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 on the Web at: http://docs.hp.com Refer to HP System Partitions Guide: Administration for nPartitions for details. Internal Disk Devices for the Server As Figure 1-10 shows, in a server cabinet, the top internal disk drives connect to cell 1 through the core I/O for cell 1. Both of the bottom disk drives connect to cell 0 through the core I/O for cell 0. The DVD/DAT drive connects to cell 1 through the core I/O card for cell 1.
