ABSTRACT:
In one embodiment of the present invention, an adapter device is provided that may be used in a data storage system to permit data communication among host computer nodes external to the system and data storage system processors. The adapter device of this embodiment includes two or more network nodes configured to provide at least one network. The network may be used to interconnect the host computer nodes and the processors so as to permit the data communication among the host computer nodes and the processors. At least one of the network nodes is configurable so as to change the topology of the network. When the network's topology is changed in this manner, the nature of the data communication permitted by the network among at least certain of the processors and the host computer nodes is also changed.
