    摘要： Data storage devices of an enterprise system are tested to determine whether the enterprise system is optimally configured. Each data storage device is tested to determine whether it can satisfy a performance requirement for an assigned group of n workloads. A group of n inequalities are generated, and only up to n of the inequalities may be evaluated to determine whether the device satisfies the performance requirement for the assigned group of workloads. The inequalities are based on a phased, correlated model of I/O activity.

    摘要： The value of a p-quantile of a workload distribution is computed to determine whether a data storage system satisfies a quality-of-service guarantee desired by a client. The quality-of-service guarantee may be a predetermined percentage of a workload being serviced by a device within a predetermined response time. A p-quantile value is set to be equal of the predetermined percentage of the quality-of-service guarantee, and a bound is set to be equal to the predetermined response time. A distribution for the workload arriving at the device during an interval of time equal to the bound is then estimated. It is then determined whether a p-quantile of the workload distribution is less than the bound. In cases where the p-quantile of the workload distribution is computed directly, then the p-quantile of the workload distribution is directly compared to the bound. In cases where the p-quantile of the workload distribution is not computed directly, then the p-quantile of the workload distribution is estimated, with the estimated value the compared to the bound.

    摘要： An embodiment of a method of designing a storage system begins with a step of assigning decision variables to a range of candidate storage systems. Each of the decision variables identifies a single candidate storage system. The method concludes with a step of employing the decision variables in a mathematical program to determine which of the candidate storage systems meets availability and reliability criteria and incurs a near minimal projected cost.

    摘要： An embodiment of a method of cooperative caching for a distributed storage system begins with a step of requesting data from storage devices which hold the data. The method continues with a step of receiving any cached blocks and expected response times for providing non-cached blocks from the storage devices. The method concludes with a step of requesting a sufficient number of the non-cached blocks from one or more particular storage devices which provides an expectation of optimal performance.
