13The z10 EC hardware model numbers (E12, E26, E40, E56and E64) on their own do not indicate the number of PUswhich are being used as CPs. For software billing pur-poses only, there will be a Capacity Indicator associatedwith the number of PUs that are characterized as CPs. Thisnumber will be reported by the Store System Information(STSI) instruction for software billing purposes only. Thereis no affinity between the hardware model and the numberof CPs. For example, it is possible to have a Model E26which has 13 PUs characterized as CPs, so for softwarebilling purposes, the STSI instruction would report 713.z10 EC model upgradesThere are full upgrades within the z10 EC models andupgrades from any z9 EC or z990 to any z10 EC. Upgradeof z10 EC Models E12, E26, E40 and E56 to the E64 isdisruptive. When upgrading to z10 EC Model E64, unlikethe z9 EC, the first book is retained. There are no directupgrades from the z9 BC or IBM eServer zSeries 900(z900), or previous generation IBM eServer zSeries.IBM is increasing the number of sub-capacity engines onthe z10 EC. A total of 36 sub-capacity settings are avail-able on any hardware model for 1-12 CPs. Models with 13CPs or greater must be full capacity.For the z10 EC models with 1-12 CPs, there are fourcapacity settings per engine for central processors (CPs).The entry point (Model 401) is approximately 23.69% ofa full speed CP (Model 701). All specialty engines con-tinue to run at full speed. Sub-capacity processors haveavailability of z10 EC features/functions and any-to-anyupgradeability is available within the sub-capacity matrix.All CPs must be the same capacity setting size within onez10 EC.z10 EC Model Capacity IDs:• 700, 401 to 412, 501 to 512, 601 to 612 and 701 to 764• Capacity setting 700 does not have any CP engines• Nxx, where n = the capacity setting of the engine, andxx = the number of PU characterized as CPs in the CEC• Once xx exceeds 12, then all CP engines are full capacityz10 EC Base and Subcapacity Offerings• The z10 EC has 36 additional capacity settings at thelow end• Available on ANY H/W Model for 1 to 12 CPs.
