    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.

    摘要： A system and method for allocating resources on a shared storage system are disclosed. The system 10 can include a shared storage device 12 and a plurality of port schedulers 14 associated with a plurality of I/O ports 16 that are in communication with the shared storage device 12. Each port scheduler 14 is configured to enforce a concurrency level and a proportional share of storage resources of the shared storage device 12 for each application 18 utilizing the associated port. The system 10 can also include a resource controller 17 that is configured to both monitor performance characteristics of the applications 18 utilizing at least one of the I/O ports 16, and to adjust the concurrency level and the proportional share of storage resources parameters of the port schedulers 14 for at least a portion of the applications 18 in order to vary allocation of the resources of the shared storage device 12.

    摘要： Systems, methods, and computer-readable and executable instructions are provided for selecting executing requests to preempt. Selecting executing requests to preempt can include determining whether an application is in an overload condition. Selecting executing requests can also include in response to determining the application is in an overload condition, identifying each request that is being executed by the application. Selecting executing requests can also include determining a value for each request that is executing. Furthermore, selecting executing requests can also include selecting executing requests to preempt based on the values for the requests.

    摘要： A system comprises a processor and an alert module coupled to the processor. The processor the processor monitors performance data; determines a subset of the performance data, the subset correlated with a measure of underperformance; determines a trend of the subset, the trend correlated with the measure; and identifies an occurrence of the trend. The alert module outputs an alert based on the identification.
