Cells and nPartitions An nPartition comprises one or more cells working as a single system. Any I/O chassis that is attached to a cell belonging to an nPartition is also assigned to the nPartition. Each I/O chassis has PCI card slots, I/O cards, attached devices, and a core I/O card assigned to the I/O chassis. 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 more nPartitions, enabling the hardware to function as a single system or as multiple systems. NOTE: Partition configuration information is available on the Web at: http://docs.hp.com. Refer to HP System Partitions Guide: Administration for nPartitions for details.

Cells and nPartitions
An nPartition comprises one or more cells working as a single system. Any I/O chassis that is
attached to a cell belonging to an nPartition is also assigned to the nPartition. Each I/O chassis
has PCI card slots, I/O cards, attached devices, and a core I/O card assigned to the I/O chassis.
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 more nPartitions, enabling the hardware to function as a
single system or as multiple systems.
