANA.  HANA offers dramatic benefits to some SAP customers.  Some incarnation of HANA may indeed be inevitable for the vast majority.  However, the suggestion that HANA is the end-all be-all flies in the face of many other solutions on the market, many of which are radically less expensive and often have dramatically lower risk.  Here is a very simple example.

Most customers would like to reduce the time and resources required to run batch jobs.  It seems as if there is not a CFO anywhere that does not want to reduce month end/quarter close from multiple days down to a day or less.  CFOs are not the only ones with that desire as certain functions must come to a halt during a close and/or the availability requirements go sky high during this time period requiring higher IT investments.  SAP has suggested that HANA can achieve exactly this, however it is not quite clear whether this will require BW HANA, Suite on HANA or some combination of the two or even another as yet unannounced HANA variant.  I am sure that if you ask a dozen consultants, you will get a dozen different answer to how to achieve these goals with HANA and it is entirely possible that each of them are correct in their own way.  One thing is certain however: it won’t come cheaply.  Not only will a company have to buy HANA HW and SW, but they will have to pay for a migration and a boatload of consulting services.  It will also not come without risk.  BW HANA and Suite on HANA require a full migration.  Those systems become the exclusive repository of business critical data.  HANA is currently in its 58th revision in a little over two years.  HA, DR and backup/recovery tools are still evolving.  No benchmarks for Suite on HANA have been published which means that sizing guidelines are based purely on the size of the DB, not on throughput or even users.  Good luck finding extensive large scale customer references or even medium sized ones in your industry.   To make matters worse, a migration to HANA is a one way path.  There is no published migration methodology to move from HANA back to a conventional DB.  It is entirely possible that Suite on HANA will be much more stable than BW HANA was, that these systems will scream on benchmarks,  that all of those HA, DR, Backup/Recovery and associated tools will mature in short order and that monkeys will fly.  Had the word risk not been invented previously, Suite on HANA would probably be the first definition in the dictionary for it.

So, is there another way to achieve those goals, maybe one that is less expensive, does not require a migration, software licenses or consulting services?  Of course not because that would be as impossible to believe as the above mentioned flying monkeys.   Well, strap on your red shoes and welcome to Oz, because it is not only possible but many customers are already achieving exactly those gains.  How?  By utilizing high performance flash storage subsystems like the IBM FlashSystem.  Where transaction processing typically accesses a relatively small amount of data cached in database buffers, batch, month end and quarter close jobs tend to be very disk intensive.  A well-tuned disk subsystem can deliver access speeds of around 5 milliseconds.  SSDs can drop this to about 1 millisecond.   A FlashSystem can deliver incredible throughput while accessing data in as little as 100 microseconds.   Many customers have seen batch times reduced to a third or less than what they experienced before implementing FlashSystem.  Best of all, there are no efforts around migration, recoding, consulting and no software license costs.  A FlashSystem is “just another disk subsystem” to SAP.  If an IBM SVC (SAN Volume Controller) or V7000 is placed in front of a FlashSystem, data can be transparently replicated from a conventional disk subsystem to FlashSystem without even a system outage.  If the subsystem does not produce the results expected the system can be repurposed or, if tried out via a POC, simply returned at no cost.  To date, few, if any, customers have returned a FlashSystem after completing a POC as they have universally delivered such incredible results that the typical result is an order for more units.

Another super simple, no risk option is to consider using the old 2-tier approach to SAP systems.  In this situation, instead of utilizing separate database and application server systems/partitions, database and app server instances are housed within a single OS system/partition.  Some customers don’t realize how “chatty” app servers are with an amazing number of very small queries and data running back and forth to DB servers.  As fast as Ethernet is, it is as slow as molasses compared to the speed of an inter-process communication within an OS.  As crazy as it may seem, simply by consolidating DB and app servers into a single OS, batch and close activity may speed up dramatically.  And here is the no risk part.  Most customers have QA systems and from an SAP architecture perspective, there is no difference in having app servers within a single OS compared to on separate OSs.  As a result, customers can simply give it a shot and see what happens.  No pain other than a little time to set up and test the environment.  Yes, this is the salesman telling you not to spend any money with him.

This is not the only business case for HANA.  Others involve improving reporting or even doing away with reporting in favor of real-time analytics.  Here is the interesting part.  Before Suite on HANA or even BW HANA became available, SAP had introduced real-time replication into side-car HANA appliances.    With these devices, the source of business critical data is kept on conventional databases.  You remember those archaic old systems that are reliable, secure, scalable and around which you have built a best practices environment not to mention have purchased a DB license and are simply paying maintenance on it.  Perhaps naively, I call this the 95-5 rule, not 80-20.  You may be able to achieve 95% of your business goals with such a side-car without risking a migration or the integrity of your data.   Also, since you will be dealing with a subset of data, the cost of the SW license for such a device will likely be a small fraction of the cost of an entire DB.  Even better, as an appliance, if it fails, you just replace the appliance as the data source has not been changed.  Sounds too good to be true?  Ask your SAP AE and see what sort of response you get.  Or make it a little more interesting and suggest that you may be several years away from being ready go to Suite on HANA but could potentially do a side-car in the short term and observe the way the shark will smell blood in the water.  By the way, since you have to be on current levels of SAP software in order to migrate to Suite on HANA and reportedly 70% of customers in North America are not current, (no idea of the rest of the world) so this may not even be much or a stretch.

And I have not even mentioned DB2 BLU yet but will leave that for a later blog posting.

A brilliant view of HANA

This third party take on HANA is intriguing and funny but certainly makes you think.  I rarely just post a link to another blog without editorial, but this one stands on its own.

SAP HANA on Power – status update

This entry has been superseded by a new one:


After Vishal Sikka’s announcement that SAP was investigating the potential of HANA on IBM Power Systems, it seemed that all that was needed for this concept to become a reality was for IBM to invest in the resources to aid SAP in porting and optimization of SAP HANA on Power (HoP) and for customers to weigh in on their desire for such a solution.

Many, very large customers told us that they did let SAP know of their interest in HoP.  IBM and SAP made the necessary investments for a proof of concept with HoP.  This successful effort was an example of the outstanding results that happen when two great companies cooperate and put some of their best people together.  However, there are still no commitments to deliver HoP in 2013.  SAP apparently has not ruled out such a solution at some point in the future.  So, why should you care since HANA already runs on x86?

Simple answer.  Are you ready to bet your business on x86?  

Do Intel systems offer the scalability that your business requires and can those systems react fast enough to changing business conditions?  Power scales far high than x86, has no artificial limitations and responds to changing demands almost instantly.

Are x86 systems reliable enough?   Power Systems inherited a wide array of self correcting and fault tolerant features from the mainframe, still the standard for reliability in the industry.

Are x86 systems secure enough?   Despite the best attempts by hackers, PowerVM has still never been breached.

Can you exploit virtualization or will you have to go back to a 1990s concept of islands of automation?  The PowerVM hypervisor is part of every Power system, so it is virtualized by default and the journey that most customers have been on for most of this millennium can continue unabated.

What can you do about this?  Speak up!!  Call your SAP Account Executive and send them notes.  Let them know that you are unwilling to take a chance on allowing your SAP Business Suite database systems to be placed on anything less than the most reliable, scalable, secure and flexible systems available, i.e. IBM Power Systems.    Remind SAP that Business Suite DB already runs very well on current Power Systems and that until SAP is willing to support this platform for HANA, there is very little compelling reason for you to consider a move to HANA.

Sapphire is just a week away.  This may be the best opportunity for you to deliver this message as most of SAP’s leadership will be present in Orlando.  If they hear this message from enough customers, it is unlikely that they will simply ignore it.

8) Localizing the Global Template ? A Global SAP Transformation Challenge

ASUG session 1505

More and more multinational companies are either consolidating their world-wide SAP instances or embarking on green-field, global SAP-based transformation projects. These implementations are often complex and difficult. Typically, the integration of global operations running on a single SAP platform requires more careful and systematic consideration of all business requirements, both global and local, as they may sometimes be conflicting with each other, confusing, and/or be missed out completely. In many cases, the consequences will be long lasting, if not permanent. But this does not have to happen. How do we bring all these puzzles together while keeping two basic principles intact: 1) enabling the creation of a global template with common core processes and 2) successfully staging deployment (only adding incremental legal and regulatory requirements) so as to manage project costs, risks, and return on investment (ROI). Among other things, presenters will discuss a robust approach and look at corners of the world where legal and regulatory requirements are most challenging and needs to be considered upfront during the global blueprint. They will explore localization accelerators and requirement databases. Presenters will also have a lively discussion on the intricacies of global cultures and how to strategically optimize the strength of each of these teams from Blueprint to Go-Live.

9) At IBM, Complex Offerings Just Got a Lot Less Complicated

ASUG Session 3506

The first rule of business: don’t sell products, sell solutions. Well, easier said than done,   particularly for industries dealing with complex products and services.

10) SAP Enterprise Application Strategy in the Era of SAP HANA, Infrastructure, Platforms, Software and Everything as a Service

ASUG Session 2309

What are the forces that will shape your enterprise application landscape? How will SAP’s strategy of “on-premise” and “off-premise” impact your company’s strategy? What are the rules that can make your company’s strategy successful and what are pitfalls? What major shifts in technology and business might derail your strategy? Presenters will discuss several major company’s strategies to date. They’ll discuss how to use private, hosted, and public cloud successfully today. Finally, they’ll give attendees several tools to help any company navigate the complex future.

11) SAP Enabled Procurement Transformation Lessons Learned at General Motors

Why SAP HANA on IBM Power Systems

Before you get the wrong impression, SAP has not announced the availability of HANA on Power and in no way, should you interpret this posting as any sort of pre-announcement.  This is purely a discussion about why you should care whether SAP decides to support HANA on Power .


As you may be aware, during SAP’s announcement of the availability of HANA for Business Suite DB for ramp-up customers in early January, Vishal Sikka, Chief Technology Officer and member of the Executive Board at SAP, stated “We have been working heavily with [IBM].  All the way from lifecycle management and servers to services even Cognos, Business Intelligence on top of HANA – and also evaluating the work that we have been doing on POWER.  As to see how far we can be go with POWER - the work that we have been doing jointly at HPI.  This is a true example of open co-innovation, that we have been working on.”  Ken Tsai, VP of SAP HANA product marketing, later added in an interview with IT Jungle,  “Power is something that we’re looking at very closely now.”  And from Amit Sinha, head of database and technology product marketing. “[HANA] on Power is a research project currently sponsored at Hasso Plattner Institute. We await results from that to take next meaningful steps jointly with IBM,”  Clearly, something significant is going on.  So, why should you care?


Very simply, the reasons why customers chose Power Systems (and perhaps HP Integrity and Oracle/Fujitsu SPARC/Solaris) for SAP DBs in the past, i.e. scalability, reliability, security, are just as relevant now with HANA as in the past with conventional databases, perhaps even more so.  Why more so?  Because once the promise of real time analytics on an operational database is realized, not necessarily in Version 1.0 of the product, but in the future undoubtedly, then the value obtained by this capability would result in the exact same loss of value if the system was not available or did not respond with the speed necessary for real time analytics.


A little known fact is that HANA for Business Suite DB currently is limited to a single node.  This means that scale out options, common in the BW HANA space and others, is not an option for this implementation of the product.  Until that becomes available, customers that wish to host large databases may require a larger number of cores than x86 vendors currently offer.


A second known but often overlooked fact is that parallel transactional database systems for SAP are often complex, expensive and have so many limitations that only two types of customers consider this option; those which need continuous or near continuous availability and those that want to move away from a robust UNIX solution and realize that to attain the same level of uptime as a single node UNIX system with conventional HA, an Oracle RAC or DB2 PureScale cluster is required.  Why is it so complex?  Without getting into too much detail, we need to look at the way SAP applications work and interact with the database.  As most are aware, when a user logs on to SAP, they are connecting to a unique application server and until they log off, will remain connected to that server.  Each application server is, in turn, connected to one node of a parallel DB cluster.  Each request to read or write data is sent to that node and if the data is local, i.e. in the memory of that node, the processing occurs very rapidly.  If, on the other hand, the data is on another node, that data must be moved from the remote node to the local node.  Oracle RAC and DB2 PureScale use two different approaches with Oracle RAC using their Cache Fusion to move the data across an IP network and DB2 PureScale using Remote DMA to move the data across the network without using an IP stack, thereby improving speed and reducing overhead.  Though there may be benefits of one over the other, this posting is not intended to debate this point, but instead point out that even with the fastest, lowest overhead transfer on an Infiniband network, access to remote memory is still thousands of time slower than accessing local memory.


Some applications are “cluster aware”, i.e. application servers connect to multiple DB nodes at the same time and direct traffic based on data locality which can only be possible if the DB and App servers work cooperatively to communicate what data is located where.  SAP Business Suite is not currently cluster aware meaning that without a major change in the Netweaver Stack, replacing a conventional DB with a HANA DB will not result in cluster awareness and the HANA DB for Business Suite may need to remain as a single node implementation for some time.


Reliability and Security have been the subject of previous blog posts and will be reviewed in some detail in an upcoming post.  Clearly, where some level of outages may be tolerable for application servers due to an n+1 architecture, few customers consider outages of a DB server to be acceptable unless they have implemented a parallel cluster and even then, may be mitigated, but still not considered tolerable.  Also, as mentioned above, in order to achieve this, one must deal with the complexity, cost and limitations of a parallel DB.  Since HANA for Business Suite is a single node implementation, at least for the time being, an outage or security intrusion would result in a complete outage of that SAP instance, perhaps more depending on interaction and interfaces between SAP components.  Power Systems has a proven track record among Medium and Large Enterprise SAP customers of delivering the lowest level of both planned and unplanned outages and security vulnerabilities of any open system.


Virtualization and partition mobility may also be important factors to consider.  As all Power partitions are by their very definition “virtualized”, it should be possible to dynamically resize a HANA DB partition, host multiple HANA DB partitions on the same system and even move those partitions around using Live Partition Mobility.  By comparison, an x86 environment lacking VMware or similar virtualization technology could do none of the above.  Though, in theory, SAP might support x86 virtualization at some point for production HANA Business Suites DBs, they don’t currently and there are a host of reasons why they should not which are the same reasons why any production SAP databases should not be hosted on VMware as I discussed in my blog posting:   Lacking x86 virtualization, a customer might conceivably need a DB/HA pair of physical machines for each DB instance compared to potentially a single DB/HA pair for a Power based virtualized environment.


And now a point of pure speculation; with a conventional database, basis administrators and DBAs weigh off the cost/benefit of different levels in a storage hierarchy including main memory, flash and HDDs.  Usually, main memory is sized to contain upwards of 95% of commonly accessed data with flash being used for logs and some hot data files and HDDs for everything else.  For some customers, 30% to 80% of an SAP database is utilized so infrequently that keeping aged items in memory makes little sense and would add cost without any associated benefit.  Unlike conventional DBs, with HANA, there is no choice.  100% of an SAP database must reside in memory with flash used for logs and HDDs used for a copy of the data in memory.  Not only does this mean radically larger amounts of memory must be used but as a DB grows, more memory must be added over time.  Also, more memory means more DIMMS with an associated increase in DIMM failure rates, power consumption and heat dissipation.  Here Power Systems once again shines.  First, IBM offers Power Systems with much larger memory capabilities but also offers Memory on Demand on Power 770 and above systems.  With this, customers can pay for just the memory they need today and incrementally and non-disruptively add more as they need it.  That is not speculation, but the following is.  Power Systems using AIX offers Active Memory Expansion (AME), a unique feature which allows infrequently accessed memory pages to be placed into a compress pool which occupies much less space than uncompressed pages.  AIX then transparently moves pages between uncompressed and compressed pools based on page activity using a hardware accelerator in POWER7+.  In theory, a HANA DB could take advantage of this in an unprecedented way.  Where test with DB2 have shown a 30% to 40% expansion rate (i.e. 10GB of real memory looks like 13GB to 14GB to the application), since potentially far more of a HANA DB would have low use patterns that it may be possible to size the memory of a HANA DB at a small fraction of the actual data size and consequently at a much lower cost plus associated lower rates of DIMM failures, less power and cooling.


If you feel that these potential benefits make sense and that you would like to see a HoP option, it is important that you share this desire with SAP as they are the only ones that can make the decision to support Power.  Sharing your desire does not imply that you are ready to pull the trigger or that you won’t consider all available option, simply that you would like to get informed about SAP’s plans.  In this way, SAP can gauge customer interest and you can have the opportunity to find out which of the above suggested benefits might actually be part of a HoP implementation or even get SAP to consider supporting one or more of them that you consider to be important.  Customers interested in receiving more detailed information on the HANA on Power effort should approach their local SAP Account  Executive in writing, requesting disclosure information on this platform technology effort.
