HP 600737-L21 Intel Xeon E5503 2.0GHz Processor Kit DL320 G6

The HP 600737-L21 is a processor kit built around the Intel Xeon E5503, a dual-core chip from Intel's Nehalem-EP family clocked at 2.0GHz. Packaged as an L21 kit, it includes the processor along with the heatsink assembly matched to the HP ProLiant DL320 G6 chassis, making installation straightforward for IT staff maintaining existing server infrastructure. The 80W thermal design power keeps cooling demands reasonable, an important consideration in density-constrained rack environments.

With 4MB of L3 cache and two processing cores, the E5503 is positioned for lighter server duties — file and print services, basic web hosting, DNS, DHCP, or low-density virtual machine workloads. It is not intended for compute-intensive applications, but for organizations extending the service life of their DL320 G6 hardware, this kit provides a cost-effective way to maintain or modestly improve processing capability without replacing the entire server.
