Global Instant Capacity Grouping Rules

A GiCAP group consists of a list of server complexes that are allowed to share Instant Capacity usage rights (for cores, cell boards, and memory) and temporary capacity. Other than performance considerations, there are no particular constraints on the number of servers allowed in a group, but there are grouping rules defined by HP to specify the types of servers allowed to group together.

NOTE: The Instant Capacity installation does not include a default grouping rules file. Grouping rules must be downloaded from the HP Utility Pricing Solutions portal:

http://www.hp.com/go/icap/portal

Grouping rules are defined according to server class. The price structure of usage rights is also based on server class. Since GiCAP pools usage rights, these usage rights can be used on any type of server, regardless of the server class for which they were originally purchased. Therefore, grouping rules were created to define the classes of servers allowed to share usage rights.

Use the icapmanage -Rcommand to view the hardware grouping information. When used in combination with a list of host names, this command reports all hardware types with which the hosts might be grouped. If the hosts are not compatible with each other, no hardware is reported. Without a list of host names, this command reports all supported hardware and grouping rules.

Under some circumstances you might need to acquire newer grouping rules from the portal (for example, when adding new hardware not previously covered by the grouping rules currently in use). Install the encrypted rules file on the Group Manager system using the icapmanage -icommand. The icapmanage -Rcommand shows the version number of the grouping rules installed, and when you download a new grouping rules file use icapmanage -R-Uto compare the version and supported systems before deciding to install the new grouping rules.

The following command installs a grouping rules file, retrieved from the portal, on the Group Manager system:

> icapmanage -i -U FSTL012234_gicap.encrypt
