A plurality of servers arranged in a cluster, such as a plurality of blade servers, may communicate with a network over a first communication path. The servers may also communicate with each other over another communication path such as an out-of-band channel. Using the out-of-band channel, a server that is having a communication or a software failure may communication with other blade servers using the out-of-band channel. The other blade servers may act as a proxy for the server with a problem, enabling the proxy to communicate on behalf of the server having a communication problem. As a result, useful computational work may be obtained in many cases from servers that would otherwise be taken off-line.
