Notable Quotable…

“I predict that the last mainframe will be unplugged on March 15, 1996”Stewart Alsop, former InfoWorld columnist (now at Fortune Magazine), March, 1991

Annual growth in MIPS of over 30% since 1992

More than $20B in mainframe revenue since 1996 (when the last one was to have been unplugged…)

But there have been many changes in the mainframe since 1991!

1 Based on preliminary internal measurements and projections against a z196. Official performance data will be available upon announce and can be obtained online at LSPR (Large Systems Performance Reference) website at:

https://www.ibm.com/servers/resourcelink/lib03060.nsf/pages/lsprindex . Actual performance results may vary by customer based on individual workload, configuration and software levels.

• Advanced Technology 5.5 GHz 6-core processor chip delivers a performance boost for all workloads

• Innovation to drive availability to superior levels – IBM zAware offers snap-shot of the current

state of your business– FLASH Express and pageable large pages to

drive availability and performance for critical workloads

• Trusted resilience is a zEnterprise standard

zEnterprise EC12 is the core of next generation of System z
