Executive summary
HP Instant Capacity (iCAP) provides the capability to quickly add processor, memory, and cell board
capacity when needed while paying only a fraction of the cost for it until it is used.
HP Temporary Instant Capacity (TiCAP) provides pre-purchased processing time which can be used to
turn processor cores on and off as needed.
HP Global Instant Capacity (GiCAP) allows customers to share Instant Capacity usage rights among a
group of servers, enabling more cost-effective high-availability servers, more efficient use of data
center resources, and more flexibility in resource utilization.
Together, Instant Capacity, Temporary Instant Capacity, and Global Instant Capacity enhance system
agility and flexibility to support the Adaptive Enterprise.
