An artifact repository can be queried for a set of different pre-existing presentation artifacts based on requirements and constraints of a presentation event to produce a query result. The query result can comprise a set of presentation artifacts suitable for satisfying at least a portion of the requirements and constraints. The querying can match the artifact specific metadata against the requirements and constraints to produce the query result. An agenda comprising a set of different agenda items can be automatically constructed utilizing the query result. Each of the different agenda items can occupy a time slot of the presentation event. Creation of agenda items can be a non-manual effort automatically determined by a computing device in a data driven manner given the requirements, the constraints, and the pre-existing presentation artifacts of the artifact repository. Resources for the different agenda items can be automatically booked.

A storage management application determines that a source virtual tape requires reclamation, identifies all block addresses for active data of a source virtual tape and sorts the block addresses in an ascending order, identifies a target virtual tape which has sufficient free capacity to store the active data of said source virtual tape and the last written block address on said target virtual tape, and sends a command to the VTL-system instructing it to perform reclamation including information about said source and said target virtual tape, the sorted list of block addresses denoting active data on the source virtual tape and the starting block address on the target virtual tape. The reclamation logic references the active data host blocks of said source volume to said target virtual tape starting at said starting block address by just updating the host block to disk block mapping table.

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.

Data for deduplication is received. The received data is deduplicated if selected conditions corresponding to the deduplication are satisfied, wherein the selected conditions include a deduplication ratio, a data deduplication threshold, and a data quiescence measure. Deduplication of the received data is discontinued if the selected conditions corresponding to the deduplication are not satisfied.

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.

Embodiments of the disclosure relate to a biosample cartridge that includes storage slots for holding biosample plates. The cartridge has the same form factor as data tape cartridges to allow the cartridge to be handled by the same robotic mechanisms that handle data cartridges in an automated tape library. One aspect of the disclosure concerns a biosample storage cartridge that has a movable door to provide access to inside the cartridge and a plate holder disposed inside the cartridge. The plate holder includes a plurality of slots for receiving biosample plates that are scanned and processed by the automated tape library.

Embodiments of the disclosure relate to a biosample plate that includes a memory component for storing information related to the biosample, biosample plate and biosample analysis data, and a wireless communication interface for transferring information to and from the biosample plate. The biosample plate may be used with an analyzing and data recording system such as an electromagnetic tape drive. The disclosed biosample plate facilitates the correlation between a large number of biosample plates and data as data remains with the corresponding biosamples both when the biosample plates are in use and when they are in storage. The wireless communication interface may comprise an antenna disposed in a biosample plate for data transmission to and from the biosample plate by radio signals.
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.
