    • Methods and apparatus are disclosed for managing access to data in a data storage system. For example, an apparatus comprises at least one processing platform associated with a distributed virtual infrastructure. The processing platform comprises at least one processing device having a processor coupled to a memory. The processing platform is operative to instantiate a meta data management process that is configured to provide at least one client process with information to allow the client process to perform one or more operations in accordance with one or more data storage devices through a storage area network. The information provided to the client process may comprise one or more data block descriptors. Each of the one or more data block descriptors may comprise path information for at least one of the data storage devices and an offset address in the at least one data storage device. The one or more data block descriptors may correspond to one or more data blocks of a given data file that is stored or storable across the one or more data storage devices.
    • 公开了用于管理对数据存储系统中的数据的访问的方法和装置。 例如,设备包括与分布式虚拟基础设施相关联的至少一个处理平台。 处理平台包括至少一个具有耦合到存储器的处理器的处理设备。 处理平台用于实例化元数据管理过程,其被配置为向至少一个客户端进程提供信息以允许客户端进程根据一个或多个数据存储设备通过存储区域网络执行一个或多个操作。 提供给客户端进程的信息可以包括一个或多个数据块描述符。 所述一个或多个数据块描述符中的每一个可以包括至少一个数据存储设备的路径信息和至少一个数据存储设备中的偏移地址。 一个或多个数据块描述符可以对应于一个或多个数据文件的一个或多个数据块,该数据块可被存储或存储在一个或多个数据存储设备上。
