摘要： A technique of managing data placement involves constructing an active extent list which identifies active extents stored in a storage pool based on a history of extent activity. The technique further involves based on the active extent list, generating preferred extent-tier pairings for extents of a particular LUN slice that are initially stored on a first tier of the pool, the preferred extent-tier pairings matching (i) a first extent of that LUN slice to the first tier and (ii) a second extent of that LUN slice to a second tier of the pool. The technique further involves, based on the preferred extent-tier pairings, maintaining the first extent on the first tier and relocating the second extent from the first tier to the second tier to distribute the first and second extents of that LUN slice across multiple tiers of the pool in accordance with the extent activity history.

摘要： This invention is a system and a method for operating a storage server that provides read or write access to a data in a data network using a new architecture. The method of processing I/Os in response to a request by a client of the storage server executes one or more services communicated by a policy engine. The I/Os received from the application are tagged and catalogued to create co-related I/O patterns. The policy engine is then updated with the results of processing the I/Os after executing services on those I/Os.

摘要： One embodiment of the invention relates to the transfer of content between a host computer that issues OAS access requests and a block I/O storage system. Specifically, a host computer may issue an access request for a content unit that identifies the content unit is an object identifier. The request may be received by a second server, which may determine the block address(es) on the block I/O storage system at which the content unit is stored. A request may then be sent to the block I/O storage system to retrieve the content stored at the requested block address(es) and the block I/O storage system may return the content.

摘要： Aspects of the invention relate to creating a snapshot of a file system on an OAS system. A snapshot of a file system is an image of a file system at a particular point in time. A snapshot of a file system may be used to restore the file system to its state at the time of creation of the snapshot in, for example, situations where the file system has become corrupted.

摘要： A snapshot copy facility stores snapshot copies of a production, file system. The snapshot copy facility receives a request for the difference between a specified older snapshot,copy and a specified younger snapshot copy, and responds by returning the difference between the older snapshot copy and the younger snapshot copy. In a preferred implementation, the snapshot copy facility has an index for each snapshot copy for indicating blocks of data in the production file system that have changed between the snapshot copy and a next snapshot copy of the production file system. The indices are scanned for a sequence of the snapshot copies to determine the blocks that have changed, and the snapshot copy facility returns the block numbers and data in the younger snapshot copy for the blocks that have changed.

摘要： For disaster recovery of a file server at an active site, the files that define the user environment of the file server are replicated to a virtual server at a disaster recovery site. To switch over user access from the active site to the disaster recovery site, the disaster recovery system determines whether there are sufficient network interfaces and file system mounts at the disaster recovery site. If so, the required resources are reserved, and user access is switched over. If not, an operator is given a list of missing resources or discrepancies, and a choice of termination or forced failover. Interruptions during the failover can be avoided by maintaining a copy of user mappings and a copy of session information at the disaster recovery site, and keeping alive client-server connections and re-directing client requests from the active site to the disaster recovery site.

摘要： One embodiment of the invention is directed to the containerization of content units that are accessed using an identifier. Applicants have appreciated that file systems sometimes impose limits on the number of files that may be stored therein that are too restrictive. Thus, in one embodiment, multiple content units may be stored in a single file, called a container file, in a file system. Each content unit may have an identifier associated with it. When an accessing entity requests access to a previously-stored content unit and provides the identifier for the content unit, the identifier may be used to locate the container file in which the content unit is stored.

摘要： One embodiment of the invention is directed to providing a single instance storage capability in a content addressable computer system that stores content units in a time-based directory structure. Another embodiment is directed to managing access to content units that do not include a timestamp in their content addresses, in a time-based directory structure. A further embodiment is directed to accessing replicated content units stored on a computer, based on a time of replication. A further embodiment is directed to employing a bitmap in a time-based directory structure which may be used to indicate whether any content units stored during a specified time range are stored in the directory structure.

摘要： A file server maintains a series of read-only snapshot copies of a production file system. A read-write snapshot copy is created based on a selected read-only snapshot copy by maintaining a set of save volume blocks of new data of the read-write snapshot copy. A block of new data is written to the read-write snapshot copy by allocating a save volume block and writing to the save volume block. A specified block is read from the read-write snapshot copy by checking whether there is a respective save volume block allocated to the specified block, and if so, reading from the respective save volume block, and if not, reading from the read-only snapshot copy upon which the read-write snapshot copy is based. The read-write snapshot copy can be refreshed with a specified read-only snapshot copy. The production file can be restored with a specified read-write snapshot copy.
