Abstract
In a software-defined data storage system with a production node and local and remote storage nodes that replicate data generated by an application running on the production node, all filesystem metadata associated with remotely replicated devices is copied from the remote storage node to memory of the production node in response to establishment of a communication link between the production node and remote storage node. That metadata is maintained in the memory for as long as the link is active and used to generate multiple remote replication IOs. Local replication is implemented by reading only necessary metadata from the local storage node on a per-IO basis. The cached metadata is flushed from memory in response to loss of the communication link.
