Method and system for data migration in a distributed RAID implementation

摘要

Embodiments of the systems and methods disclosed provide a distributed RAID system comprising a set of data banks. More particularly, in certain embodiments of a distributed RAID system each data bank has a set of associated storage media and executes a similar distributed RAID application. The distributed RAID applications on each of the data banks coordinate among themselves to distribute and control data flow associated with implementing a level of RAID in conjunction with a volume stored on the associated storage media of the data banks. Migration of this volume, or a portion thereof, from one configuration to another configuration may be accomplished such that the volume, or the portion thereof, and corresponding redundancy data may be stored according to this second configuration.
