PARALLEL ASYNCHRONOUS DATA REPLICATION

摘要

A primary data storage system and a secondary data storage system are connected with a mesh of network connections during replication procedures from the primary storage system to the secondary storage system. In some implementations, at the primary storage system, file system metadata is analyzed for different subsets of the primary file system to determine changed and/or potentially changed files and/or directories for each subset. Change information is communicated from the primary storage system for a plurality of the subsets to a secondary storage system in parallel to a plurality of network addresses assigned to network ports of the secondary storage system.

1. A method of replicating data from a primary storage system to a secondary storage system comprising:
at the primary storage system, analyze file system metadata for different subsets of the primary file system to determine changed and/or potentially changed files and/or directories for each subset; communicate change information from the primary storage system for a plurality of the subsets to a secondary storage system in parallel to a plurality of network addresses assigned to network ports of the secondary storage system.
