ABSTRACT:
A cluster network that includes multiple server nodes is disclosed. Each of the multiple nodes of the cluster network is coupled to first and second expander devices. The cluster network includes a number of storage enclosures, each of which includes dual interface and a number of dual port storage devices. Each of the dual port storage devices are coupled to each interface of the storage enclosure. Each interface is coupled to one of the expander devices. If one of the expander devices fails, the server nodes of the cluster network can access each other peer server node and each storage drive of the cluster network.
