Combining high-performance architecture with high-performance Xeon processors

•Large L2 cache — 9MB, 8MB, 6MB or 4MB of internal processor cache (model-specific)

•Large L3 cache — 16MB, 12MB, or 8MB of external processor cache (model-specific)

•Huge L4 cache — 256GB per chassis (up to 1GB in a 4-chassis configuration) of IBM-unique XceL4v Dynamic Server cache

•64-bit extensions (EM64T)

•Fast front-side buses — 4 x 1066MHz (one per processor)

•Fast memory — PC2-5300 DDR II ECC memory standard with two-way interleaving and a low-latency memory controller

•Embedded virtualization (in selected models)

•Fast disk technology — Integrated Serial-Attach SCSI (SAS) controller and slotless hardware-basedRAID-0 data striping
