1. A method of cascading failover of blade servers in a data center, the method comprising:

  • transferring by a system management server a data processing workload from a failing blade server to an initial replacement blade server, the data processing workload characterized by data processing resource requirements, the initial replacement blade server having data processing resources that do not match the data processing resource requirements; and

    transferring by the system management server the data processing workload from the initial replacement blade server to a subsequent replacement blade server, the subsequent replacement blade server having data processing resources that better match the data processing resource requirements than do the data processing resources of the initial replacement blade server, including transferring the workload to the subsequent replacement blade server only if the data processing cost of the transfer of the workload to the subsequent replacement blade is less than the value of a transfer cost threshold.
