Talk:IBM System z9

s390
Currently, 's390' and 's/390' redirect here, but the page gives no explicit mention of those terms. Should 's390' redirect to 'esa/390'? --Apantomimehorse 08:10, 16 August 2006 (UTC)


 * Both S390 and S/390 previously redirected to IBM ESA/390. S390X and S/390X redirect to this article, which appears to be correct since IBM internal websites refer to them as 'z' products. SBaker43 (talk) 16:10, 2 November 2011 (UTC)

Statistics
Are there any vital stats for these mainframes? Perhaps # of GFlops/second?


 * IBM publishes &ldquo;MIPS&rdquo;/&ldquo;MSU&rdquo; numbers for use in their, ehr, unique mainframe software billing scheme, but those aren't benchmark results. Searching for &ldquo;IBM&rdquo; and &ldquo;GFLOPS&rdquo; turns up a lot of references to IBM POWER AIX systems, but none for recent mainframes.  (I believe there are some LINPACK benchmarks measurements for the ES/9000 era of machines.)  There are also a few Web pages by IBM cheerleaders trying to &ldquo;explain&rdquo; how benchmarks like LINPACK, LFK, SPEC, etc., are all bad and misleading because they don't take into consideration how IBM's mainframe machines are &ldquo;balanced for a mixed workload&rdquo;, or some similar marketing-speak that is reproduced so perfectly from one Web site to another that it's clear they're all reading from some HQ-approved script.  Overall, IBM isn't shy about GFLOPS when bragging about its Blue Gene or POWER product lines; one would expect that, if the mainframe product line had processor performance to be proud of, that IBM would brag about that, too.  Instead, the mainframe side belittles the very benchmarks that rank the Blue Gene side so highly.  Clearly GFLOPS aren't valued by either the mainframe builders or the mainframe customers.

System z9 EC GA3 (Genreal Availability) functions were announced on April 18, 2007 and delivered on May 11, 2007. There were about 20 new functions and features added to IBM's current generation of mainframes. Some functions were rather small in reach and value(a bolt down kit to hold the server in place during earthquakes...) and others had great value add for almost every business running a z9. Group LPAR Capping, XML for specialty engines, IPSec on zIIPs, Hardware Decimal Floating Point, power + cooling monitoring and a power estimation tool were welcome adds by many mainframe Customers. The z9 is now know as help for Data Centers running out of power and cooling capacity or just assisting some in becoming more green. In fact the z9 has come to be known as "z9 Lean and Green" since it can consolidate hundreds or even thousands of servers into its power efficient and very reliable footprint. Rumor has that its MTBF is around 75 years and continues to climb towards 100 year MTBF, a measurement of the entire field population of the System z9.

Recently IBM highlighted that the watts / Million Instructions Per Second (MIPS is a measure of performance)has been dropping with every new generation of CMOS mainframe. This improving power efficiency is welcome help for many stressed Data Center facility power budgets. The System z9 has approximately 1 Watt/MIPS.
