    • A computer implemented method for generating a storage policy for a storage system based on simulation results associated with a state of the storage system is provided. The method comprises receiving a target function applicable to a storage system, wherein the target function represents a measure of values associated with storage parameters related to productivity and loss tolerance of the storage system; wherein the simulation results for a state of the storage system are calculated based on a least one of (a) the storage system simulated response to a set of simulated file-related storage operation requests generated based on one or more simulation rules, (b) the state of the storage system before responding to the set of simulated file-related storage operation requests, (c) the storage system target function; and (d) rules for simulating file-related storage operation requests.
    • 提供了一种基于与存储系统的状态相关联的模拟结果来生成用于存储系统的存储策略的计算机实现的方法。 该方法包括接收适用于存储系统的目标函数,其中目标函数表示与存储系统的生产率和损耗容限相关的存储参数相关联的值的量度; 其特征在于,基于以下至少一个来计算所述存储系统的状态的模拟结果:(a)基于一个或多个模拟规则生成的与一组模拟文件相关的存储操作请求的存储系统模拟响应,(b) 存储系统的状态在响应模拟文件相关存储操作请求集合之前,(c)存储系统目标函数; 和(d)用于模拟与文件相关的存储操作请求的规则。

    • In one embodiment, a method for remote mirroring includes providing a control entity coupled to a primary site and a secondary site, receiving first memory space information indicative of a location of a first memory space, establishing a remote mirroring relationship between the primary site and the secondary site, copying data from the primary site to the secondary site, and writing status information to the first memory space for storing status information representative of a relationship between data stored in the primary site and destined to be copied to the secondary site and data copied from the primary site to the secondary site.
    • 在一个实施例中,用于远程镜像的方法包括提供耦合到主站点和辅站点的控制实体,接收指示第一存储器空间的位置的第一存储器空间信息,在主站点和第二站点之间建立远程镜像关系 次要站点,将数据从主站点复制到辅助站点,以及将状态信息写入到第一存储器空间,用于存储表示存储在主站点中并且将要复制到辅助站点的数据与复制的数据之间的关系的状态信息 从主站点到辅助站点。
