Dear list, we are a shop with a z890-230 with three zOS.e LPARs in Basic Sysplex. We'd be really happy to consolidate some of our applications running right now on Blades and/or pSeries on the mainframe due to reliability and scalability of the latter. Within the Try&Buy agreement with IBM we got one IFL and 16 GB memory on the fly (just a microcode update), added two zLinux LPARs to be run in native and installed DB2 8.2.2 onto SuSE Enterprise 9. Well, the first results we have been having are pretty discouraging. We have been running some benchmarks in form of scripts on 4 different machines pSeries Power 3, two PPC3 @ 450 MHz; Intel-based board with two Pentium 3 @ 933 MHz; z890, 1IFL @ 1,3GHz (?) OpenPower 720, 2 PPC5 @ 1,6 GHz
and all benchmarks show that our IFL is *FAR* behind the Power5 architecture (round 20.000 Eur). Somehow, too slow to be true .... Without not going too much in detail about what the benchmarks did, they performed operations like loading and selects over joined tables - basic database I/O tasks. Either we are doing something conceptually wrong, or we are expecting too much from the IFL and/or zLinux. Comments, remarks, recommendations, pointer to further documentation are really welcome.
