    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： 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： A method of and apparatus for determining whether a multi-component target system meets a given multi-part performability requirement is provided. A description of the target system, failure probabilities for components of the target system and a multi-part performability requirement for the target system are obtained. The multi-part performability requirement indicates desired performance levels and corresponding fractions of time. One or more failure-scenarios are successively computed that represent one or more states of the target system having zero or more components failed and a corresponding probability of occurrence of the one or more of the states of the target system. Performance of the target system is modeled under the failure scenarios using a performance predictor module for generating a multi-part performability function. The multi-part performability function is compared with said multi-part performability requirement to determine whether the target system meets the multi-part performability requirement.

    摘要： A communication system utilizes at least one digital subscriber line access multiplexer (DSLAM) at an intermediate point between a network facility and one or more customer premises. Initially, as few as one DSLAM, may be implemented at the intermediate point, but the system can be expanded to include any number of DSLAMs at the intermediate point. Any of the DSLAMs at the intermediate point can be selectively upgraded at any time to a vectoring solution as may be desired. The use of such DSLAMs provides the network service provider with flexibility in implementing and maintaining the network.

    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： Provided are, inter alia, systems, methods and techniques for controlling workflow by identifying an individual job that is part of an overall deliverables package that covers multiple jobs. An aggregate utility function is obtained, specifying utility based on an aggregate metric across the overall deliverables package, and a current operating point is determined on the aggregate utility function. An effective utility is calculated for the individual job based on the aggregate utility function and the current operating point, and the execution of work is controlled based on the effective utility for the individual job.
