Overview of nPartitions
On HP’s nPartition servers, each nPartition is a “logical system” that has
its own dedicated portion of the server hardware that can run a single
instance of the HP-UX 11i operating system. Each nPartition can boot,
reboot, and operate independently of any other partitions and hardware
within the same server complex.
Each nPartition has one or more cells (containing processors and
memory) that are assigned to the partition for its exclusive use. Any
I/O chassis that is attached to a cell belonging to a partition also is
assigned to the partition. (Each chassis has PCI card slots plus any I/O
cards and attached devices, and may also have core I/O.)
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.
You can configure one or more nPartitions within a server complex,
allowing the hardware to function as a single HP-UX 11i system or as
many systems.
