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