The IBM BladeCenter LS22 blade server, coupled with the BladeCenter chassis, advance application serving with performance, density, and scalability.The IBM BladeCenter LS22 blade server is high-throughput, highly scalable, two-socket and four-socket, SMP-capable, AMD Opteron-based blade server. AMD Opteron processor cores support a 64 KB two-way set associative L1 instruction cache and a 64 KB two-way set associative L1 data cache. In addition, each core supports a 512 KB L2 cache that is 16-way set associative for both instruction and data. On a quad-core processor, each processing core contains an independent set of L1 and L2 caches.
