Functional Architecture Intel® Server Boards S5000PSL and S5000XSL TPS

Revision 1.7

Intel order number: D41763-008

 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.

3.1.3.4.2.3 Dual-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.

3.1.4 Snoop 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.

3.2 Enterprise 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
