3.4 Gigabit

Ethernet

A single Broadcom* BCM5704C controller provides the on-board Gigabit Ethernet interface.
This controller has two ports that can independently operate at 1000/100/10 Mbps and support
failover and teaming for greater reliability and performance. The two Media Access Controllers
support full-duplex and half-duplex modes at all speeds and have their own PCI configuration
space and on-chip memory for higher performance with load balancing and packet buffering.
For optimal performance, the controller is configured as a 64-bit PCI-X 133MHz device. The
ICH5 contains an Ethernet controller, but this device is not used by the Intel

®

Server Board Set

SE8500HW4.

3.5 Serial ATA (SATA)

The ICH5 provides a Serial ATA (SATA) interface with a transfer rate of up to 1.5GB/s. The
Intel

®

Server Board Set SE8500HW4 Mainboard has a standard 7-pin vertical connector for this

feature. SATA cables should be 1m (40 inches) or less in length.

3.6 Fibre Channel

The Intel

®

Fibre Channel Module seats into a custom-wired PCI Express x16 slot on the Intel

®

Server Board Set SE8500HW4 Mainboard, which is attached to the Intel

®

IOP332 Storage I/O

Processor. The module uses a Qlogic* ISP2322 FC-PCI-X controller and has the following
features:

ƒ

Two independent 2 Gbps Fibre Channel ports

ƒ

Support for Fibre Channel virtual interface (VI) protocol

ƒ

Automatically negotiates Fibre Channel bit rate (1 or 2 Gbps)

ƒ

Supports up to 400 MBps sustained Fibre Channel data transfer rate

ƒ

1 MB SRAM per port

ƒ

Data and code parity protection

ƒ

Host intervention not required to execute complete SCSI, IP, or VI operations

ƒ

LC-style optical connectors

ƒ

Works with the Qlogic SANsurfer* Management Suite and other Qlogic FC cards

®

Fibre Channel Module User Guide.

3.7 Firmware

Hubs

The Intel

®

Server Board Set SE8500HW4 Mainboard has a combined total of 4MB flash

memory that serves as the firmware hub (FWH) for the system BIOS. The system BIOS fits into
2MB of flash, but twice that is required to support the rolling BIOS feature. See Chapter 5 for
more information on the rolling BIOS.
