HP Instant Capacity for HP Integrity Superdome 2 Servers

3
HP Superdome 2 blades come with both sockets fully populated. An iCAP blade is one which has two
iCAP quad-core processors that is eight iCAP processor cores. RTU is available at a processor-level
that is four cores at a time. However, once a processor RTU is purchased, the four cores can be
turned on one or all at a time. Due to the dynamic nature of iCAP, the cores turned on are not limited
to one processor.
Memory on an iCAP cell blade can be all active or all iCAP. All iCAP memory must be turned on
at the same time by purchasing sufficient RTUs. Active memory on an inactive blade is always
fully accessible.
HP Temporary Instant Capacity
TiCAP is a prepaid block of processing time that allows iCAP cores to be turned on and off. This
capability is available only for cores and not for memory. TiCAP can be used on any system that
contains iCAP cores.
TiCAP is purchased as a 30 processing-day block, which provides 43,200 minutes of actual
activation time per core. For example, with one TiCAP block, one core can be activated for
30 days or two cores can be activated for one hour a day for 360 days. Usage is measured in
30-minute increments.
TiCAP minutes purchased can be applied on any partition. TiCAP minutes can also be distributed
over multiple partitions within a server. TiCAP applies to all iCAP cores within a partition.
Figure 1 shows the use of TiCAP in a system for which two temporary capacity blocks
(60 processing-days) have been purchased.

TiCAP includes temporary hardware support and a temporary HP-UX Operating Environment (OE) license.
