US Patent:

6366988, Apr 2, 2002

Filed:

Jul 17, 1998

Appl. No.:

09/118218

Inventors:

Mark Skiba - Marina del Rey CA
Mikhail Ryzhkin - Las Vegas NV

Assignee:

Storactive, Inc. - Marina Del Rey CA

International Classification:

G06F 1200

US Classification:

711165, 711100, 711170, 711202, 707203

Abstract:

Systems and methods for improved electronic data storage management that allow the file system to physically adapt and optimize to a variety of add-on hardware components (such as hard disks, removable drives, CD ROM drives, etc. ) while virtually maintaining a stable system configuration from an application software point of view. The Redirector presents a virtual view of the file system by providing a virtual view of logical volumes. Through the use of a Redirector component, all application program file APIs to the operating system are filtered; if the file, or directory is redirected, then the call is sent in a modified form to the operating system to its redirected physical location. The physical movement of files is accomplished through the use of a Migrator component. The Migrator makes a copy of the file, verifies the correctness of the copy, updates the redirector table, and then removes the physical file from its original location.
