Abstract
A method and computer program product for receiving a data read request on a first array for requested data stored on a multi-array storage network that includes the first array and at least a second array. The data read request is processed to determine if the requested data is resident on the first array. If the requested data is resident on the first array, the requested data is obtained from a storage device included within the first array. If the requested data is not resident on the first array, the requested data is obtained from a storage device included within the at least a second array via an out-of-band cache control process.
