Introduction Detailed hp rp7405/rp7410 Description In the single nPartition case, if two cells are present, either cell may be the root cell, assuming the both cells have MP Core I/O functionality present. If only one cell is present, that cell is the root cell (and should be cell 1). In the dual nPartition case (two cells required), each nPartition consists of one cell, and each cell must be a root cell. The ability to interconnect two cells in one nPartition or isolate the cells in a dual nPartition system provides system configuration flexibility. System partitioning is configured by the system management processor. Internal Disk Devices for hp rp7405/rp7410 As Figure 1-4 shows, in an hp rp7405/rp7410 cabinet the top internal disk drives connect to cell 1 through the MP Core I/O for cell 1 (for 1/0/0/3/0.6) and the LAN/SCSI card in slot 1_8 (I/O chassis 1 slot 8, for 1/0/1/0/0/1/1.6). Both of the bottom disk drives (0/0/0/3/0.6 and 0/0/0/3/0.5) connect to cell 0 through the MP core I/O for cell 0. A CD/DVD-ROM drive or DAT drive connects to cell 1 through the core I/O card for cell 1, thus it can be accessed through the cell 1 nPartition only.
