摘要： A method for reading data from a data storage system is provided. The method comprises requesting a virtual data volume to access data from one or more data blocks in the data storage system; requesting a virtual protection information volume to access protection information associated with the data blocks; validating the data using the protection information; and providing the data to the host interface, in response to successful validation of the data. A method for writing data to a data storage system is also provided. The method comprises receiving data to be written to one or more data blocks in the data storage system, wherein the data is stored in a cache; generating protection information to be stored on a virtual protection information volume; requesting a virtual data volume to update the data blocks with the data; and requesting the virtual protection information volume to store the protection information.

摘要： A method for validating data in a data storage system comprising associating a first data chunk with first check data and storing the first data chunk and the first check data on a first storage device. Additional associated data chunks of the first data and associated additional check data are stored on at least one of the first storage device or one or more additional storage devices. At least a portion of the first check data and at least a portion of the additional check data are stored to a second storage device, which is distinct from the first storage device and the additional storage devices. I/O access to the second storage device is minimized by retaining at least a portion of the first check data and at least a portion of the additional check data in a readily accessible storage medium, during servicing of a first I/O request.

摘要： A plurality of data units with associated timestamps is stored in a time based file system, wherein a timestamp corresponds to a time indicated by a system clock. A time indicated by the system clock is changed while the plurality of data units is being stored. A plurality of epochs is stored in a data structure, wherein an epoch is a period of time between a starting and an ending timestamp selected from the timestamps, and wherein successive epochs have overlapping time periods. The time based file system is reverted to an earlier point in time based on the plurality of epochs stored in the data structure.

摘要： An apparatus, system, and method are disclosed for validating logical volume configuration. A determination module makes a determination of a type of a host operating system of a host computer requesting access to a logical volume. A characterization module characterizes the host type of the logical volume. A compatibility module determines if the logical volume is configured for the host operating system. A mitigation module mitigates the mis-configuration if the logical volume is not configured for the host operating system.

摘要： Provided are a method, system, and article of manufacture for mirroring data between a first site and a second site. Updates to segments of storage at the first site are copied to corresponding segments of storage at the second site. Codes are generated from the segments at the second site and a valid flag is provided for at least one code indicating whether the code for the segment of data is valid. One code is generated from each segment of storage at the first site. An operation is initiated to copy segments from the second site to the first site. A determination is made for segments at the second site as to whether the valid flag for the code for the segment at the second site indicates that the code is valid in response to initiating the copy operation. The valid code for at least one segment in the second site is compared with the code for the corresponding segment at the first site to determine whether to copy the data from the segment at the second site to the first site as part of the copy operation.

摘要： Emulation of a small computer system interface (SCSI) library storage is provided in a virtual data storage subsystem having an automated tape library. This allows the ability to access or store a logical volume of data. Medium changer commands as used in SCSI and other open system interfaces are mapped to library function commands as commonly used in an enterprise server environment. This allows full transparent usage of virtual tape storage available in the enterprise server environment as open system storage.

摘要： Tokens corresponding to data units written to a rewritable file system are stored, where an ordering relationship is maintained among the tokens, where the ordering relationship is such that a first token corresponding to a first data unit is of a lesser numerical value in comparison to a second token corresponding to a second data unit, and where the first data unit is written at an earlier point in time in comparison to the second data unit. The rewritable file system is reverted to an indicated point in time based on the ordering relationship that is maintained among the stored tokens.

摘要： A file system driver stored in a computational device receives a request to provide access to a snapshot of a rewritable file system at a selected point in time, wherein a plurality of tokens corresponding to a plurality of data units are stored in the rewritable file system, and wherein an ordering relationship is maintained among the plurality of tokens. The file system driver determines a token corresponding to the selected point in time based on the ordering relationship. A virtual subdirectory name is generated corresponding to the determined token. A virtual subdirectory is created with the generated virtual subdirectory name, wherein the virtual subdirectory is a subdirectory of a root directory. The snapshot is accessed via the subdirectory.
