2. Architecture
The SDS2 Server Board is a monolithic printed circuit board that can accept two Intel
®
Pentium
®
III processors 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:
