Publisher description for EaseTag Tiered Storage Filter Driver SDK
File System Tiered Storage (hierarchical storage management, HSM) Filter Driver SDK, is a data storage technique which automatically moves data between high-cost and low-cost storage media. Tiered Storage Filter systems exist because high-speed storage devices, such as hard disk drive arrays, are more expensive (per byte stored) than slower devices, such as network attached storage(NAS),optical discs and magnetic tape drives. Tiered storage file system filter driver normally integrates with storage lifecycle management(SLM) software, or called information lifecycle management (ILM) software. Tiered Storage Filter systems store the bulk of the enterprise's data on slower devices. A stub is created for and replaces each migrated file in the fast disk drives. On the local system, a stub file looks and act like a regular file. When you or a Windows application accesses a migrated file stub, the Windows operating system transparently directs a file access request to the Tiered Storage Filter driver. This driver retrieves the full file from the repository to which it was migrated. The automated tiered storage can integrate with existing applications, without affecting the original data and programs. Without any modification of existing applications, the local storage can automatically be extended to the network storage. Tiered storage can be widely used in telecommunications, government, oil, medical and other industries. Tiered storage is the first choice of medical PACS (PictureArchivingandCommunicationSystem, medical imaging storage and Transmission systems), a lot of data in such applications are rarely visit, these data are transferred to a less expensive network storage. When users and applications access the stub files in the local storage, it is completely transparent, the system will automatically restore the data back to the stub file from the network storage server.
