Abstract: Described herein are a system and method for remote mirroring of data and metadata from a local node to a remote node using out-of-order delivery (OOD), while also providing data integrity at the remote node. OOD may utilize increased throughput of multiple connection paths between nodes. A mirroring layer/engine executing on the local node may receive related groups of data and metadata for storing to the remote node, each related group comprising one or more data sets and one metadata set that describes and is associated with each of the one or more data sets in the related group. The mirroring layer provides data integrity at the remote node by ensuring that the metadata set of a related group is stored to the remote node only after all the data sets in the related group are stored to the remote node, thus ensuring data consistency at the remote node.

Abstract: Described herein are a system and method for remote mirroring/copying data and metadata sets from a local node to a remote node that reduces the number of metadata sets that are mirrored. In some embodiments, the local node may coalesce metadata sets into metadata chains, each metadata chain comprising a grouping of two or more metadata sets. In some instances, a “representative” metadata set of a metadata chain may be selected for sending to the remote node for storing, wherein the other metadata sets of the metadata chain are not sent to the remote node. In these embodiments, the selected metadata set may represent all the metadata sets in the chain and be the only metadata set in the chain that is transmitted and stored to the remote node. As such, the network congestion between the local and remote nodes may be reduced.
