MP Core I/O Connections
Each HP Integrity rx7620 Server can have up to two MP core I/O board sets installed. This allows
for two partitions to be operating, or allows MP core I/O redundancy in a single partition
configuration. Each MP core I/O board set consists of two boards: the MP/SCSI board and the
LAN/SCSI board. The MP/SCSI board is oriented vertically and accessed from the back of the
server. The LAN/SCSI is accessed from the PCI expansion card bay. Only the primary MP core
I/O board set (MP/SCSI slot 1 and LAN/SCSI slot 8, chassis 1) is required for a single partition
implementation. The secondary MP/SCSI board is not necessary for full operation; however,
without the secondary MP/SCSI board, only two internal disks can be accessed.
MP/SCSI Connections
The MP/SCSI board is required to update firmware, access the console, turn partition power on
or off, access all but two of the internal peripherals, and utilize other features of the system.
Connections to the MP/SCSI board include the following:
