Configuration Configuration Guidelines Table D-1, hp Integrity Superdome or hp 9000 Superdome SD64 Partition Configurations, shows configurations that yield the best performance. However, memory may be left over. This memory is interleaved in the 16-entry tables and does not always yield the best performance. Depending on the memory configuration and the partition size the memory system performance will always increase, although not always linearly. Use the following guidelines when building partitions: • Build the largest partition first. • Keep partitions with four cells or less on the same quad. (Slots 0-3, 4-7, 8-11, and 12-15) • Keep the amount of memory on each cell in a partition as equal as possible. • Fill empty cabinets before adding to a partially populated cabinet. • For best performance, partitions should be either single cell or greater powers of 2: 2, 4, 8, and 16 cells. • Always check a new partition for bottlenecks with the formula Qx*Qy/Qt/I.
