A data migration system supports a low-latency and reduced overhead data storage protocol for data storage sharing in a non-collision fashion which does not require inter-communication and permanent arbitration between data storage controllers to decide on the data placement / routing. The multiple data fragments of data sets are prevented from routing to the same storage devices by a multi-step selection protocol which selects (in a first phase of the selection routine) a healthy highest ranked drive enclosure, and further selects (in a second phase of the selection routine) a healthy highest-ranked data storage controller residing in the selected drive enclosure, for routing data fragments to different storage pools assigned to the selected data storage devices for exclusive “writing” and data modification. The selection protocol also contemplates various failure scenarios in a data placement collision free manner.
