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.

The file system layout extends the file system layout of a conventional write anywhere file layout system implementation, yet maintains performance properties of the conventional implementation.

摘要： A technique translates a hybrid virtual volume (vvol) having a file system that contains intermingled virtual and physical volume block numbers (vbns) into a “pure” stream of virtual vbns (vvbns). The stream of vvbns is illustratively embodied as an output file system data stream of a vvol image that is transferred by a source storage system (“source”) to a destination storage system (“destination”) in accordance with image transfer operations, such as volume copying and synchronous or asynchronous mirroring, provided by a volume replication facility. The blocks that are sent as part of the image transfer are selected from a container file of the hybrid vvol on the source. In particular, the invention is directed to a technique for translating physical vbns (pvbns) of a source aggregate on the source to pure vvbns of the output file system data stream that can be used on a destination aggregate of the destination, where embedded pvbns in the source hybrid vvol image are not valid.

摘要： A technique converts a stream of virtual volume block numbers (vvbns) into a hybrid virtual volume (vvol) file system containing both physical volume block numbers (pvbns) and vvbns. The stream of vvbns is illustratively embodied as a file system data stream of a vvol that is transferred by a source to a destination in accordance with image transfer operations, such as volume copying and synchronous or asynchronous mirroring. Transfer of the vvol involves converting a file system on the source vvol into the file system data stream (i.e., a “pure” vvol stream), where all blocks of the vvol are represented by vvbns. The file system data stream is then transferred to the destination, where the vvbns of the pure vvol stream blocks are converted to pvbns of a hybrid stream.

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.
