The following figure shows the typical workstation system board block diagram. Figure 1-1 System board block diagram NOTE: The x1, x4, x8, and x16 designators describe the number of electrical PCIe lanes routed to an expansion slot. For example, x16(8) means that the expansion slot is mechanically a x16 length connector, with eight PCIe lanes connected. Processor technology This workstation uses the Intel® 5520 chipset to support the latest Quad Core Intel® Xeon™ processor 5500 Series, including processors up to 95W. These processors incorporate an integrated 3-channel memory controller, microarchitecture improvements, and large L3 cache to provide superior performance. In addition, the workstation uses Intel QuickPath Interconnect (QPI) to connect the processors and I/O controller with speeds up to 6.4 GT/s. Memory technology Workstation dual in-line memory modules (DIMMs) are based on DDR3 1333MHz technology, and are error checking and correcting (ECC)-protected. Six direct-attach memory channels-three per central processing unit (CPU)-enable low latency accesses and fast data transfer for improved performance. Configurations with one processor provide access to three DIMM slots, while the addition of a second processor provides access to three more DIMM slots, supporting a total system memory size up to 24GB (using 4GB DIMMs). 2 Chapter 1 Workstation overview ENWW
