摘要： In one embodiment, a method for accessing host data records stored in a VTS system includes receiving a mount request to access at least one host data record, determining a SLBID corresponding to the requested host data records, determining a PBID that corresponds to the SLBID, accessing a physical block on a sequential access storage medium corresponding to the PBID, and outputting at least the physical block corresponding to the PBID without outputting an entire logical volume that the physical block is stored to. According to another embodiment, a VTS system includes random access storage, sequential access storage, support for at least one virtual volume, a storage manager having logic for determining a PBID that corresponds to a SLBID, and logic for copying a portion of a logical volume from the sequential access storage to the random access storage without copying the entire logical volume.

摘要： An embodiment of the invention comprises a virtual tape system supporting at least one Write Once Read Many (WORM) logical tape and at least one read-write logical tape, comprising a processor configured to a first task and/or a second task. The first task initializes a new logical data object from a single pool of at least two logical data objects, with the new logical data object bound with a member of a media type group consisting of a WORM data object or a read-write data object. The second task reuses one of the logical data objects without manual ejection and reinsertion. The reuse may include the processor configured to cycle the logical data object through a scratch pool as a selected scratch logical data object and mount the selected scratch logical data object with a write from beginning of tape command to bind at least one data attribute to the WORM data object.

摘要： A method to write information to one or more information storage media disposed in a data storage and retrieval system comprising host adapters capable of data compression and information storage devices capable of data compression. The method establishes a storage medium usage threshold and determines the actual storage media usage level for the data storage and retrieval system. The method then determines if the actual storage media usage level is greater than the storage medium usage threshold. If the actual storage media usage level is greater than said storage medium usage threshold, then the method enables use of information storage device data compression. Alternatively, if the actual storage media usage level is not greater than said storage medium usage threshold, then the method disables use of information storage device data compression.

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.

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 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, and an incrementing token.
摘要翻译：数据存储系统存储逻辑数据对象，每个逻辑数据对象由逻辑标识符标识。控制被配置为向逻辑数据对象分配唯一的WORM（一次读取多个）标识符，并且将与逻辑标识符相关联的唯一WORM标识符存储在由控制器维护的数据库中以便被持久化。数据存储被配置为使用具有唯一WORM标识符的报头来写入逻辑数据对象。为了允许将逻辑数据对象从控制外部访问，控制需要将逻辑数据对象的头部中的唯一WORM标识符与逻辑对象的持久性数据库的唯一WORM标识匹配。独特的WORM标识符由与至少包括逻辑数据对象的逻辑标识符和增量令牌的至少包含字段相关的校验和散列值形成。
