Abstract:
A storage library for recording and retrieving information from storage media cartridges each having a label side includes a front side having an opening. Left and right slots are disposed proximate the left and right sides of the storage library for holding the storage media cartridges. The slots and the storage media cartridges are oriented so that each label side of the storage media cartridges is visible to an operator through the opening. Each of the slots are accessible to the operator via the opening for the operator to access the storage media cartridges being held by the slots. A media drive is disposed proximate the back side of the storage library and is operative to receive a storage media cartridge through a port. A robotic mechanism is disposed between the slots and is operative to move the storage media cartridges between the slots and the media drive.
Abstract:
A system and method for distributing electrical power to an automated robotic device for transporting media cartridges in a data storage library. The system and method include a power distribution rail assembly having first and second electrically conductive rails for providing electrical power to the automated robotic device, the first and second rails provided with opposite electrical charges. The system and method also include multiple contacts on the automated robotic device for making electrical contact with the first and second rails. The contacts include a first pair of contacts for making electrical contact with the first rail and a second pair of contacts for making electrical contact with the second rail. At least one of the first pair of contacts and at least one of the second pair of contacts maintain contact with the first and second rails, respectively, as the automated robotic device moves in the data storage library.
Abstract:
A secure gateway multiple automated data storage system sharing is provided. Data is transmitted from a first data storage unit within a first automated data storage system to a second data storage unit. A request is then received from a second data storage system for the second data storage unit. The second data storage unit is then transported to the second data storage system.
Abstract:
A mechanism is provided for storing self-defining data and mapping elements with either a fixed set of allowed structures or types or with the structures and types determined by rules. Recovery is enhanced by the use of backward and forward pointers between data and mapping elements for the data elements in the order written by the management algorithm. Recovery is also enhanced by the use of companion pointers with metadata. The companion pointers may include pointers to data or mapping elements that are part of the same structural grouping. The metadata may describe the structural grouping. The metadata may also include pointers to the previous and/or next versions of the same elements. Recovery of the data and/or mapping structures is achieved by the reverse application of the management algorithm.
Abstract:
The present invention is an automated storage library suitable for rack-mount and desktop installations. Storage media cartridges and a robotic mechanism that transport the storage media cartridges internal to the library are mounted on a moveable drawer. With the drawer at an internal position, the robotic mechanism transports the storage media cartridges between cartridge slots mounted on the drawer and read-write media drives and other cartridge handling devices not mounted on the drawer. The drawer is capable of moving through an opening in the storage library housing to an external position where the storage media cartridges and the robotic mechanism are readily accessible. At the external position, the storage media cartridges can be inserted and removed from the cartridge slots. The drawer may be detachable from the housing to allow unobstructed access to the components housed in the interior of the storage library.
Abstract:
A storage system and method for storing delta difference data indicative of the differences between new data and old data. A data transferring unit has copies of old data and new data. The data transferring unit compares the new data with the old data to determine delta difference data indicative of the differences between the new data and the old data. A target storage device having a copy of the old data receives the delta difference data from the data transferring unit. The target storage device stores the delta difference data and may then determine the new data by merging the old data with the delta difference data. The target storage device transmits the determined new data to a data receiving unit upon request. The method and system may be used with peer-to-peer remote copy (PPRC) storage system and storage area network (SAN) storage system.
Abstract:
A system according to the invention for mounting multiple media drives includes a housing and multiple modules that are insertable into and removable from the housing. Each module is adapted to hold a media drive. Furthermore, the system includes a resilient layer disposed between the housing and the modules when the modules are inserted into the housing for attenuating shocks and vibrations. The resilient layer includes a slot for inhibiting transmission of shocks and vibrations between at least two of the modules.
Abstract:
Reducing alignment errors between a read element and corresponding write elements permits narrower data tracks and, hence, greater data density on magnetic tape. A method for manufacturing a thin film tape head having multiple write elements and at least one read element corresponding to each write element is provided. Excess material is trimmed from each write element to align the write element with corresponding read elements. The excess material may be track trimmed using a focused ion beam.
Abstract:
A system for identifying and managing information stored in a plurality of physical volumes (e.g., tape cartridges) in an information storage system includes a plurality of labels. Each label is configured for physical attachment to a physical volume and includes an electromagnetic transducer for storing data associated with the physical volume and/or the information contained therein. The means for storing is non-volatile, re-writable, and readable without requiring physical contact with the label.
Abstract:
The present disclosure provides a movable cabinet and an energy storage apparatus. The movable cabinet includes a concrete main body and a flame retardant material layer. The concrete main body includes a plurality of walls forming an accommodating space. The flame retardant material layer is disposed on one or more inner surfaces of the plurality of walls in the accommodating space.
