number will be reported by the Store System Information
(STSI) instruction for software billing purposes only. There
is no affi nity between the hardware model and the number
of CPs. For example, it is possible to have a Model E26
which has 13 PUs characterized as CPs, so for software
billing purposes, the STSI instruction would report 713.
z10 EC model upgrades
There are full upgrades within the z10 EC models and
upgrades from any z9 EC or z990 to any z10 EC. Upgrade
of z10 EC Models E12, E26, E40 and E56 to the E64 is
disruptive. When upgrading to z10 EC Model E64, unlike
the z9 EC, the fi rst book is retained. There are no direct
upgrades 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 on
the z10 EC. A total of 36 sub-capacity settings are avail-
able on any hardware model for 1-12 CPs. Models with 13
CPs or greater must be full capacity.
For the z10 EC models with 1-12 CPs, there are four
capacity settings per engine for central processors (CPs).
The entry point (Model 401) is approximately 23.69% of
a full speed CP (Model 701). All specialty engines con-
tinue to run at full speed. Sub-capacity processors have
availability of z10 EC features/functions and any-to-any
upgradeability is available within the sub-capacity matrix.
All CPs must be the same capacity setting size within one
z10 EC.
z10 EC Model Capacity Identifi ers:
• 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, and
xx = the number of PU characterized as CPs in the CEC
•
Once xx exceeds 12, then all CP engines are full capacity
z10 EC Base and Sub-capacity Offerings
•
The z10 EC has 36 additional capacity settings at the low end
• Available on ANY H/W Model for 1 to 12 CPs. Models with 13
CPs or greater have to be full capacity
• All CPs must be the same capacity within the z10 EC
• All specialty engines run at full capacity. The one for one entitle-
ment to purchase one zAAP or one zIIP for each CP purchased
is the same for CPs of any capacity.
• Only 12 CPs can have granular capacity, other PUs must be
CBU or characterized as specialty engines
