Abstract
A method and system enables data redundancy across servers, networks, and controllers by using standard redundant files as underlying storage for RAID subsystem configurations. A redundant array of independent disk (RAID) subsystem includes a front-end interface configured to process non-redundant requests received from a primary file system communicating with an application program. A back-end interface of the RAID subsystem is configured to process redundant requests corresponding to the non-redundant requests. The redundant requests to be issued to a secondary file system communicates with a block mode device including multiple physical storage devices.
