    • Described are techniques for provisioning storage of a data storage system for use by an application. One or more application provision requirements associated with a provisioning request to provision storage for use by the application are received. The one or more application provision requirements are translated, in accordance with application best practices for the application included in a policy, to one or more generic storage resource requirements. The one or more generic storage resource requirements are translated, in accordance with data storage system best practices included in said policy, to one or more physical data storage requirements. The physical data storage requirements include identification of one or more physical storage devices in said data storage system used in allocating storage to service said provisioning request. Storage is allocated for use by said application in accordance with said physical data storage requirements.
    • 描述了用于供应存储应用程序使用的数据存储系统的技术。 接收与供应请求相关联的一个或多个应用提供要求,以供应用于由应用使用的存储。 一个或多个应用程序提供要求根据应用程序中包含在策略中的应用最佳实践转换为一个或多个通用存储资源要求。 根据包括在所述策略中的数据存储系统最佳实践,将一个或多个通用存储资源需求转换为一个或多个物理数据存储要求。 物理数据存储要求包括识别用于分配存储以服务所述供应请求的所述数据存储系统中的一个或多个物理存储设备。 所述应用程序根据所述物理数据存储要求分配存储。

    • A system, method and program product for processing a stream of data events using scaled exponential smoothing for maintaining a histogram. A system is provided having: a set of histogram data that maintains a running value for each of a plurality of buckets; a bucket identification system for identifying a bucket b into which a new data event value belongs; an exponential smoothing system that applies a decay factor to the set of histogram data utilizing a first algorithm for the running value associated with bucket b, and a second algorithm for each remaining running value; and an analysis system for analyzing data event values in view of the histogram data.
    • 一种用于使用缩放指数平滑处理数据事件流以维持直方图的系统,方法和程序产品。 提供了一种系统,其具有:维持多个桶中的每个桶的运行值的一组直方图数据; 用于识别新数据事件值所属的桶b的桶识别系统; 指数平滑系统,使用用于与桶b相关联的运行值的第一算法将衰减因子应用于直方图数据集,以及针对每个剩余运行值的第二算法; 以及用于根据直方图数据分析数据事件值的分析系统。

    • One embodiment is a method and apparatus for modifying retention periods in a storage system, in which previously defined retention periods for units of data may be reduced. In another embodiment, the retention period of a unit of data may be modified in response to the occurrence of an event by renewing previously defined retention periods until the occurrence of the event is detected. If the occurrence of the event is detected, a retention period associated with that event may be established for the unit of data. In yet another embodiment, retention classes are used to define retention periods for units of data so that the retention period of a unit of data may be modified without modifying the unit of data itself. In a further embodiment, a request to the storage system to reduce a retention period includes authentication information that the storage system may use to verify the request.
    • 一个实施例是用于修改存储系统中的保留周期的方法和装置,其中可以减少用于数据单元的先前定义的保留期。 在另一个实施例中,可以通过更新先前定义的保留时段来响应于事件的发生来修改数据单元的保留期,直到检测到事件的发生。 如果检测到事件的发生,则可以针对数据单元建立与该事件相关联的保留期。 在另一个实施例中,保留类别用于定义数据单元的保留期,使得可以在不修改数据单元本身的情况下修改数据单元的保留期。 在另一实施例中,对存储系统的减少保留期限的请求包括存储系统可用于验证请求的认证信息。
