Introduction

Detailed hp rp7405/rp7410 Description

13

This concept allows maximum connectivity for mainstream 5V-only, 33 MHz, 32 bit (PCI-1x) and 64-bit
(PCI-2x) cards, as well as full I/O bandwidth utilization through the use of 64-bit, 66 MHz (PCI-4x) universal
cards.

MP/SCSI MP Core I/O Board

The hp rp7405/rp7410 accommodates two sets of MP Core I/O functionality. Each MP Core I/O board set
consists of a MP/SCSI board and a Procurium LAN/SCSI board. At least one MP/SCSI board is required
(independent of partitions) An additional MP/SCSI board can be added as well (and is required in a dual
partition system). Both MP/SCSI boards are oriented vertically and plug into the system backplane. The
MP/SCSI board incorporates a dual Ultra160 SCSI controller and is hot pluggable.

Procurium LAN/SCSI Board

At least one Procurium LAN/SCSI board is required for the minimum system configuration; two are required
in a dual partition system. The Procurium board is a standard PCI form factor card with PCI card edge
connectors. The PCI backplane has one slot location reserved for the required Procurium board and another
that can accommodate either a Procurium board or any other supported add-in PCI card. The Procurium
board is hot pluggable.
