ABSTRACT:
A warm standby appliance is described herein. The warm standby appliance is coupled to a storage server which is coupled to one or more servers. When a server fails, the storage server transfers a backed up image to the warm standby appliance, so that the warm standby appliance is able to replicate the failed server. While the failed server is inaccessible, the warm standby appliance is able to mimic the functionality of the failed server. When a new server or repaired server is available, the warm standby appliance is no longer needed. To incorporate the new server into the system quickly and easily, the server image of the warm standby appliance is sent to the new server. After transferring the image, the warm standby appliance is cleaned and returns back to a dormant state, waiting to be utilized again.
