Instant Capacity Software can move usage rights within a server because the usage rights are tracked locally in system inventory. In
order to track usage rights across a group of servers with Global Instant Capacity, a separate server called the GiCAP Group
Manager is required.

The Group Manager requires no connection to HP, and is used by the Customer to manage their GiCAP environment. The GiCAP
Group Manager creates groups, maintains information about the resources that members can exchange, and facilitates the
movement of usage rights between group members. The Group Manager does not have to be a dedicated server - the Customer
can use an existing server on site as long as it meets the Group Manager requirements:

can use an existing server on site as long as it meets the Group Manager requirements:
must be an HP-UX 11i or later nPar or vPar
must be running Instant Capacity Software version 8.x
must be able to communicate over the network to all group members

The Group Manager may be run on either a partitionable or non-partitionable system, but changing the configuration of the
partitions may result in the Group Manager becoming inoperative, so it is therefore recommended that the Group Manager be on a
non-partitionable server for optimal availability. It is also recommended that the Group Manager not run on a group member - both
for recoverability and ease of use. That is, the system should be independent of the group, but it does not need to be dedicated only
to the Group Manager software. The Group Manager system must have a machine-readable serial number, as displayed by the shell
command "getconf CS_MACHINE_SERIAL" and must run HP-UX 11i v1 or later. A management server fitting these requirements
could be used, such as the Superdome Support Management Station (SMS). The separate server used to provide quorum service for
the Serviceguard cluster could also potentially be used to host the Group Manager, or an HP Systems Insight Manager CMS.

iCAP version 9.x onwards supports the capability to have a standby group manager. If the primary group manager fails, GiCAP
operations can continue by activating the standby group manager.

NOTE:
NOTE: The Group Manager cannot run in an Integrity Virtual Machine (also known as a "guest"). This is because the GiCAP Group
Manager requires programmatic access to information to identify the serial number and partition information of where it is running.
This information is not available in a HPVM and thus the Group Manager can not be run in that environment.

The GiCAP Group Manager can manage any number of groups, as the number of groups on a Group Manager has no impact on

GiCAP is enabled via the purchase of GiCAP Sharing Rights. GiCAP Sharing Rights can be thought of as tokens which are
consumed by every iCAP processor core brought into a GiCAP Group. In order to bring a server into a GiCAP Group, there must be
at least as many tokens as there are iCAP processor cores within the server.

One GiCAP Sharing Right must be ordered for every Instant Capacity processor core in the entire complex, across all partitions. To
share iCAP cells with memory, a GiCAP Sharing Right should be ordered for every core on the iCAP cell. A server without any Instant
Capacity hardware will not consume any Sharing Rights and can enter a GiCAP Group without consuming any Sharing Rights to
deactivate resources and lend usage rights to other Group members.

GiCAP Sharing Rights are downloaded from the Utility Pricing Solutions Portal as Codewords using the same process as used for all
other Instant Capacity Codewords. The Codeword is applied to the GiCAP Group Manager system (not the individual Group
Members). Sharing Rights are owned by the server for which they are purchased, and expire when the server leaves the GiCAP
Group.

GiCAP Sharing Rights can be purchased for new servers as well as an add on to existing environments.
