The feature codes are calculated automatically when the CPE offering is configured. Whether
using the eConfig tool or the Resource Link, a target configuration must be ordered consisting
of a model identifier, a number of speciality engines, or both. Based on the target
configuration, a number of feature codes from the previous list are calculated automatically,
and a CPE offering record is constructed.
CPE is intended to replace capacity lost within the enterprise because of a planned event,
such as a facility upgrade or system relocation. CPE is intended for short duration events that
last up to a maximum of three days. Each CPE record, after it is activated, gives you access
to dormant PUs on the server for which you have a contract (as described by the feature
codes listed).
PUs can be configured in any combination of CP or specialty engine types (zIIP, SAP, IFL,
and ICF). At the time of CPE activation, the contracted configuration is activated. The general
rule of two zIIPs for each configured CP is maintained for the contracted configuration.
The processors that can be activated by CPE come from the available unassigned PUs on
any installed CPC drawer. CPE features can be added to an existing z13s server
non-disruptively. A one-time fee is applied for each individual CPE event, depending on the
contracted configuration and its resulting feature codes. Only one CPE contract can be
ordered at a time.
The base z13s configuration must have sufficient memory and channels to accommodate the
potential requirements of the large CPE configuration. It is important to ensure that all
required functions and resources are available on the z13s server where CPE is activated,
including coupling facility (CF) LEVELs for CF partitions, memory, cryptographic functions,
and connectivity capabilities.
The CPE configuration is activated temporarily, and provides extra PUs in addition to the
amount the z13 server had installed as its original, permanent configuration. The number of
additional PUs is predetermined by the number and type of feature codes configured, as
described by the list of the feature codes. The number of PUs that can be activated is limited
by the unused capacity that is available on the server.
When the planned event is over, the server must be returned to its original configuration. You
can deactivate the CPE features at any time before the expiration date.
A CPE contract must be in place before the special code that enables this capability can be
installed. CPE features can be added to an existing z13s server non-disruptively.
