Abstract: A data management system can include a set of storage media configured to implement a storage space and a set of controllers. The set of controllers can be configured to write to the storage space and to implement a set of nodes. The set of controllers can include a first controller that implements a first node and includes a first persistent memory, a second controller that implements a second node and includes a second persistent memory and a third controller that implements a third node and includes a third persistent memory. The third node can be configured to write third node journal data to the first persistent memory. The first node can be configured to generate first node journal data based on a first request received from a backend, write the first node journal data to the first persistent memory, and replicate the journal data to the second persistent memory.
