Cascading failover of blade servers in a data center
First Claim
1. A method comprising:
- transferring 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 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;
wherein the data processing workload is executed on a virtual machine on the failing blade server; and
the data processing resource requirements are implemented as virtual machine metadata describing the data processing resource requirements of the virtual machine.

Abstract
Cascading failover of blade servers in a data center that includes transferring by a system management server a data processing workload from a failing blade server to an initial replacement blade server, with the data processing workload characterized by data processing resource requirements and the initial replacement blade server having data processing resources that do not match the data processing resource requirements; and transferring the data processing workload from the initial replacement blade server to a subsequent replacement blade server, where the subsequent replacement blade server has 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.

7. A system management server comprising a computer processor and a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that when executed by the processor cause the system management server to carry out the steps of:
-
transferring 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 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; wherein the data processing workload is executed on a virtual machine on the failing blade server; and the data processing resource requirements are implemented as virtual machine metadata describing the data processing resource requirements of the virtual machine. - View Dependent Claims (8, 9, 10, 11, 12)

13. A computer program product including a non-transitory computer readable storage recordable medium, the computer program product comprising computer program instructions when executed by a computer processor cause a system management server of the data center to carry out the steps of:
-
transferring 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 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; the data processing workload is executed on a virtual machine on the failing blade server; and the data processing resource requirements are implemented as virtual machine metadata describing the data processing resource requirements of the virtual machine. - View Dependent Claims (14, 15, 16, 17, 18)
