ABSTRACT:
A dynamically reconfigurable data storage system includes a plurality of storage system controllers, each of which is selectively operable at any given time as one of a channel adapter and a storage device adapter as established by commands received by each of the controllers. At least one semiconductor memory is coupled to the storage system controllers. Additionally, a data storage system director issues commands to each of the storage system controllers for establishing a first quantity of the system controllers as channel adapters, for transmitting and receiving at least data and commands to and from one or more host computers over a plurality of data communication channels. The data storage system director also establishes a second quantity of the storage system controllers as storage device adapters, for cotrolling data transfer to and from a plurality of data storage devices.
