Intel® Server Boards S5000PSL and S5000XSL TPS

Design and Environmental Specifications

3.1.3.4.2.2Dual Branch Mode Sparing

Dual branch mode sparing requires that all eight DIMM sockets be populated and must comply with the following population rules.

ƒDIMM_A1 and DIMM_B1 must be identical in organization, size and speed.

ƒDIMM_A2 and DIMM_B2 must be identical in organization, size and speed.

ƒDIMM_C1 and DIMM_D1 must be identical in organization, size and speed.

ƒDIMM_C2 and DIMM_D2 must be identical in organization, size and speed.

ƒDIMM_A1 and DIMM_A2 need not be identical in organization, size and speed.

ƒDIMM_B1 and DIMM_B2 need not be identical in organization, size and speed.

ƒDIMM_C1 and DIMM_C2 need not be identical in organization, size and speed.

ƒDIMM_D1 and DIMM_D2 need not be identical in organization, size and speed.

ƒSparing should be enabled in BIOS setup.

ƒThe BIOS will configure Rank Sparing Mode.

ƒThe larger of the pairs {DIMM_A1, DIMM_B1}, {DIMM_A2, DIMM_B2},

{DIMM_C1, DIMM_D1}, and {DIMM_C2, DIMM_D2} are selected as the spare pair units.

3.1.4Snoop Filter (5000X MCH only)

The 5000X version of the MCH includes a snoop filter. Depending on the application of the server, this feature can be used to enhance the performance of the server by eliminating traffic on the snooped system bus of the processor being snooped. By removing snoops form the snooped bus, the full bandwidth is available for other transactions.

3.2Enterprise South Bridge (ESB2-E)

The ESB2-E is a multi-function device that provides four distinct functions: an I/O controller, a PCI-X* bridge, a GB Ethernet controller, and a baseboard management controller (BMC). Each function has its own set of configuration registers. Once configured, each appears to the system as a distinct hardware controller.

The ESB2-E provides the gateway to all PC-compatible I/O devices and features. The server boards use the following ESB2-E features:

ƒPCI-X bus interface

ƒSix-channel SATA interface with SATA Busy LED Control

ƒDual GbE MAC

ƒBaseboard Management Controller (BMC)

ƒSingle ATA interface, with Ultra DMA 100 capability

ƒUniversal Serial Bus 2.0 (USB) interface

ƒRemovable media drives

ƒLPC bus interface

ƒPC-compatible timer/counter and DMA controllers

ƒAPIC and 8259 interrupt controller

ƒPower management
