4.5 Capacity BackUp

Also available are three new Capacity BackUp features for configuring systems
used for disaster recovery. Capacity BackUp for IBM Sserver p5 590 and 595
systems offers an offsite, disaster recovery machine at an affordable price. This
disaster recovery machine has primarily inactive Capacity on Demand (CoD)
processors that can be activated in the event of a disaster. Capacity BackUp for
IBM eServer p5 offers configurations of either a 32-way server (28 inactive and 4
active processors) or a 64-way server (60 inactive and 4 active processors).
Capacity BackUp systems can be turned on at any time by using the On/Off CoD
activation procedure for the needed performance during an unplanned system
outage. Each Capacity BackUp configuration is limited to 450 On/Off CoD credit
days per processor book. For clients who require additional capacity or

Description
Provides a means of planned growth
for clients who know they will need
increased capacity but aren't sure
when
Provides for planned and unplanned
short-term growth driven by
temporary processing requirements
such as seasonal activity, period-end
requirements, or special promotions
Provides the flexibility to evaluate
how additional resources will affect
existing workloads, or to test new
applications by activating additional
processing power or memory
capacity (up to the limit installed on
the server) for up to 30 contiguous
days
Provides a means to purchase a
machine for use when off-site
computing is required, such as
during disaster recovery.
