Digging into SAP HANA on HP

with one comment

All of the snow has finally melted in my backyard. And what that means to me is that I don’t have to shovel for awhile. What that means to my dog is another story.

It’s a field day for him. Now he can get back to what he surely thinks is his real job – digging in the dirt. And what has he found? A plastic flower pot that he can chew on. 3 beat up tennis balls from the summer. A soup bone from 3 months ago. Treasures.

HP just announced this morning that they are delivering a “System with Faster Analytics Engine for SAP HANA Environments.” HP claims a 2x performance advantage over other solutions. Let’s dig into this claim and take a look at the facts:

  • The performance claim is based on the SAP BW Extended Mixed Workload Benchmark, a benchmark with only 4 results. And 3 of those results are from, you guessed it, HP.
  • The SAP BW-EML benchmark results that HP references in their footnote in this press release are from September 2013 — a lifetime ago in the benchmark world.
  • The HP system they reference in the press release is not even the system that is in the benchmark. HP’s new system is not even available.
  • Even if you did try to compare the HP and IBM results, it does not make sense. The HP and IBM results are in different categories of the benchmark, using a different number of records. The HP result used an application and database tier; the IBM result is on a central server.
  • Even if you ignored the fact that it doesn’t make sense to compare these results, if you do, the HP result used 2.5x the processing cores, 2x the memory, 4x the L1 cache, 2x the L2 cache per core. So the IBM result actually has 28% better throughput per core than the HP result.(1)

Please HP, dig more and come up with some new exciting treasures next time so we readers are not left in the dirt.


(1) IBM Power System 7 Express Server Central Server: IBM Power System 750 Express Server, 4 processor / 32 cores / 128 threads, POWER7+, 4.06GHz, 32KB(D) + 32KB(I) L1 cache and 256KB L2 cache per core, 10MB L3 cache per core, 512GB main memory; certification #2013020 (SUSE Linux Enterprise Server 11, DB2 for I 7.1, SAP NetWeaver 7.30, 66,900 ad-hoc navigation steps/hr) vs.
SAP BW-EML Benchmark: Database tier: HP ProLiant DL580 G7, 4 processor / 40 cores / 80 threads, Intel Xeon Processor E7-4870, 2.40GHz, 64KB L1 cache and 256KB L2 cache per core, 30MB L3 cache per processor, 512GB main memory; Application tier: HP ProLiant BL680 G7, 4 processor / 40 cores / 80 threads, Intel Xeon Processor E7-4870, 2.40GHz, 64KB L1 cache and 256KB L2 cache per core, 30MB L3 cache per processor, 512GB main memory; certification #2013027 (SUSE Linux Enterprise Server 11,SAP HANA 1.0,SAP NetWeaver 7.30,129,930 ad-hoc navigation steps/hr) Results current as of 3/19/14.

  1. I’m sure people would like to see a BW-EML result for DB2 10.5 with BLU acceleration.

    The only reason we haven’t see this yet, I suspect, is that the benchmark makes heavy use of ODS tables, not just fact tables, and currently SAP only supports the latter with BLU. Hence DB2 is at a disadvantage to HANA.

    Nevertheless I think it would be interesting, throwing Power8 and Flashsystem into the mix maybe for a good price performance result.
