Abstract: An autonomous RAID data storage system includes a RAID storage controller device that communicates with RAID data storage devices in order to configure them to perform direct command operations with each other. A first RAID data storage device receives a multi-step command from the RAID storage controller device and performs a first subset of operations associated with the multi-step command, while also performing direct command operations with a second RAID data storage device in order to cause it to perform a second subset of operations associated with the multi-step command, When the first RAID data storage device completes the first subset of operations and receives a first completion communication from the second RAID data storage device that indicates that the second subset of operations are completed, it sends a second completion communication to the RAID storage controller device that indicates that the multi-step command is completed.
