Abstract
An autonomous RAID data storage device locking system includes first RAID data storage device(s) that store data included in a data stripe, and that are coupled to a second RAID data storage device. The second RAID data storage device receives a command to perform a data update operation on a subset of data included in the data stripe, and transmits a locking request to each first RAID data storage device. When the second RAID data storage device receives a locking confirmation that indicates that each first RAID data storage device is locked, it completes the data update operation on the subset of data included in the data stripe. The second RAID data storage device then transmits an unlocking request to each first RAID data storage device to cause them to unlock, and transmits a completion communication that indicates that the data update operation has been performed.
