IBM 46K7791 server / storage / networking hardware Server Hardware / Parts

The IBM 46K7791 is a 4-way, 4.2GHz POWER6 system board for the 8203-E4A (Power 520) server, sold as the direct sibling to 46K7790 in IBM’s system-board pairing for this chassis. It carries the four processor sockets and supporting logic for a fully populated 520, distinct from the lower-density 1-way and 2-way boards used in smaller configurations of the same machine. The 8203-E4A was one of IBM’s volume entry POWER6 servers, running AIX, IBM i and Linux workloads in small and mid-size data centres through the POWER6 generation, and boards like this remain in demand for extending or repairing existing 520 deployments rather than new builds. Tech-Star is UK-based and ships worldwide. Buyers should confirm firmware level compatibility with their existing 8203-E4A configuration, since system boards of this generation are matched to specific microcode releases.
