These servers are high-throughput, two-way SMP-capable Intel Xeon-based network servers with excellent scalability when you add memory and a second processor. They incorporate powerful 2.60 or 2.80GHz Intel Xeon processors with 512 KB advanced transfer L2 cache. These flip-chip, pin grid array 2 (FC-PGA2) processors feature advanced transfer L2 caches that are 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 system board to support installation of a second processor. High-speed, 266 MHz DDR SDRAM is optimized for 100MHz processor-to-memory subsystem performance. The xSeries 335 server uses the ServerWorks Grand Champion LE (GCLE) chipset to maximize throughput from processors to memory, and to a primary 32-bit and secondary 64-bit PCI buses. The two expansion slots are supported through the secondary 64-bit bus.
