Maximum Number of Virtual Partitions
The maximum number of virtual partitions is the number of CPUs given
the following limitations:
• Because the I/O combo cards are not supported for boot disks and if
you require a network interface for each virtual partition, the
maximum number of virtual partitions for the rp7400/N4000 is 7.
Given that each virtual partition requires 2 PCI slots (one SCSI or
FC card and one LAN card) and each rp7400/N4000 has 12 external
PCI slots, this provides a maximum of 6 partitions. The core I/O
provides for one boot disk and one LAN port, which provides for an
additional 1 partition, resulting in a maximum of 7 partitions.
• The maximum number of virtual partitions within a single
nPartition is 8.
Server Number of Partitions
rp5470/L3000 up to 2 partitions
rp7400/N4000 up to 4 partitions
