System Overview

Intel® Server Platform SR6850HW4 TPS

2.5.9Fibre Channel Module

The Server Board Set SE8500HW4 Mainboard supports the Intel Fibre Channel Module as a mass storage expansion option. The card is based on the Qlogic* ISP2322 FC PCI-X controller and plugs into a reversed PCI Express x16 slot on the Server Board Set SE8500HW4 Mainboard. See the Intel Fibre Channel Module Users Guide for descriptions of this board.

2.5.10RAID On Motherboard (ROMB)

The Server Board Set SE8500HW4 Mainboard supports a RAID On Motherboard (ROMB) solution via the Intel IOP332 storage I/O Processor in conjunction with the LSI Logic* 53C1030 SCSI controller. To enable this option the Intel RAID Activation Key and a DDR2 400MHz DIMM are required. The optional Intel RAID Smart Battery is also available to maintain the contents of the DIMM in the event of power loss. See the Intel RAID Smart Battery Technical Product Specification for a description of the ROMB solution.

2.5.11Power Supply Module

Two hot-swap power supply modules are installed side by side at the rear of the chassis. Each supply has its own AC input power connector and is rated at 1570W over an input range of 100-240 VAC.

The power subsystem is configured as follows:

ƒWith two power supply modules installed, a fully configured system has (1+1) power redundancy.

ƒWith one supply module installed, the system does not have redundant power but will still run a fully configured system.

Note: When only one power supply module is installed, the active fan module is required in the unpopulated power supply slot for proper system cooling.

One power supply module is capable of handling the maximum power requirements for a fully configured Server Platform SR6850HW4, which includes four processors, 64 GB of memory, seven PCI add-in cards, ten hot-swap hard disk drives, an optical drive, a Fibre Channel Module, ROMB options installed, and a SCSI tape device.

When two power supply modules are installed, the user can replace a failed power supply module without affecting the system functionality. Power supplies have three LEDs to identify failure, power good and AC OK.

The power subsystem receives AC power through two power cords. When two power supply modules and two power cords are installed, the system has (1+1) power cord redundancy and can be powered by two separate AC sources. In this configuration, the system will continue to function without interruption if one of the AC sources fails. See Chapter 5 for more information.

Note: The total power requirement for the Server Platform SR6850HW4 exceeds the 240 VA energy hazard limits that define an operator accessible area. As a result, only
