Internal Disk Devices for HP rp7410 and rp8400 Servers

HP System Partitions Guide: Administration for nPartitions, rev 5.1

On both HP rp7410 and rp8400 servers, slots 1–7 are dual-rope slots,

which have two connections between the slot’s local bus adapter (LBA)

and the I/O chassis system bus adapter (SBA). The core I/O connections

(slot 0) and slot 8 are single-rope slots, which have a single connection

between the slot LBA and the I/O chassis SBA. The dual-rope slots can

have greater sustained bandwidth than single-rope slots.

Internal Disk Devices for HP rp7410

and rp8400 Servers

This section covers hardware paths and locations for the internal disk

devices in rp7410 and rp8400 servers:

Disk Devices in HP rp7410 Cabinets

The hardware paths for internal drives in an HP rp7410 cabinet are

shown in Figure 1-10.

Figure 1-10 HP rp7410 Internal Storage Hardware Paths

As Figure 1-10 shows, in an HP rp7410 cabinet the top internal disk

drives connect to cell 1 through the 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 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 cell 1’s nPartition only.
