ASYNCHRONOUS REPLICATION OF SYNCHRONOUSLY REPLICATED DATA

Abstract:

A storage system asynchronously replicating a synchronously replicated dataset, where the asynchronous replication of the asynchronously replicated dataset includes: determining, at a target storage system, multiple work items corresponding to a dataset stored among multiple source storage systems, wherein each respective work item corresponds to a respective subset of the dataset; and for each session from among a plurality of sessions operating on the target storage system: determining one or more computing environment factors affecting performance of replication of data from one or more of the multiple source storage systems to the target storage system; identifying, for a given session and based on the one or more computing environment factors, a respective source storage system and a quantity of work items; and replicating, from the respective storage system, one or more subsets of data corresponding to the quantity of work items.
