摘要： A file system layout apportions an underlying physical volume into one or more virtual volumes (vvols) of a storage system. The underlying physical volume is an aggregate comprising one or more groups of disks, such as RAID groups, of the storage system. The aggregate has its own physical volume block number (pvbn) space and maintains metadata, such as block allocation structures, within that pvbn space. Each vvol has its own virtual volume block number (vvbn) space and maintains metadata, such as block allocation structures, within that vvbn space. Notably, the block allocation structures of a vvol are sized to the vvol, and not to the underlying aggregate, to thereby allow operations that manage data served by the storage system (e.g., snapshot operations) to efficiently work over the vvols.

摘要： An underlying physical volume of a storage system is an aggregate having a plurality of storage devices. The aggregate has its own physical volume block number (pvbn) space. A file system layout apportions the underlying physical volume into a plurality of virtual volumes of the storage system each having a virtual volume identification (vvid). Each virtual volume has its own virtual volume block number (vvbn) space. The block allocation structures of a virtual volume are sized to the virtual volume, and not to the underlying aggregate, to thereby allow operations that manage data served by the storage system (e.g., snapshot operations) to efficiently work over the virtual volumes. Each storage block in a virtual volume is identified by the triplet: pvbn, vvid, and vvbn.

摘要： A method for sharing data blocks in a hierarchical file system in a storage server includes allocating a plurality of data blocks in the file system, and sharing data blocks in the file system, without using a persistent point-in-time image, to avoid duplication of data blocks. A method for identifying data blocks that can be shared includes computing a fingerprint for each of multiple data blocks to be written to a storage facility and storing the fingerprint with information identifying the data block in an entry in a set of metadata. The set of metadata is used to identify data blocks which are duplicates.

摘要： A system and method provides continuous data protection using checkpoints in a write anywhere file system. During a consistency point of a write anywhere file system, freed blocks are identified and are appended to a delete log for retention. A consistency point log is updated with a new entry associated with the consistency point. If the file system needs to retrieve its state at a particular point in time, the stored blocks of the delete log may be recovered.

摘要： A system and method for enabling parallel replay of a backup memory log of client transaction request entries to a network storage appliance file system is provided. The backup memory is typically implemented as a non-volatile random access memory (NVRAM). An initiator establishes a swarm of messages with a plurality of transaction blocks pointing to logged request entries and related states associated therewith. The states represent the various phases of file system recovery and disk storage including a retrieval of disk information (data and meta-data), typically in the form of a LOAD, and a subsequent modify phase. The swarm is transferred to the file system for parallel disk information-retrieval in an interleaved process. Any transactions that cannot be performed due to a required prerequisite action (e.g. a prior file-create) are returned to the initiator for reloading once the prerequisite action has occurred.

摘要： A method and apparatus for operating a data storage system is disclosed. An original active file system holds incoming write transactions. Data is written at a selected time to blocks in a data storage device of the original active file system, the data written to blocks which do not hold old data of the data storage system. Pointers to data of the original active file system are written at the selected time to the data storage device, the pointers written to blocks which do not hold old data of the data storage system, the pointers and a previously saved data of the active file system forming a consistency point of the original active file system at the selected time. A new active file system is started using the consistency point of the original active file system at the selected time.

摘要： A system and method for operating a storage system is provided. A plurality of operating system transaction entries are stored in a log, and a swarm of messages with respect to the plurality of operating system transaction entries is established. The swarm of messages is delivered to an operating system of the storage system. A processor performs a parallel retrieval process for a plurality of messages in the swarm of messages by processing the plurality of messages in an arbitrary order without regard to an underlying order of the messages.
