Abstract:
A robotic data storage library comprising a virtual port and a method for providing a virtual port for a robotic data storage library are disclosed. The virtual exit port, for example, comprises one or more storage locations of the library that are defined as a virtual port. In one embodiment, for example, the virtual port comprises a virtual exit port for holding a data storage element that is to be exported from the library. In this embodiment, for example, the virtual exit port is defined prior to the library receiving a command to export a data storage element. In another embodiment, the virtual port comprises an entry port, an exit port or an entry/exit port. In yet another embodiment, a method for transferring a data storage element directly between an actual port (entry and/or exit) of a robotic data storage library and another location within the robotic data storage library not defined as the virtual port is disclosed.
Abstract:
A storage unit including a frame that defines a storage unit interior space, at least one storage media support structure capable of removably supporting a plurality of storage elements wherein the storage media support structure is adapted to provide a communicating path between the storage elements and the storage unit. The storage media support structure is capable of moving between a retracted position wherein substantially all of the storage elements are within the interior space and an extended position wherein substantially all of the storage elements are external to the interior space. Power and communication are provided to the storage media support structure when the storage media support structure is at or between the retracted and extended positions the power and communication is uninterrupted.
Abstract:
Disclosed is a method and apparatus for a variable media tape based storage system for storing, retrieving, and communicating data. The system includes at least one media element having a compatible relationship with one of a plurality of drives for storing and receiving data. The at least one media element configured to operate with the at least one drive as a functional pair is considered a loaded drive. The storage system also includes switch and mapping system, which in one embodiment could be an interface bridge processor, operatively linked to each of the plurality of drives. Finally, the storage system adapted to alter at least one received and accepted tape library command from positioning a target storage tape article for use with a target tape drive to selecting one of the loaded drives via the interface bridge processor. The interface bridge processor can be adapted to receive data in a streaming protocol to be saved on the target storage tape article by the target storage drive and convert the streaming protocol to a different protocol to save the data on the physically selected loaded drive.
Abstract:
The present invention provides an apparatus and method for monitoring the read/write reliability of data storage device contained within a data cartridge library system (100). The data cartridge library system includes multiple player/recorder devices (22, 24, 26, 28). In accordance with one aspect of the invention, the data cartridge library computer queries a player/recorder device after it has been involved in a read/write operation. In one embodiment, the information queried is the Write and/or Read ECC Error Rates. In another embodiment, the Write and/or Read ECC Error Rates are assessed to determine whether the subject player/recorder device is experiencing read/write problems and whether remedial action is warranted (18). In another embodiment, the subject player/recorder device is tested using a certified test cartridge and a known data pattern. In another aspect of the invention, preventive maintainance of the data cartridge library system includes one of the player/recorder devices writing a known data pattern to a certified test and the same device (18).
Abstract:
An apparatus and associated method that contemplate obtaining a server in selective communication with an archive storage controller (ASC) via a computer network, the ASC having access to a plurality of removable storage mediums (RSMs); storing data in the server; creating a logical storage volume in the ASC that has a logical relationship to the data stored in the server; and after the creating step, and without communication between the server and the ASC via the computer network, selecting at least one of the RSMs and dedicating the selected at least one RSM for retaining only data that is stored in the logical storage volume.
Abstract:
Disclosed is a method and apparatus for an alignment system for use in a data storage system for enabling numerous contact cycles between two surfaces in a robust manner. The system includes a first and a second surface each having at least two contact zones. Each of the contact zones comprise either a conductive spring or a conductive pad. Each of the conductive springs is adapted to engage a corresponding conductive pad, wherein the engaging location on the pad is substantially flat, to form at least one closed circuit when the first and the second surfaces are aligned and are in contact. A continuity confirmation device can further be used to confirm the closed circuit.
