| 20080270106 | EMULATED TAPE-BASED STORAGE MEDIA - A controller, system, method and computer program for emulating one or more tape-based storage devices using non-tape based physical data storage media. The controller is adapted to generate a data set for indicating an available capacity of the one or more emulated tape-based storage devices, the data set includes capacity data for indicating a respective available capacity of the one or more emulated tape-based storage devices based on an available capacity of the non-tape-based physical data storage media. The controller is also adapted to provide access to data stored on the non-tape based physical data storage medium using tape-based media command and the data set, and to dynamically update the capacity data of the data set in response to a change in the available capacity of the non-tape-based physical data storage media. | 10-30-2008 |
| 20090077309 | DATA TRANSFER - A virtual tape library including a module which is operable to issue input and output commands to a tape drive connected to the virtual tape library, wherein an input command is a command to write data to a tape connected to the tape drive and an output command is a command to read data from a tape connected to the tape drive. | 03-19-2009 |
| 20100192050 | UPDATING SEQUENTIAL DATA - Disclosed is a storage apparatus comprising a data store; a data input; and a data processor arranged to: receive from the data input a block of data to be stored at an append point after sequential data comprising one or more stored blocks of data; retrieve an integrity measure, of one or more stored integrity measures that are associated with one or more respective points in the sequential data, said retrieved integrity measure being associated with a point at or preceding the append point; calculate a new integrity measure using the received block of data and the retrieved integrity measure; and store the received block of data and the new integrity measure in the data store, in addition to at least one stored integrity measure that is associated with a point in the data at or preceding the append point. | 07-29-2010 |
| 20110173407 | DATA STORAGE SYSTEM - A data storage system comprising a server computer and a data storage medium. The server computer includes an interface, such as an iSCSI interface, for communicating with a host computer. In response to receiving data from the host computer, the server computer determines whether or not the host computer has access to a virtual data storage device. If the host computer does not have access to a virtual data storage device, the server computer provides a virtual data storage device for access by the host computer, the virtual data storage device employing at least a portion of the data storage medium such that data stored to the virtual data storage device are stored to the portion of the data storage medium. | 07-14-2011 |
