A technique is disclosed for generating rebuild data of a RAID configuration having one or more failed drives. The RAID configuration includes multiple sets of drives coupled to respective computing nodes, and the computing nodes are coupled together via a network. A lead node directs rebuild activities, communicating with the other node or nodes and directing such node(s) to compute partial rebuild results. The partial rebuild results are based on data of the drives of the RAID configuration coupled to the other node(s). The lead node receives the partial rebuild results over the network and computes complete rebuild data based at least in part on the partial rebuild results.
