From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

The SNIA common RAID disk data format (DDF) defines a standard data structure describing how data is formatted across disks in a RAID group. The DDF structure allows a basic level of interoperability between different suppliers of RAID technology. The common RAID DDF structure benefits storage users by enabling in-place data migration or recovery after controller failure using systems from different vendors.[1]

DDF is an external metadata format that is compatible with the mdraid subsystem in the Linux kernel. The mdadm command-line utility is a part of the mdraid subsystem.[2]
