CPU Mixing Support HP Superdome 2's governing rules for mixing processors is as follows: • Does not support mixing of processor families within an nPartition • Does not support processors running at different frequencies or different cache sizes within the same nPartition • Processor modules on the same blade must be the same revision, frequency, and cache size. HP Superdome 2 Memory Support HP Superdome 2 memory is not backwards compatible with the DDR DIMMs used on sx2000 Superdome based platforms. The following DIMM types are supported at initial release: • 4GB DIMM: 36 1Gb (x4) planar, 1 rank, 30.5mm height Only DIMMs that HP has qualified on the HP Superdome 2 are supported in HP Superdome 2 products. Installing an unsupported DIMM will not necessarily 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. DIMMs are populated in sets of 8 per blade. Interleaved memory works best with powers of 2, especially for larger amounts of memory. If the configuration has a large amount of memory and is not a power of 2, some of the memory may need to be configured as socket local memory. Sample Procedure for Creating nPartitions After the HP Superdome 2 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 nPartition(s). The following steps demonstrate an example of how you can create nPartitions for HP Superdome 2 using the OA CLI. 1. Log into the OA CLI and run parstatus to view the list of nPartition assignable resources. For example: Consider a 4 blade complex with 2 IOX enclosures.

CPU Mixing Support
HP Superdome 2's governing rules for mixing processors is as follows:
•
Does not support mixing of processor families within an nPartition
•
Does not support processors running at different frequencies or different cache sizes within
the same nPartition
•
Processor modules on the same blade must be the same revision, frequency, and cache size.
HP Superdome 2 Memory Support
HP Superdome 2 memory is not backwards compatible with the DDR DIMMs used on sx2000
Superdome based platforms. The following DIMM types are supported at initial release:
•
4GB DIMM: 36 1Gb (x4) planar, 1 rank, 30.5mm height
Only DIMMs that HP has qualified on the HP Superdome 2 are supported in HP Superdome 2
products. Installing an unsupported DIMM will not necessarily 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. DIMMs are populated in sets of 8 per blade.
Interleaved memory works best with powers of 2, especially for larger amounts of memory. If
the configuration has a large amount of memory and is not a power of 2, some of the memory
may need to be configured as socket local memory.
Sample Procedure for Creating nPartitions
After the HP Superdome 2 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
nPartition(s). The following steps demonstrate an example of how you can create nPartitions for
HP Superdome 2 using the OA CLI.
1.
Log into the OA CLI and run
parstatus
to view the list of nPartition assignable resources.
For example: Consider a 4 blade complex with 2 IOX enclosures.
When you run the

command, the following output is displayed.
