Researchers Submit Patent Application, "Efficient Distribution and Selection of Storage Media in a Storage Medium Library", for Approval

June 12, 2014



By a News Reporter-Staff News Editor at Politics & Government Week -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventors Hasegawa, Tohru (Sagamihara, JP); Hirata, Takamasa (Tokyo, JP); Imai, Naoki (Yokohama, JP); Kamiya, Masanori (Sagamihara, JP); Oishi, Yutaka (Kawasaki, JP), filed on February 14, 2013, was made available online on May 29, 2014.

The patent's assignee is International Business Machines Corporation.

News editors obtained the following quote from the background information supplied by the inventors: "Embodiments of the inventive subject matter generally relate to the field of mass storage systems, and, more particularly, to the efficient movement of storage media in a storage medium library.

"Mass storage systems are utilized in scenarios where large amounts of data are handled, such as data centers. Although many of these mass storage systems utilize a large number of individual storage media and are designed to function with little human intervention, movement of storage media within these systems can be slow and inefficient. Reducing the amount of time taken to move storage media can reduce the amount of time a particular software program is idle waiting for the movement to complete, and reducing the amount of movement can positively impact the cost of electricity."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "Embodiments of the inventive subject matter include a method in which a distribution is determined for a plurality of distributable components within a storage medium library. It is also determined that the plurality of distributable components are not currently distributed across the storage medium library in accordance with the distribution. Responsive to the foregoing determinations, a set of one or more commands is issued to move one or more of the plurality of distributable components to different locations of the storage medium library in accordance with the distribution.

"Embodiments of the inventive subject matter include a method in which the location of a drive in a storage medium library is determined. Responsive to said determination, it is determined whether a storage medium that is available to be read from or written to is located within first distance from the drive. If it is determined that the storage medium is not located within the first distance from the drive, it is determined whether the first storage medium is located within a second distance from the first drive. The second distance is farther than the first distance. If it is determined that the storage medium is located within the first or second distance from the drive, the storage medium is made available to be read by or written to by the first drive.

BRIEF DESCRIPTION OF THE DRAWINGS

"The present embodiments may be better understood, and numerous objects, features, and advantages made apparent to those skilled in the art by referencing the accompanying drawings.

"FIG. 1 depicts the interactions between a library manager and a shuttle complex to distribute scratch cartridges within the tape library.

"FIG. 2 depicts a first flowchart of example operations a library manager can perform to distribute scratch cartridges to a set of interconnected library strings in a tape library.

"FIG. 3 depicts a second flowchart of example operations a library manager can perform to distribute scratch cartridges to a set of interconnected library strings in a tape library.

"FIG. 4 depicts a tape library system that is designed to efficiently find an available tape drive and scratch cartridge, minimizing the distance traveled by a scratch cartridge.

"FIG. 5 depicts a flowchart of example operations a library manager can perform to find an available tape drive and scratch cartridge.

"FIG. 6 depicts a tape library system that is designed to distribute scratch cartridges in conjunction with the servicing of other requests.

"FIG. 7 depicts a flowchart of example operations a library manager can perform to distribute scratch cartridges while servicing other requests.

"FIG. 8 depicts an example computing system with a library manager."
