The blades or individual servers installed in a server blade chassis provide for high density server function. The fact that the individual blades are inexpensive and can be easily hot plugged provides for some level of redundancy and fault tolerance. If a blade malfunctions, the processing power can be easily replaced by inserting another blade. However, data stored on the malfunctioning blade's hard disks are lost. In addition, the blade architecture doesn't allow for storage expansion or fault tolerance, for example, it is not possible to easily add a RAID subsystem to a blade chassis. This invention provides for the recovery of lost data on a blade if it malfunctions.
