    摘要: Methods and apparatus are provided for dynamically compressing categories in a data storage library. In one embodiment, the method includes retrieving an identification of a first category in the data storage library, the first category being a last-compressed category. Next, an identification number of a first order of the first category is retrieved, the first order being a last compressed order. Compression is resumed of orders in the first category with an order next following the first order and continued with additional orders in the first category. If a predetermined amount of time has elapsed, the identification of the first category and the identification number of the order of the first category being compressed are stored. If, however, the predetermined amount of time has not elapsed and compression of the first category is complete, compression of a second category is begun.

    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 write information to two virtual tape servers. The method writes a file to a virtual host device disposed in a first virtual tape server, where the virtual host device comprises an adjustable bandwidth. The method queues a job to copy the file to a second virtual tape server, determines the age of the copy job, and copies that file to the second virtual tape server. The method sets an age threshold, and determines if the copy job age is greater than that age threshold. If the copy job age is greater than the age threshold, then the method decreases the adjustable bandwidth, if not, the method restores the adjustable bandwidth.

    摘要: Provided are a method, system, and program for managing data in storage units. Storage pool information indicates an assignment of a plurality of storage units to a plurality of storage pools, wherein each pool is assigned zero or more storage units, wherein data associated with one storage pool is stored in a storage unit assigned to the storage pool, wherein the storage pool information for each pool indicates a threshold and target storage pool, and wherein the target storage pool is capable of being different from the storage pool. One storage unit associated with a source storage pool is selected and a determination is made of the threshold from the storage pool information for the source storage pool. A determination is made of whether the selected storage unit satisfies the determined threshold and if the selected storage unit satisfies the determined threshold, then a target storage unit in the target storage pool is selected if the storage pool information for the source storage pool indicates a target storage pool different from the source storage pool. Data from the selected storage unit is copied to the selected target storage unit.

    摘要: A method and system for shredding data within a data storage subsystem is disclosed. According to one embodiment, a method is provided of continually shredding data within a data storage subsystem in which all the data of a first storage element is made permanently unreadable followed by the performance of a data shred process. In the described data shred process, second storage element is first selected (e.g., from plurality of candidate or potential storage elements), which includes a first storage object to be preserved and a second storage object to be shredded. Once the second storage element is selected, data of the first storage object is stored/copied within the first storage element. Thereafter, all data of the second storage element is rendered permanently unreadable.

    摘要: An apparatus, system, and method are disclosed for recalling a logical volume from a mountable media for use in a virtual tape server. The apparatus includes a receiving module, a queuing module, and an optimizer module. The receiving module receives recall requests for logical volumes stored in a mountable media such as a tape cartridge. The queuing module places the requests in a queue to be processed in turn. The optimizer module reorders the queue based on one or more optimization rules in order to process the recall requests more efficiently.
