Functional Architecture

Intel® Server Boards S5000PSL and S5000XSL TPS

DIMM_C1 and DIMM_C2 need not be identical in organization, size, and speed.

DIMM_D1 and DIMM_D2 need not be identical in organization, size, and speed.

Sparing should be enabled in the BIOS setup.

The BIOS will configure Rank Sparing Mode.

The 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.

3.1.3.4.2.3Dual-Ranked DIMM Sparing

When a dual-ranked FBDIMM is used as a spare, the BIOS has the ability to independently select a physical rank on that FBDIMM as the spare unit and utilize the other physical rank as a normal unit. This selective sparing ensures maximization of available memory while still providing RAS. However, populating differently-ranked FBDIMMs for sparing is not a good practice and may yield unpredictable results.

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 from 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:

PCI-X bus interface

Six-channel SATA interface with SATA Busy LED Control

Dual GbE MAC

Baseboard Management Controller (BMC)

Single ATA interface, with Ultra DMA 100 capability

Universal Serial Bus 2.0 (USB) interface

Removable media drives

LPC bus interface

PC-compatible timer/counter and DMA controllers

APIC and 8259 interrupt controller

Power management

System RTC

General purpose I/O

This section describes the function of most of the listed features as they pertain to these server boards. For more detailed information, see the Intel® S5000 Server Board Family Datasheet or the Intel® 631xESB/632xESB I/O Controller Hub Datasheet.
