    摘要: A technique is disclosed for restoring data of sparse volumes, where one or more block pointers within the file system structure are marked as ABSENT, and fetching the appropriate data from an alternate location on demand. Client data access requests to the local storage system initiate a restoration of the data from a backing store as required. A demand generator can also be used to restore the data as a background process by walking through the sparse volume and restoring the data of absent blocks. A pump module is also disclosed to regulate the access of the demand generator. Once all the data has been restored, the volume contains all data locally, and is no longer a sparse volume.

    摘要: A system and method are provided to manage configuration of multiple file server appliances. The method comprises receiving a read request and, responsive to the receiving of the read request, utilizing a readahead engine to issue a readahead request. A portion of the readahead request that can be read from a local storage is delivered to the local storage system. A portion of the readahead request that can be read from a remote storage is delivered to the remote storage system.
