In compact 1U and 2U form factors, the Sun Fire X4170, X4270, and X4275 servers combine the power of a new

generation of Intel Xeon processors with Sun?s system engineering expertise. Based on Sun?s Open Network

System design approach, these servers offer the needed performance, density, and expandability to satisfy

demanding datacenter applications, especially for virtualization and consolidation initiatives. This white paper

describes the architecture of the Sun Fire X4170, X4270, and X4275 servers, including the processor technology, I/O

subsystem, built-in system management features, and range of supported operating systems.
