    摘要: Retention management for data stored in data blocks on a tape is provided. A block mapping table has entries each of which include an expiration date for data blocks stored on the tape. The entries of the block mapping table may be sorted in accordance with at least one sorting criterion. Data blocks on the tape are rearranged according to the block mapping table. The block mapping table is then stored, either on the tape or in a memory associated with the tape.

    摘要: A secure data system employs a storage media and a storage drive. A storage media identification key is embedded in a non-user modifiable area of the storage media and associated with data recorded on the storage media. The storage drive includes a memory having a storage drive identification key embedded therein. In operation, the storage drive allows access to the data recorded on the storage media based on a validation by the storage drive of the storage drive identification key as a function of the storage media identification key.

    摘要: A method, system and article of manufacture for the storing convolution-encoded data on a redundant array of independent storage devices (RAID) is described. The convolution-encoded data comprises error correction coded data to eliminate the need for parity as used in conventional RAID data storage. The number of storage devices may vary to accommodate expansion of storage capacity and provide on demand storage.

    摘要: A method to store data is disclosed. The method provides a plurality of data storage media, an automated data library comprising one or more data storage devices, a first plurality of storage cells, and a robotic accessor. The method further provides a storage vault comprising a second plurality of storage cells but no data storage devices. The method selects the (i)th data storage medium and sets the (i)th data state, where that (i)th data state is selected from the group consisting of online, offline, and vault. If the method sets the (i)th data state is set to online, then the method mounts that (i)th data storage medium in one of the data storage devices. If the method sets the (i)th data state to offline, then the method removeably places the (i)th data storage medium in one of the first plurality of storage cells. If the method sets the (i)th data state is set to vault, then the method places the (i)th data storage medium in one of the second plurality of storage cells.

    摘要: A data storage system includes a data storage array configured for de-duplication of duplicate data therein by: identification of a plurality of portions of data; a comparison of each portion of the data to identify duplicate data and identification of a link associated with each duplicate data; a determination of whether a Hamming link-separation-distance of the identified link is greater than twice a Hamming radius of an error correction code in the data storage system; and replacement of the duplicate data with the identified link when it is determined that the Hamming link-separation-distance is greater than twice the Hamming radius.

    摘要: A media passport system including a radio frequency identification (RFID) transponder attached to a removable medium a plurality of RFID readers installed in rooms, wherein each RFID reader has a unique identification (ID), and a security server connected to the plurality of RFID readers via a network. The security server hosts a zone-table including a unique ID information of the removable medium, and a zone information determined as a subset of the unique IDs of the plurality of RFID readers. Based on this the security server sends an alarm when a removable medium is transported inside or outside a zone.

    摘要: Provided are a method, system, and article of manufacture for credit depletion notification for transmitting frames between a port pair. Credits indicate a number of outstanding frames a first device may transmit to a second device. The credits are decremented in response to transmitting a frame to the second device. The credits are incremented in response to receiving a ready code from the second device indicating that the second device processed the transmitted frame. A determination is made as to whether additional credits are needed for communicating frames from the first device to the second device. A credit depletion notification is sent to the second device in response to determining that the additional credits are needed for communication with the second device.
