HP Integrity rx8640 and HP 9000 rp8440 Server Overview
Detailed Server Description
Core I/O Card
Up to two core I/O cards can be plugged into the server. Two core I/O cards enable two I/O partitions to exist
in the server. The server can have up to two partitions. When a Server Expansion Unit with two core I/O
cards is attached to the server, two additional partitions can be configured.
A core I/O card can be replaced with standby power applied. The system power to the core I/O is handled in
the hardware the same way a hot-plug PCI/PCI-X card is handled. Standby power to core I/O is handled by
power manager devices to limit inrush current during insertion.
Mass Storage (Disk) Backplane
Internal mass storage connections to disks are routed on the mass storage backplane, which has connectors
and termination logic. All hard disks are hot-plug but removable media disks are not hot-plug. The server
accommodates two internal, removable media devices. Power connectors for removable media devices are on
the mass storage backplane. For more information, refer to Figure 1-13.
