Global Instant Capacity Overview

Global Instant Capacity, or GiCAP, provides you with the flexibility to move usage rights for Instant Capacity components within a group of servers. It also provides “pooled” temporary capacity across the group. This has several potential benefits: cost-effective high availability, more adaptable load balancing, and more efficient and easier use of temporary capacity. A GiCAP Group is managed using the icapmanage command.

Global Instant Capacity provides several benefits:

•Cost-effective high availability. In case of planned or unplanned down time, you can transfer usage rights from a failed partition or a failed member complex to one or more other servers in the group that are providing backup availability. Without GiCAP, the only way to provide this failover scenario is to provision each server with an adequate amount of temporary capacity.

•Load balancing. To provide adaptability and to accommodate changing demands, usage rights can be transferred between servers in a group. For example, a server with extra, unused capacity can release usage rights to activate additional components on an overloaded server that needs extra capacity.

•Pooled temporary capacity. Temporary capacity usage rights can be shared across servers for better efficiency and ease of use. By pooling temporary capacity, there is less need to provision temporary capacity for each server.

Global Instant Capacity is part of Instant Capacity version 8.x and later on HP-UX systems, and is enabled by purchasing a special GiCAP sharing rights codeword. After purchase, the codeword can be retrieved from the HP Utility Pricing Solutions web portal:

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

When you retrieve the codeword, you must provide the sales order number for the codeword purchase, the serial number of the Group Manager system, and partition information for the Group Manager. Applying this codeword on a system running Instant Capacity enables the creation of a GiCAP group with members.

Figure 7-1illustrates the process of configuring and using Global Instant Capacity.
