摘要:
An automated storage system includes a media storage facility, which may take the form of an automated storage library or shelf system. The media storage facility includes a plurality of individual medium slots and a plurality of superset slots. The facility further includes at least one mechanism for accessing individual media and at least one mechanism for accessing supersets of media. Individual media located in a superset remain accessible on an individual basis in addition to being accessible as part of the corresponding superset.

A method, system and program for generating parity in a data storage system are provided. The invention comprises organizing an incoming data block into a specified number of data stripes and cascading the data stripes into a parity creation mechanism. The parity creation mechanism creates a specified number of parity stripes based on the data stripes, wherein the number of parity stripes is independent of the size of the data block. The parity creation mechanism can operate offline to reconstruct lost data stripes and parity stripes without using critical system resources, wherein the number of devices required for stripe reconstruction is less than the combined number of data stripes and parity stripes.

An automated modular storage library is formed by a plurality of available library elements. Each available library element is selected from a predetermined limited subset of library elements made available for library assembly. This creates a library that is modular by restricting the library elements used during assembly to the limited subset of library elements. According to a partial audit principle, an area where an intervention is to be performed may be physically separated prior to the intervention. After the intervention, the partial audit is conducted in a separated area where the intervention occurred, as the remainder of the library was protected during the intervention by the physical separation.

A drawer slide for coupling a drawer to a cabinet is provided. A drawer rail is C-shaped. An intermediate rail is partially housed within the drawer rail and includes a web and first and second legs which are connected to the web by two folds in the material used to form the intermediate rail. A flange extends from the first leg toward the second leg. Bearings housed in bearing cages placed between the rails allow sliding movement therebetween. A cabinet rail is partially housed within the intermediate rail and includes an upright wall and a flange extending away from the upright wall and toward the first leg. Ball and roller bearings housed in bearing cages couple the flanges. Grooves in the flanges are engaged by the ball bearings. Roller bearings housed in bearing cages couple the web of the intermediate rail and the flange of the cabinet rail, as well as the second leg of the intermediate rail and the upright wall of the cabinet rail.
摘要:
A system and method of recognizing resources of a computer comprising a system serial number and a broken hardware unit comprising a non-volatile memory unit and enablement definition data relating to functions of the broken hardware unit, wherein the method comprises starting the computer; entering a serial number in a read/write non-volatile memory field of the non-volatile memory unit; reading the read/write non-volatile memory field; and matching the serial number of the read/write non-volatile memory field with the system serial number. The method may further comprise detecting failure of the broken hardware unit after the starting of the computer. Preferably, a reading that the serial number of the read/write non-volatile memory field matches with the system serial number permits acceptance of the enablement definition data of the broken hardware unit.

A method and system for sharing data and interrogating data include establishing a level of trust between mutually mistrusting entities so that data may be shared therebetween based on the level of trust. The method and system include interrogating data provided from one of the entities to the other entity without the receiving entity having complete access to the data associated therewith.

Security is provided for a data set stored in a data storage canister. The data set has a data size when received for storage within the canister. At least one data security operation is performed on the received data set to generate secure data having a secure data size that may be different than the set data size. The secure data is stored on at least one data storage device within the canister. Any information about the secure data size is kept from the data producer sending the data set for storage.
摘要:
A method for storing digital data in a virtualization storage system which includes the step of creating a virtual storage volume and communicating the location of the virtual storage volume to a storage subsystem. The storage subsystem identifies a mapping type between the virtual volume and at least one virtual volume-related physical device and then creates virtualization metadata describing the virtual volume, the mapping type, and the virtual volume-related physical device. The storage subsystem mediates the storing of at least a portion of the virtualization metadata on the virtual volume-related physical device as device stored metadata. A portion of the stored virtualization metadata is provided to then one or more using systems which utilize this metadata to update the virtual volume information contained therein. A virtualization storage system implements one or more steps of the methods of the invention.

摘要:
A method and a system for alternatively activating, in a data processing system, a replaceable hardware unit and providing a predetermined set of functional capabilities for configuring the data processing system to allow selectively electronically enabling at least a subset of its functional capabilities. Initially a replaceable hardware unit is provided to the data processing system, then its type is determined. If the replaceable hardware unit is of a first type, the subset of functional capabilities to be electronically enabled is determined. Alternatively, if the replaceable hardware unit is of another type, the entire functional capabilities of the replaceable hardware unit are enabled.
