Re the comment: How prevalent are installations today where the CPs run at top speed, in other words at the same speed as zIIP engines? In other words, Is it that valid to assume equal speed processors? Clearly guidelines for lower zIIP utilization matter more when there is a difference, as offloading any zIIP work to a slower CP would elongate processing and response time, even if there is no delay waiting for a processor.
For any given Z system, the 'speed' (GHz) is always the same for all types to (PUs) processing units (CPs, IFLs, zIIPs, ICFs, IFP and SAP). In case of CPs, these can be different 'sub capacity settings' All the rest are always full capacity setting. Speed is always the same. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
