Abstract
A data management system can include a disk unit and a set of controllers. The disk unit can contain, at least in part, a set of storage media, a first persistent memory, and a second persistent memory. The set of storage media can be configured to implement a storage space. The set of controllers can be configured to write to the storage space and to implement a set of nodes including a first node and a second node. The first node can be configured to generate and write first node journal data to the first persistent memory. The second node can be configured to obtain a failure indication for the first node, obtain the first node journal data from the second persistent memory, and generate and provide a reply to a backend using the first node journal data.
