System z LSPR ITR ratios for IBM processors where each model is configured with multiple z/OS images based on an average LPAR profile of client systems

All capacity numbers are relative to the System z 2094-701 running a single z/OS image. Information presented in this table is current as of October 21, 2008. Workloads were run under multiple z/OS V1R8 images based on average LPAR profile of client systems. In this environment, the Mixed Workload consists of an equal mix of OLTP-T, OLTP-W, WASDB, and CB-L; the Low I/O (LoIO) Content Mix Workload consists of a mix of 44% CB-L, 28% WASDB and 28% OLTP-W; the Transaction Intensive (TI) Mix Workload consists of a mix of 20% CB-L, 40% OLTP-W, and 40% OLTP-T.

Note: Please contact your IBM marketing representative to insure that you are using the most current data. Proper use of this data requires an understanding of the LSPR measurement methodology.

*MSUs are used for software pricing and are not necessarily a direct indication of relative processor capacity. MSUs for the 2084, 2086, 2094, 2096 and 2097 model types are set to provide improved software price/performance for applicable programs which have MSU based pricing.

**PCI stands for Processor Capacity Index. The PCI values were calculated by multiplying the LSPR Mixed column by a common scaling factor associated with a particular LSPR table. Note the values appearing here were generated using zPCR so the full precision of each ITRR ratio is represented.
