∙SSD advantage (support of SSD drives)

2.1Detailed Information

2.1.1Intel Xeon Processor 5500 and 5600 Series

Intel Xeon processor 5500 and 5600 series are the latest generation Intel processors for two-socket servers. Based on a new 45nm die technology, they use integrated memory controllers on the processor itself rather than a separate memory controller. QuickPath interconnect technology, the speed of which varies with the processor model, replaces the familiar front-side bus.

Other Intel technologies used include:

•Intel Hyper-Threading, which enables more software threads to be running simultaneously.

•Intel Intelligent Power, which scales server power consumption to performance needs.

•Intel Turbo Boost, which boosts frequency for active cores by up to 400 MHz for during peak demand periods.

2.1.2Intel 5500 Chipset

Although the chipset supports up to 18 DIMMs, the PowerEdge R510 is designed with 8 DIMM slots. For more information on the Intel 5500 chipset, see Section 8,

2.2Sparing

Intel has added sparing back with Xeon processor 5600 series. In sparing mode, you must have identical memory in Channel_0, Channel_1 and Channel_2. For the R510, memories are installed in A1, A2 and A3 to enable the sparing mode. With sparing mode is enabled, usable memory capacity is 2/3 of the physical memory installed.
