The HP 507795-B21 is an Intel Xeon L5530 quad-core processor designed for the ProLiant BL460c G6 blade server. Operating at 2.40GHz with 5.86GT/s QPI interconnect speed, this LGA1366 Socket-B CPU delivers 8MB L3 cache and 1MB L2 cache per core. Built on 45nm process technology, the L5530 consumes just 80W, making it ideal for power-constrained blade environments. This processor supports virtualization workloads, database operations, and general-purpose enterprise applications typical of mid-2000s ProLiant infrastructure. Compatible with other Xeon 5500 series processors in dual-socket G6 configurations, the L5530 offers cost-effective performance scaling for existing blade deployments.
