IBM z13s Technical Guide
Capacity Provisioning
Manager (CPM) As a component of z/OS Capacity Provisioning, CPM monitors
business-critical workloads that are running on z/OS systems on z13s
CPCs.
Customer profile This information is on IBM Resource Link, and contains customer and
machine information. A customer profile can contain information about more
than one machine.
Full capacity CP
feature For z13s servers, capacity settings Z xx are full capacity settings.
High water mark Capacity purchased and owned by the customer.
Installed record The LICCC record was downloaded, staged to the Support Element (SE),
and installed on the CPC. A maximum of eight records can be concurrently
installed and active.
Licensed Internal
Code (LIC) LIC is microcode, basic I/O system code, utility programs, device drivers,
diagnostics, and any other code that is delivered with an IBM machine to
enable the machine’s specified functions.
LICCC Configuration control by the LIC provides for a server upgrade without
hardware changes by enabling the activation of extra, previously installed
capacity.
MES An upgrade process initiated through an IBM representative and installed by
IBM personnel.
Model capacity
identifier (MCI) Shows the current active capacity on the server, including all replacement
and billable capacity. For z13s servers, the model capacity identifier is in the
form of A
xx to Zxx, where xx indicates the number of active CPs. Note that
xx can have a range of 01-06.
Model permanent
capacity identifier
(MPCI) Keeps information about capacity settings that were active before any
temporary capacity was activated.
Model temporary
capacity identifier
(MTCI) Reflects the permanent capacity with billable capacity only, without
replacement capacity. If no billable temporary capacity is active, MTCI
equals MPCI.
On/Off CoD Represents a function that enables a spare capacity in a CPC to be made
available to increase the total capacity of a CPC. For example, On/Off CoD
can be used to acquire more capacity to handle a workload peak.
Feature on demand
(FoD) FoD is a new centralized way to flexibly entitle features and functions on the
system. FoD contains, for example, the zBX High Water Marks (HWM).
HWMs refer to highest quantity of blade entitlements by blade type that the
customer has purchased. On z196/z114, the HWMs are stored in the
processor and memory LICCC record. On zEC12, zBC12, z13, and z13s
servers, the HWMs are found in the FoD record.
Permanent capacity The capacity that a customer purchases and activates. This amount might
be less capacity than the total capacity purchased.
Permanent upgrade LIC licensed by IBM to enable the activation of applicable computing
resources, such as processors or memory, for a specific CIU-eligible
machine on a permanent basis.
CPC drawer Packaging technology that contains the single chip modules (SCMs) for the
processor units (PUs) and shared cache (SC) chips, and memory and
connections to I/O and coupling links.
