Superdome servers can be populated with Itanium 2 CPUs. It is no longer necessary to pay for the additional CPUs until the
customer uses them. However with HP's iCOD the remaining 2 CPUs that would cause the cell board to become fully
populated can be installed and remain idle. The additional CPUs can be activated instantly with a simple command
providing immediate increases in processing power to accommodate application traffic demands.
In the unlikely event that a CPU fails, the HP system will replace the failed CPU on the cell board at no additional charge.
The iCOD CPU brings the system back to full performance and capacity levels, reducing downtime and ensuring no
degradation in performance.
When additional capacity is required, additional CPUs on a cell board can be brought online. The iCOD CPUs are
activated with a single command.
CPU Instant Capacity on Demand (iCOD) 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.
