2.5.9 Fibre 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.
2.5.10 RAID 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.
2.5.11 Power 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:
ƒ With two power supply modules installed, a fully configured system has (1+1) power
redundancy.
ƒ With 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
