    Abstract: PROBLEM TO BE SOLVED: To provide a method, a system, and a program for using multiple data structures to manage data in cache. SOLUTION: A plurality of data structures each have entries identifying data from a first computer readable medium added to a second computer readable medium. A request is received for data in the first computer readable medium. A determination is made as to whether there is an entry for the requested data in one of the data structures. The requested data is retrieved from the first computer readable medium to store in the second computer readable medium in response to determining that there is no entry for the requested data in one of the data structures. One of the data structures is selected in response to determining that there is no entry for the requested data in one of the data structures and an entry for the retrieved data is added to the selected data structure.

    Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method to reconfigure a storage array disposed in a data storage system.
    SOLUTION: Each of a plurality of data storage devices is assigned to one of a plurality of data storage arrays, or is assigned as a spare device. The method detects an unassigned data storage device, and determines if any of the plurality of data storage arrays comprises a degraded data storage array. If the method determines that any of the plurality of data storage arrays comprises a degraded data storage array, then the method determines if the unassigned data storage device can be used to restore the degraded data storage array to optimal reliability, optimal performance, and optimal efficiency. If the method determines that the unassigned data storage device can be used to restore the degraded array to an array comprising optimal reliability, optimal performance, and optimal efficiency, then the method reconfigures the degraded data storage array to comprise the unassigned data storage device.

    Abstract: A storage controller that includes a cache receives a command from a host, wherein a set of criteria corresponding to read and write response times for executing the command have to be satisfied. The storage controller determines ranks of a first type and ranks of a second type corresponding to a plurality of volumes coupled to the storage controller, wherein the command is to be executed with respect to the ranks of the first type. Destage rate corresponding to the ranks of the first type are adjusted to be less than a default destage rate corresponding to the ranks of the second type, wherein the set of criteria corresponding to the read and write response times for executing the command are satisfied.
