Abstract: A system is provided for storing data for a plurality of host computers (20) on a plurality of storage arrays so that data on each storage array can be accessed by any host computer. A plurality of adapter cards (22) are used. Each adapter has controller functions for a designated storage array. There is an adapter communication interface (23) (interconnect) between all of the adapters in the system. There is also a host application interface between an application program running in the host computer and an adapter. When a data request is made by an application program to a first adapter through a host application interface for data that is stored in a storage array not primarily controlled by the first adapter, the data request is communicated through the adapter communication interface to the adapter primarily controlling the storage array in which the requested data is stored.
