2.Architecture

The SDS2 Server Board is a monolithic printed circuit board that can accept two Intel® Pentium®

IIIprocessors using the Socket 370 FCPGA2 package. The SDS2 Server Board complies with the Entry SSI version 1.0 and ATX version 2.03 (12 inch x 13 inch) form-factor. It is designed around the Server Works* ServerSet* III HE-SL chipset.

The chipset contains three components:

∙The HE-SL CNB20 North Bridge provides an integrated memory controller

∙The CIOB20 I/O Bridge provides the interface for two peer 64-bit, 66 MHz PCI busses

∙The CSB5 South Bridge provides the LPC bus for legacy support.

The Server Board also contains other embedded devices such as:

∙2D/3D graphics accelerator

∙Two 10/100 Network Interface Controller

∙Dual channel Ultra160 SCSI

∙Standard I/O

∙Server management

The SDS2 Server Board provides six DIMM sockets for a maximum memory capacity of 6 GB. Only registered PC-133 compliant Registered SDRAM memory modules are supported. The current tested memory listing is posted on the Intel technical support web site: http://support.intel.com/support/motherboards/server/SDS2/
