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).
