    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.

    Abstract translation: 存储服务器在包括至少一个磁盘的第一存储集上创建主卷数据的第一镜像，并在还包括至少一个盘的第二存储集上创建主卷的第二镜像。 服务器然后停止第二个存储集。 然后，用户将第二存储集与服务器分离，并将第二存储集传送到异地。 然后，存储服务器根据指定的备份计划将第一个存储集上的主卷的一个或多个增量备份保存。 根据指定的旋转计划，用户随后将第二存储集合重新连接到服务器。 服务器检测到重新连接，并且作为响应，自动将第二个镜像与主卷重新同步，并交换第一个和第二个镜像的活动不活动状态。 该过程根据需要重复。

    Abstract: The intelligent distributed file system enables the storing of file data among a plurality of smart storage units which are accessed as a single file system. The intelligent distributed file system utilizes a metadata data structure to track and manage detailed information about each file, including, for example, the device and block locations of the file's data blocks, to permit different levels of replication and/or redundancy within a single file system, to facilitate the change of redundancy parameters, to provide high-level protection for metadata, to replicate and move data in real-time, and to permit the creation of virtual hot spares among the smart storage units without the need to idle any single smart storage unit in the intelligent distributed file system.

    Abstract: A data backup system and a method for sychronizing a replication of permanent data between primary and secondary disk subsystems and a replication of temporary data between primary and secondary computer servers in the event of an operational error are provided. The method includes detecting an operational error. The method further includes stopping replication of permanent data from the primary disk subsystem to the secondary disk subsystem at a first predetermined time, in response to the detection of the operational error. The method further includes stopping any further replication of temporary data from the primary computer server to the secondary computer server at the first predetermined time, in response to the detection of the operational error.

    Abstract: Disclosed is a method and apparatus for reading mirrored data. In one embodiment, a node receives a read request for data, identical copies of which are maintained on a primary storage device and any number of corresponding mirrors. A read generator coupled to the node generates a number of read operations for smaller portions of the data. Preferably, the read generator then transmits the read operations in parallel to at least two storage devices on which identical copies of the data are maintained (e.g., a primary storage device and a corresponding mirror, two mirrors of a primary storage device, etc.). The read operations may then be processed in parallel by the storage devices to which the read operations were transmitted.

    Abstract: A storage virtualization environment is provided that includes a network switch system for initializing a virtual volume in a system including a host system, and storage devices. The network switch system includes storage processors including first and second tier storage processors and a Virtualization Coherency Manager (VCM) for receiving storage connectivity identifying which storage processors are connected to selected ones of the storage devices. Further, the network switch system includes a master storage processor for creating a logical tree based on the storage connectivity information, the logical tree reflecting a virtual volume of data distributed across the storage devices and includes (i) first tier objects representing partitions of the virtual volume data and (ii) second tier objects representing a logical configuration of the virtual volume. In one embodiment, the VCM assigns the first tier objects to selective ones of the first tier storage processors and assigns the second tier objects to selective ones of the second tier storage processors based on the logical tree. Further, each of the selective first and second tier storage processors initialize a local portion of the virtual volume to allow the host system to access the virtual volume through the network switch system.

    Abstract: An apparatus and method are provided in a computer network to decouple client computers from file servers, by placing a transparent network node, also termed a file switch or file switch computer, between the client computers and the file servers. Usage of such a file switch allows reduced latency in file transfers, as well as scalable mirroring, striping, spillover, and other features. The file switch preferably includes at least one processing unit for executing computer programs, at least one port for exchanging information with the file servers and client computers, and a file aggregation module. The file aggregation module includes computer programs for determining a set of file servers from the group of file servers for storing a specified user file, creating a metadata file storing information identifying the set of file servers for storing the user file; and updating directory structures on the set of file servers to indicate storage of the user file.
