Abstract
A method and apparatus for partitioning a computer cluster through coordination point devices that provide enhanced split brain arbitration during I/O fencing. In one embodiment, a method for using coordination point devices to support Input/Output fencing in a computer cluster comprises processing at least one arbitration request from at least one client computer upon an occurrence of a split brain within a computer cluster, wherein each arbitration request indicates at least one established connection between at least one coordination point device and each client computer of the at least one client computer and each client sub-cluster membership, wherein the at least one coordination point device form a coordination point cluster membership and selecting a client computer of the at least one client computer to continue to be a portion of the computer cluster based on the arbitration request.
