CloudTier Transparent Storage Tiering SDK について

コストの高いストレージメディアとコストの低いストレージメディア間で自動的にデータを移動

CloudTier Transparent Storage Tiering SDK allows file system tiered storage which is a data storage technique which automatically moves data between high-cost and low-cost storage media. A stub is created for and replaces each migrated file on the fast disk drives. On the local system, a stub file looks and acts like a regular file. When you or a Windows application accesses a migrated file stub, the driver will retrieve the full file from the repository to which it was migrated.

CloudTier Transparent Storage Tiering SDK (formally EaseFilter File System Filter Driver SDK)

A file system filter driver intercepts requests targeted at a file system or another file system filter driver. By intercepting the request before it reaches its intended target, the filter driver can extend or replace functionality provided by the original target of the request.To develop file systems and file system filter drivers, use the Windows Driver Kit (WDK),which is provided by Microsoft. Even with the resources available in the Windows Driver Kit (WDK) developing file systems is certainly a challenge. To simplify your development and to provide you with a robust and well-tested file system filter driver that works with all versions and patch releases of the Windows operating systems supported by Microsoft, EaseFilter Inc. offers the file system filter driver SDK which provides a complete, modular environment for building active file system filters in your application.

CloudTier Transparent Storage Tiering SDK

File system tiered storage 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 optical discs and magnetic tape drives. 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 on the fast disk drives. On the local system, a stub file looks and acts 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. The EaseTag Tiered driver retrieves the full file from the repository to which it was migrated.
