CPU mixing support
The following are the rules for mixing processors in Superdome 2:
• Mixing of processor families within an nPartition is not supported
• Processors running at different frequencies or different cache sizes within the same nPartition
are not supported
• The processor modules on a blade must have the same revision, frequency, and cache size.
HP Superdome 2 memory support
HP Superdome 2 memory is not backward compatible with the DDR DIMMs used on sx2000
Superdome based platforms. The following DIMM types are supported on CB900s i2 blades:
• 4GB DIMM: 36 1Gb (x4) planar, 1 rank, 30.5mm height
• 8GB DIMM: 27 2Gb (x4) planar, 2 rank, 30.5mm height
• 4GB and 8GB DIMMs cannot be mixed within the same blade
The following DIMM type is supported on CB900s i4 blades:
• 8GB LV DIMM: 36 1Gb (x4) planar, 2 rank, 30.5mm height
• The DIMMs supported on CB900s i2 blades are NOT supported on CB900s i4 blades and
vice versa
HP Superdome 2 supports DIMMs that are qualified by HP. Installing an unsupported DIMM will
not prevent the partition from booting and no caution or informational message is sent. However,
unsupported DIMMs will void the system's warranty.
The HP Superdome 2 blade supports 32 DIMMs, which are populated in sets of 4 per socket.
Interleaved memory works best with powers of 2, especially for larger memory sizes. If the
configuration has a large memory size and is not a power of 2, some of the memory might need
to be configured as socket local memory.
Sample procedure for creating nPartitions
After the HP Superdome 2 server is installed with the required hardware components and the
booting requirements are met, you can login through the OA CLI or the OA GUI and create the
nPartitions. To create nPartitions for HP Superdome 2 using the OA CLI:
1. Log into the OA CLI and run the parstatus command to view the list of nPartition assignable
resources.
For example: Consider a 4-blade complex with 2 IOX enclosures.
When you run the parstatus command, the following output is displayed.

NOTE: No action specified. Default behavior is display all.
