摘要
A storage system in one embodiment comprises a storage controller and a plurality of storage devices comprising a plurality of memory portions. The storage controller is configured to monitor a plurality of servers for a failure event. The servers store a plurality of copies of the memory portions. The storage controller is further configured to mark as invalid a copy of a memory portion on a failed server, search for and identify a location on an operational server for storing a new version of the copy, and communicate the copy invalidity and the identified location to a client device using the memory portion. The client device is configured to generate the new version of the copy for storage on the operational server, and the storage controller receives a notification from the client device regarding whether the new version of the copy was generated and stored on the operational server.
