    摘要： Throughput of a high-volume throughput-centric computer system is controlled by dynamically adjusting a concurrency level of a plurality of events being processed in a computer system to meet a predetermined target for utilization of one or more resources of a computer system. The predetermined target is less than 100% utilization of said one or more resources. The adjusted concurrency level is validated using one or more queuing models to check that said predetermined target is being met. Parameters are configured for adjusting the concurrency level. The parameters are configured so that said one or more resources are shared with one or more external programs. A statistical algorithm is established that minimizes total number of samples collected. The samples may be used to measure performance used to further dynamically adjust the concurrency level. A dynamic thread sleeping method is designed to handle systems that need only a very small number of threads to saturate bottleneck resources and hence are sensitive to concurrency level changes.

    摘要： a virtual storage module operable to run in a virtual machine monitor may include a wait-queue operable to store incoming block-level data requests from one or more virtual machines. In-memory metadata may store information associated with data stored in local persistent storage that is local to a host computer hosting the virtual machines. The data stored in local persistent storage replicates a subset of data in one or more virtual disks provided to the virtual machines. The virtual disks are mapped to remote storage accessible via a network connecting the virtual machines and the remote storage. A cache handling logic may be operable to handle the block-level data requests by obtaining the information in the in-memory metadata and making I/O re-quests to the local persistent storage or the remote storage or combination of the local persistent storage and the remote storage to service the block-level data requests.

    摘要： A method and system for managing a service level of a service provided by a service provider to a customer under a service level agreement. The actual measurement data is adjudicated to correct the measurement data in accordance with at least one adjudication element that provides information relating to how to correct the measurement data. The adjudicated measurement data is transformed into operational data by being reorganized into one or more groups of data. The operational data is evaluated by applying a formula to the operational data, resulting in the operational data being configured for being subsequently qualified. The operational data is qualified by comparing the evaluated operational data with specified service level targets for at least one service level period and identifying operational data points meeting and/or not meeting the specified service level targets.
