    摘要： Systems and methods for path selection for application commands are described. To this end, information associated with at least one application command that were processed at least one port of a target device is received. For a subsequent application command, a set of ports of the target device is determined. In one implementation, the set of ports is determined based on information associated with the subsequent application command. Once the set of ports is determined, the subsequent application command is directed to a port selected from the set of ports.

    摘要： Embodiments include methods, apparatus, and systems for prefetching data in distributed storage systems. One method of software execution includes using input/output (I/O) requests from multiple separate networked storage nodes in a distributed storage system to prefetch data for one of the multiple separate networked storage nodes.

    摘要： A method predicts performance of a system that includes a plurality of interconnected components defining at least one data flow path. The method references a workload specification for the system. The method models the system using one or more component models. Each component model represents selected one or more of the components. Each component model is arranged in like relationship to the data flow path as the selected one or more of the components represented by the component model. Each component model is (a) a constraint upon the workload specification input to that component model or (b) a transformer of the workload specification input to that component model so as to result in one or more output workload specifications that are input workload specifications to subsequent component models along the data flow path or (c) both a constraint and a transformer. At least one of the component models is a constraint. At least some of the component models along the data flow path operate on the workload specification. In one preferred form, operating on the workload specification involves arranging the component models in a hierarchy corresponding to the data flow path; using the specified workload specification as input to the topmost component model in the hierarchy; and applying one or more of the component models to its input workload specification, starting with the topmost component model and then component models at progressively lower levels in the hierarchy. Output workload specification at one level is input workload specification at the next lower level. If the component model comprises a constraint, the method evaluates whether the input workload specification satisfies or violates the constraint. If the component model comprises a workload specification transform, the method modifies the input workload specification so as to produce one or more output workload specifications.

    摘要： A system includes disk storage to provide differentiated storage QoS for a plurality of IO classes. Each IO class has a plurality of applications to it. A QoS controller collects IO statistics for each application and each class. The QoS controller adaptively determines an IO class assignment for each application based at least in part on the collected IO statistics.
