Automatic movement of files from hard disk to slower, less-expensive storage media; often including backup.
Software management tools that identify and manage access to stored data. On-line storage (magnetic / optical devices) used for rapid retrieval of data. Near-line storage (eg. Jukeboxes) permit access to data within 1-20 seconds but without the need for operator intervention. Off-line storage (eg. Tapes) generally require operator intervention before the data can be made available.
(n.) hierarchical storage management.
hierarchical storage management. A technology that automates storage management and lowers storage costs by automatically migrating infrequently accessed files from local storage to remote storage and recalling the files upon user demand.
Hierarchical Storage Management. The automated migration of data objects among storage devices, usually based on inactivity. Abbreviated HSM. Hierarchical storage management is based on the concept of a cost-performance storage hierarchy. By accepting lower access performance (higher access times), one can store objects less expensively. By automatically moving less frequently accessed objects to lower levels in the hierarchy, higher cost storage is freed for more active objects, and a better overall cost: performance ratio is achieved.

Hierarchical Storage Management. A software and hardware system that automatically moves files from hard disks to slower, less expensive storage media (optical and tape).
Host Security Module (or Hardware Security Module) - a hardware device used for storing keys and performing cryptographic functions under control of a host computer
Hierarchical Storage Management. A storage system in which new, frequently used data is stored on the fastest, most accessible (and generally more expensive) media (e.g., RAID) and older, less frequently used data is stored on slower (less expensive) media (e.g., tape).
A storage management technology that can be used to identify inactive data and move it to near-line storage, automate the retrieval process, and migrate the data back to the primary storage medium and provide access for the user.
Hierarchical Storage Management. Software that automatically migrates files from on-line to near-line storage media, usually on the basis of the age or frequency of use of the files.
hierarchical storage management. In AS/400 storage management, an automatic method to manage and distribute data between the different storage layers. The storage layers can include high-performance disk units, compressed disk units, and tape library devices.
See hierarchical storage management (HSM).
Hierarchical Storage Manager. Software aiming at managing mass storage data in order to let very active data reside on hard disk, and to migrate less active data from/to less expensive storage such as tape units.
Hierarchical Storage Management. The process of automatically storing data on the lowest-cost devices that can support the performance required by the applications. To users, data storage never fills; file access, regardless of location in the storage hierarchy, is completely transparent. The software automatically manages multiple levels of storage hierarchy.
Hardware Security Module. The system within a smart card infrastructure that securely manages the encryption and transmission of data.
Hierarchical Storage Management, running as a mass storage system under ADSM.
Hierarchical Storage Management. A data storage system that automatically moves data between high-cost and low-cost media, based on parameters the administrator sets.
Heirarchical Storage Management. Storage technologies have different characteristics in terms of access speed, density and cost. So it's not economic to use just one type of storage for all data needs. Luckily some data is needed more frequently than other data, so it's possible to manage the data which is stored in a heirarchy which matches the organization's applications and economics, and moves data up or down from RAM, local disk, network attached RAID, optical jukebox, tape library, web storage etc as needed. Backup software & HSM
(hierarchical storage management) a system of ranking and storing information across a variety of device types
systems move files from magnetic disk to optical disk to tape. The idea is to go from fast but relatively expensive storage to slower more economical storage as the need for the files diminishes. ... more
The management of file backup and archiving in a way that uses storage devices economically and without the user needing to be aware of when files are being retrieved from backup storage media. Although HSM can be implemented on a standalone system, it is more frequently used in the distributed network of an enterprise. The hierarchy represents different types of storage media, such as redundant array of independent disks systems, optical storage, or tape, each type representing a different level of cost and speed of retrieval when access is needed.
