摘要:
A media cartridge including a first substantially rectangular surface, a second substantially rectangular surface, and one or more side surfaces, where the first substantially rectangular surface and the second substantially rectangular surface are connected by the one or more side surfaces. Further, a disk drive assembly is enclosed by the first substantially rectangular surface, the second substantially rectangular surface, and the one or more side surfaces. In addition, the media cartridge includes a cooling component is configured to cool the disk drive assembly.
摘要:
A media cartridge for use with data storage libraries. The cartridge includes a housing having an opening through which a carrier tray can be loaded and extracted to reveal a media element. A number of baffles are included to limit exposure of the media elements to contamination.
摘要:
A media drive system includes a housing and a drive unit at least partially disposed within the housing. A media handler arrangement defines a plurality of queuing positions for media objects, and a receiving area within the housing receives storage units defining at least one other queuing position. The drive system reduces latency through the use of the queuing positions to speed transfer and access to media objects.

摘要:
A method, computer program product, and data processing system for continuously writing new data to a redundant array of independent storage devices without interrupting the writing of new data to the array to reconstruct missing data from a failed device or failed media is disclosed. A fault-tolerance scheme using multiple independent parity values is used to record data to the array. In the event that one of the volumes in the array fails, the remaining volumes continue being written to, but with fewer data or parity values being employed. The failed volume can then be reconstructed following the completion of writing the media set currently being written.

This data storage subsystem creates multiple virtual storage devices on demand, which are available to any and all of the system's host data processors. The subsystem utilizes a plurality of tape devices and automated tape libraries with the tape devices connected to a plurality of data processors via a high-speed network. A set of software components, the Network Storage Manager (NSM) controls all system operations. Depending upon the requested storage performance, one or more tape devices are assigned to a virtual device. Data stripping across multiple tape devices allows the storage bandwidth of a virtual device to be changed on demand. The overall capacity and performance of the subsystem is scalable by adding or removing storage devices. The NSM system controller contains a plurality of software elements including: Resource Allocation, Resource Configuration, Resource Management, and Security Management modules. The use of a networked storage manager enables the storage devices to be managed as a pool and yet be attached directly to the network as individual resources. The NSM also provides the mechanism for the enterprise management to control tape device allocation and configuration as well as other functions, such as tape cartridge movement, data migration and data security.

A method to control the inside environment of a cartridge is disclosed. The method includes providing a cartridge having a first chamber for the data storage media and a second chamber for material to control contaminants inside the cartridge. A selectively openable structure permits communication of the air within the first chamber to the material in the second chamber to decontaminate the first chamber.

The removable media management system operates with a manual, an automated, or a combination of subsets of manual and automated library system to store and retrieve media cartridges for an associated plurality of drive elements. This system enables the use of a plurality of types of media within the single monolithic cartridge library system and a corresponding plurality of drive elements associated with said library system. Thus, each drive element has associated therewith a number of object storage locations within the library system which contains media of a form and content that matches the drive element. The removable media management system maps the correspondence between object storage location, media type, designated drive element in a manner such that the single library is partitioned into subsets for the user, i.e., the removable media management system provides the capability to define subsets of media types which have consistent mechanical and electrical characteristics, but can vary in data management attributes. This enables the user to transition to another media on an incremental basis, since a single drive element can be added to the library and associated media added as needed without displacing the embedded base (independent of vendor) of installed media handling processes or software or equipment or requiring significant modification to these.
