Abstract
A system remotely boots a plurality of server blades in a blade center to update each blade. A temporary network is created to provide an out-of-band communication channel between a management module and the plurality of server blades. The management module receives and saves the original boot sequence for each server blade and alters each boot sequence such that each server blade begins with a network boot. After receiving an initial transmission over the network containing server blade boot instructions and storing the boot instructions in a temporary boot server, subsequent server blade boot requests from the network are intercepted and the stored boot instructions are re-routed from the temporary boot server to each of the remaining blades in the blade server thus removing the need for repeated boot packet transmission over the network.
