    摘要： A method for providing data indicative of the performance of a competing algorithm and an incumbent algorithm includes evaluating an incumbent-algorithm score indicative of a performance of an incumbent algorithm. The performance of a competing algorithm executing in place of the incumbent algorithm is then simulated. On the basis of the simulation, a competing-algorithm score predictive of a performance of the competing algorithm is evaluated. These scores are then provided to an output device.

    摘要： Load balancing of activities on physical disk storage devices is accomplished by monitoring reading and writing operations to logical volumes on the physical disk storage devices. A list of exchangeable pairs of logical volumes is developed based on size and function. Statistics accumulated over an interval are then used to obtain access activity values for each logical volume and each physical disk drive. A statistical analysis selects one logical volume pair. After testing to determine any adverse effect of making that change, the exchange is made to more evenly distribute the loading on individual physical disk storage devices.

    摘要： A method and apparatus for reconfiguring a file or logical volume stored on a magnetic disk storage system for optimal performance. The magnetic disk storage system contains a cache volume constituted as free storage. When appropriate, a file can be copied from its normal storage location to the cache volume with a different format to optimize the file for subsequent operations. After such operations are complete, the file can be transferred from the cache volume back to the normal storage location in the original format.
