Abstract
A storage controller is operable concurrently as an independent storage server and as at least a portion of a node of a storage server cluster. A network storage system comprises multiple storage controllers and multiple independent storage servers, each storage server implemented in a separate storage controller, each of the storage server configured to present to users a separate system image of stored data. The storage servers are independently operable and manageable. The system further includes a storage server cluster that includes cooperating storage server nodes, distributed among the storage controllers. The storage server cluster presents to users a single system image of data stored in the server cluster independently of the node or nodes in which said data resides. The storage server cluster is operable independently of the independent storage servers and is operable concurrently with operation of at least one of the independent storage servers.
