Patent Issued for Staged Storage Magazine Install in a Storage Library

June 24, 2014



By a News Reporter-Staff News Editor at Information Technology Newsweekly -- From Alexandria, Virginia, VerticalNews journalists report that a patent by the inventors Plutt, Daniel James (Superior, CO); Woodbury, Matthew David (Westminster, CO); Mynatt, Blake Jonathan (Broomfield, CO), filed on May 16, 2012, was published online on June 10, 2014.

The patent's assignee for patent number 8749913 is Oracle International Corporation (Redwood City, CA).

News editors obtained the following quote from the background information supplied by the inventors: "Storage library systems are often used by enterprises and the like to efficiently store and retrieve data from storage media. In the case of some storage libraries, the media are data cartridges (e.g., tape cartridges) that are typically stored and indexed within a set of magazines. When particular data is requested, a specialized robotic mechanism finds the appropriate cartridge, removes the cartridge from its magazine, and carries the cartridge to a drive that is designed to receive the cartridge and read its contents. Some storage libraries have multiple drives that can operate concurrently to perform input/output (IO) operations on multiple cartridges.

"Ensuring proper functioning of the storage library involves secure and accurate positioning of components, including magazines. To maintain secure and accurate positioning, traditional data storage systems are typically designed to discourage interactions with those components, except by trained support personnel. For example, installation and/or removal of magazines may involve specialized tooling, coupling with relatively complex drawer railing mechanisms, etc."

As a supplement to the background information on this patent, VerticalNews correspondents also obtained the inventors' summary information for this patent: "Among other things, systems and methods are described to facilitate relatively simple installation and/or removal of magazines in context of modules of a data storage system. For example, it may be desirable to fill a magazine with data storage cartridges and to install the full magazine into the data storage system. Embodiments use staged structural features to sequentially guide and align the magazine into a desired position in a data storage system. The structural features are designed to facilitate relatively simple installation while providing sufficiently accurate and secure positioning.

"According to one set of embodiments, a storage system is provided. The system includes a magazine configured to hold cartridges in slots and to be installed in a module by slideably engaging magazine engagement structure of the magazine with module engagement structure of the module in an installation dimension. The magazine engagement structure includes: a first portion of the magazine engagement structure engageable to interface with the module engagement structure while permitting a first degree of motion in a first dimension and a second degree of motion in a second dimension, wherein the first dimension, the second dimension, and the installation dimension are different dimensions; a second portion of the magazine engagement structure engageable to interface with the module engagement structure while permitting only a third degree of motion in the first dimension that is more restrictive that the first degree of motion in the first dimension; and a third portion of the magazine engagement structure engageable to interface with the module engagement structure while permitting only a fourth degree of motion in the second dimension that is more restrictive that the second degree of motion in the second dimension.

"According to another set of embodiments, a method is provided. The method includes: engaging a first portion of magazine engagement structure of the magazine with module engagement structure of the module in such a way that permits a first degree of motion in a first dimension and a second degree of motion in a second dimension that is different from the first dimension; first slideably engaging the magazine with the module in an installation dimension thereby engaging a second portion of the magazine engagement structure with the module engagement structure to progressively restrict motion of the magazine in the first dimension, the installation dimension being different from the first and second dimensions; and second slideably engaging the magazine with the module in the installation dimension thereby engaging a third portion of the magazine engagement structure with the module engagement structure to progressively restrict motion of the magazine in the second dimension, such that, after second slideably engaging the magazine with the module, the magazine is substantially restricted from moving in the first and second dimensions. In some such embodiments, the method further includes: third slideably engaging the magazine with the module in the installation dimension until a full install position is reached; and securing the magazine from moving in the installation dimension when it is in the full install position, such that, in the full install position, the magazine is substantially restricted from moving in the first, second, and install dimensions."
