IBM: "Converge your data center on your terms" http://www-03.ibm.com/systems/info/x86servers/blades/servers/index.html above fumbled a little bit, e5-2600 is two chip, 8-core/chip, 16 core. IBM has a whole slew of e5-2600 benchmarks here https://www-304.ibm.com/easyaccess1/fileserve?contentid=232077 can anybody find similar numbers for z196 and/or EC12?? ibm has e5-2600 in number of server products http://www-03.ibm.com/systems/x/news/20120306_announce/index.html not just hs23. This claims the highest density per rack footprint http://www-03.ibm.com/systems/x/hardware/rack/dx360m4/index.html not e5-2600 ... but more ibm i86 benchmarks (from aug&sep 2011) http://benchmarkingblog.wordpress.com/category/x3850/ note that disks will be the same across the three technologies, however i86 and risc will frequently have an edge over mainframe w/o the overhead of the additional layer to simulate CKD (ckd disks haven't been manufactured for decades, being emulated on industry standard disks). some recent server-class disk i/o 5Gbyte/second, 724K IOPS (i/o operations per second) http://www.servethehome.com/lsi-9202-16/ 6.6Gbyte/second, 450K IOPS http://www.marketwatch.com/story/adaptec-by-pmc-transforms-data-center-storage-architectures-with-industrys-highest-port-count-pcie-gen3-raid-adapters-2012-09-05 e5-2600 based servers ... lsi http://www.scsita.org/library/2012/03/lsi-sas-technology-powers-over-200-new-server-models-based-on-the-intel-xeon-processor-e5-2600-produ.html more e5-2600 ... adaptec http://www.scsita.org/library/2012/03/adaptec-doubles-server-storage-performance-and-bandwidth-in-cebit-demo-featuring-pcie-30-on-the-inte.html -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
