Please note that when ordering active sx1000 cell boards, Temporay Instant Capacity and non-Temporay
Instant Capacity processors and non-Instant Capacity memory can be ordered. But when ordering
Temporay Instant Capacity sx1000 cell boards, only Instant Capacity processors and Instant Capacity
memory can be ordered.
The following applies to CPU Instant Capacity on Superdome servers:
The number of Instant Capacity processors is selected per partition instead of per system at
planning/order time.
At least one processor per cell in a partition must be a purchased processor.
Processors are deallocated by Instant Capacity in such a way as to distribute deallocated
processors evenly across the cells in a partition. There is no way for a Customer Engineer (CE) or
an Account Support Engineer (ASE) or a customer to influence this distribution.
Reporting for the complex is done on a per partition basis. In other words, all partitions with Instant
Capacity processors must be capable of and configured for sending e mail to HP.
Processors can be allocated and deallocated instantly or after a reboot at the discretion of the user.
A license key must be obtained prior to either activating or deactivating Instant Capacity
processors. A free license key is issued once email connectivity with HP has been successfully
established from all partitions with Instant Capacity processors.
Performance Considerations with CPU Instant Capacity:
Going from one to two to three active CPUs on a cell board gives linear performance improvement
Going from three to four active CPUs gives linear performance improvement for most applications
except some technical applications that push the memory bus bandwidth.
Number of active CPUs per cell boards should be balanced across partitions. However, minor
differences are okay (example: four active CPUs on one cell board and three active CPUs on the
second cell board).
Note that the Instant Capacity software will do CPU activation to minimize differences of number of
active CPUs per cell board within a partition.

Cell Board ICAP
With cell board ICAP, Superdome servers can be populated with Itanium 2 cell boards (CPU and
memory) and it is no longer necessary to pay for the additional cell boards (CPU and memory) until the
customer uses them. Additional CPUs and cell boards can be activated instantly with a simple command
providing immediate increases in processing power and memory capacity to accommodate application
traffic demands.
In the unlikely event that a cell board fails, the HP system will replace the cell board at no additional
charge. The ICAP cell board brings the system back to full performance and capacity levels, reducing
downtime and ensuring no degradation in performance.
Please note the following when when ordering Instant Capacity sx1000 cell boards:
only Instant Capacity processors and Instant Capacity memory can be ordered.
the maximum memory needed must be ordered because it is not possible to purchase additional
Instant Capacity memory without ordering the Instant Capacity Cell Board upgrade product,
A9913A.
When additional capacity is required, additional cell boards can be brought online. The ICAP cell boards
are each activated with a single command.
Cell board Capacity on Demand (ICAP) can be ordered pre installed on Superdome servers. All cell
boards within the Superdome server will be populated with two or four CPUs and the customer orders the
number of CPUs that must be activated prior to shipment.
