HP Integrity rx7640 and HP 9000 rp7440 Servers Installation Guide

On the server, each nPartition has its own dedicated portion of the server hardware which can
run a single instance of the operating system. Each nPartition can boot, reboot, and operate
independently of any other nPartitions and hardware within the same server complex.
The server complex includes all hardware within an nPartition server: all cabinets, cells, I/O chassis,
I/O devices and racks, management and interconnecting hardware, power supplies, and fans.
A server complex can contain one or two nPartitions, enabling the hardware to function as a single
system or as multiple systems.
NOTE: Partition configuration information is available at the following website:

For details, see the nPartition Administrator's Guide.
