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 at initial release: • 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 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. parstatus NOTE: No action specified. Default behavior is display all. [Complex] Complex Name: Complex1 Complex UUID: FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF Complex Capacity Compute Enclosure: 1 IO Enclosure: 8 Monarch OA Location: 1 Model: N/A Original Serial Number: Unset Current Product Order Number: AH337A OEM Manufacturer: N/A Total number of partitions present: 0 nl nl nl nl nl nl nl nl nl nl nl nl nl nl nl nl nl nl nl nl nl nl nl Sample procedure for creating nPartitions 35
