Product Overview Overview: The rack-optimized Intel® Server Board S5500WB is designed for high-density computing environments where energy efficiency and total cost of ownership are critical. It supports up to two Intel® Xeon® processor 5500 series on next-generation Intel® microarchitecture, highly scalable DDR3 memory, and expandable PCIe 2.0 I/O. The Intel® Server Board S5500WB is offered in two models: 1. SSI SKU- this version of the server board is designed to work with an "off the shelf" multi-rail power supply that adheres to the SSI power specification: "Power Supply Design Guideline for 2008 Dual-Socket Servers and Workstations". SSI specifications can be viewed at the following web site: http://ssiforum.org 2. 12V SKU - this version of the server board uses specially designed "single rail" power supplies that provide 12V and 5V standby current. The server board has integrated high efficiency voltage regulators that produce other voltages required (e.g. 3.3V, 5V). The board can also supply 5V power needed for hard drives. More details on this can be found in the Technical Product Specification (TPS).
