IBM eServer Bladecenter HS20 8678

IBM eServer Bladecenter HS20 8678 ... command are powerful, two-way SMP capable Intel Xeon processors, high-speed memory, gigabit Ethernet controllers, and advanced high-availability and systems management features. Best of all, it provides a new economic approach to the deployment of large numbers of powerful servers using reduced space and power resources.

This flip-chip, pin grid array 2 (FC-PGA2) processor features advanced transfer L2 cache that is integrated onto the processor core and run at the same clock speed as the processor core. The advanced transfer cache is a result of a "backside bus" that is 256 bits wide. It features a quad-wide cache line that can transfer four 64-bit cache line segments at one time to deliver full-speed capability. The cache is eight-way set associative.

Two Intel Xeon connectors are standard on the blade board to support installation of a second processor. High-speed, DDR SDRAM is synchronized for up to 400MHz processor-to-memory subsystem performance with current processors.
