Global Instant Capacity (GiCAP) allows hardware usage rights to be shared among servers, allowing resources to be deactivated in one system and activated in another to meet changing system demands. GiCAP can help protect your mission-critical environment by making it more cost-effective to implement high availability systems. With GiCAP, usage rights for hardware resources (processors, cell boards and memory) in a system that becomes unavailable (either planned or unplanned) can be released and used to activate resources in another Instant Capacity server.
