    Abstract: A technique for eliminating duplicate data is provided. Upon receipt of a new data set, one or more anchor points are identified within the data set. A bit-by-bit data comparison is then performed of the region surrounding the anchor point in the received data set with the region surrounding an anchor point stored within a pattern database to identify forward/backward delta values. The duplicate data identified by the anchor point, forward and backward delta values is then replaced in the received data set with a storage indicator.

    Abstract: A method, apparatus, and system for providing role-based access control (RBAC) for storage management are described herein. Resource- identifying information is stored in a role-based access database for a network storage system, in association with role-identifying information for each of a plurality of roles and operation-identifying information. The operation- identifying information indicates one or more authorized operations for each of the plurality of roles and the resource-identifying information identifies specific resources maintained by the network storage system. The role-identifying information, data indicating one or more authorized operations for at least one of the roles, and resource-specific identifying information in the role-based access database are used to determine whether to allow or deny a request from a network storage client to access a resource maintained by the network storage system.

    Abstract translation: 这里描述了用于为存储管理提供基于角色的访问控制（RBAC）的方法，装置和系统。 资源识别信息与用于多个角色和操作识别信息中的每一个的角色识别信息相关联地存储在网络存储系统的基于角色的访问数据库中。 操作识别信息指示用于多个角色中的每一个的一个或多个授权操作，并且资源识别信息识别由网络存储系统维护的特定资源。 角色识别信息，指示至少一个角色的一个或多个授权操作的数据以及基于角色的访问数据库中的资源特定识别信息被用于确定是允许还是拒绝来自网络存储客户端 访问由网络存储系统维护的资源。

    Abstract: Embodiments of the present invention provide a method, system, and computer program product for optimizing I/O operations performed by a storage server operating on behalf of multiple clients to access data on a plurality of storage devices (disks). Embodiments of the present invention eliminate the need for selected read operations to write new data to physical data blocks by zeroing the physical data blocks to which new data will be written. Additionally, the need for reading old parity to compute new parity is eliminated. Instead, new parity is computed from the data to be written without the need of old parity or the storage server sends a command to a disk that stores parity. A module implemented at the disk that stores parity executes the command without reading, by the storage server, old parity. Eliminating the need for reading old data and for reading old parity eliminates some rotation latency and improves overall system's performance.

    Abstract: A system and method for managing data deduplication of a storage system utilizing persistent consistency point images (PCPIs). Once a target PCPI of a data transfer is generated, a backup management module of the storage system alerts a data deduplication module to begin deduplication of the data contained within the target PCPI. Once the deduplication procedure has been completed, the active file system of the storage system has been deduplicated, however, the target PCPI remains un-deduplicated. In response, the backup management module generates and exports a revised target PCPI. The previous target PCPI may then be deleted, thereby transitioning the exported PCPI's image of the state of the file system to a deduplicated state.

    Abstract: A storage server creates a first mirror of a primary volume of data on a first storage set that includes at least one disk and creates a second mirror of the primary volume, on a second storage set that also includes at least one disk. The server then quiesces the second storage set. A user then decouples the second storage set from the server and transports the second storage set off-site. The storage server then saves one or more incremental backups of the primary volume on the first storage set according to a specified backup schedule. According to a specified rotation schedule, a user subsequently recouples the second storage set to the server. The server detects the recoupling and, in response, automatically resynchronizes the second mirror with the primary volume, and swaps the active-inactive statuses of the first and second mirrors. The process repeats as needed.
