Mieritz, M. Willis-Fleming – Gartner, 2004 Data center staffing levels have not significantly changed despite large increase in volume. 2004 13,272 MIPS 5,994 MIPS 260 Ops Staff 289 Ops Staff 2001

15. 1Q2009 z/OS and Workload Management TGVL: System z Foundation 15 Learning Points - z/OS and Workload Management 1.z/OS – IBM’s flagship Operating System 2.Current Release of z/OS – V1R10 3.z/OS release that requires z Architecture Server – V1R6 (and beyond) 4.z/OSe supports only z/800, z/890, and z9 BC. z/OSe does not support CICS, IMS, or COBOL Development 5.zNALC now replaces z/OSe and is intended for New Workloads on System z and significantly lowers the cost of z/OS – zNALC only effects the cost of z/OS 6.WLM is a standard subset of z/OS – no additional charge 7.WLM distributes resources among workloads according to customer business priorities (Described within Policies set by the customer) across a Parallel Sysplex 8.IRD is a subset of PR/SM 9.IRD works with WLM to dynamically distribute Processor and I/O hardware resources among LPARs running on the same physical server 10.IBM’s goal is to train 20,000 additional Mainframe professionals before 2010
