摘要： A hybrid data storage system is one which has data storage clusters of different types. In a hybrid data storage system, at least one first data storage cluster is configured to store data and has high data storage capacity; and at least one second data storage cluster is configured to store data and has lower data storage capacity than the first cluster. The data is initially replicated and stored by at least one first and at least one second data storage cluster. The method identifies a portion of the stored initially replicated data of at least one second data storage cluster as “pinned”; continues to store the pinned initially replicated data; and selectively removes non-pinned initially replicated data from the second data storage cluster(s) to account for the capacity difference.

摘要： A data storage system stores logical data object(s), each identified by a logical identifier. A control is configured to assign a unique WORM (Write Once Read Many) identifier to the logical data object, and stores the unique WORM identifier as associated with the logical identifier, in a database maintained by the control so as to be persistent. Data storage is configured to write the logical data object with a header with the unique WORM identifier. The control, in order to allow the logical data object to be accessed externally to the control, requires matching the unique WORM identifier in the header of a logical data object to the unique WORM identifier of the persistent database for the logical object. The unique WORM identifier is formed of a checksum hash value related to nonce fields comprising at least the logical identifier of the logical data object, an incrementing token, and a time stamp.

摘要： A method to export and then import a logical volume with assigned storage attributes, from a first information storage medium to a second information storage medium. The method maintains a logical volume in a first information storage medium. The method assigns one or more first storage attributes to that logical volume. The method further includes forming an import list logical volume. The method further includes defining a plurality second storage attributes. The method further includes importing the logical volume, and the assigned first storage attributes, into a second information storage medium. The method then determines if the import list logical volume specifies use of one or more second storage attributes. If the import list logical volume specifies use of one or more second storage attributes, then the method assigns to the logical volume those one or more second storage attributes.

摘要： A method and apparatus for handling multi-volume datasets in a tape storage system are disclosed. In response to a write request for a multi-volume dataset, the information of the multi-volume dataset are captured by intercepting and deciphering a set of volume mount commands. Otherwise, the information of the multi-volume dataset are captured by snooping header information from a previous volume listed in a header of the multi-volume dataset. A chain of logical volume names that belongs to the multi-volume dataset is then built. Finally, the chain of logical volume names is then stored in a chain database.

摘要： A method to maintain information by assigning one or more storage attributes to each of a plurality of logical volumes. The method writes a first portion of a dataset to a first logical volume. The method assigns one or more storage attributes to that first logical volume. When the logical end of volume for the first logical volume is approaching, Applicants' method mounts a second logical volume, and continues writing the dataset to that second logical volume. The method assigns the same one or more storage attributes to the second logical volume.

摘要： An apparatus, system, and method are disclosed for selecting a source cluster in a distributed storage configuration. A measurement module measures system factors for a plurality of clusters over a plurality of instances. The clusters are in communication over a network and each cluster comprises at least one tape volume cache. A smoothing module applies a smoothing function to the system factors, wherein recent instances have higher weights. A lifespan module calculates a mount-to-dismount lifespan for each cluster from the smoothed system factors. A selection module selects a source cluster for accessing an instance of a specified volume in response to the mount-to-dismount lifespans and a user policy.
