FLOW CONTROL IN REMOTE REPLICATION

摘要

A method for controlling multiple replication processes that includes allocating, by a local storage system and for each replication process, local resources for performing local operations that comprise transmitting remote replication content to a remote storage system; the allocating is responsive to a state of transmission of the replication content and a maximal local storage system allocation threshold; allocating, by the remote storage system and for each replication process, remote resources for performing remote operations that comprise handling the replication content transmitted from the local storage system; the allocating is responsive to a load associated with the handling of the replication content, and a maximal remote storage system allocation threshold; and executing each replication process by the replication process local and remote storage systems resources.

1. A method for controlling multiple replication processes, the method comprises:
allocating, by a local storage system and for each replication process of the multiple replication processes, local resources for performing local operations related to the replication process, wherein the local operations comprise transmitting replication content to a remote storage system; wherein the allocating of the local resources is responsive to (a) a state of transmission of the replication content, and (b) a maximal local storage system allocation threshold; allocating, by the remote storage system and for each replication process of the multiple replication processes, remote resources for performing remote operations related to the replication process, wherein the remote operations comprise handling the replication content transmitted from the local storage system; wherein the allocating of the remote resources is responsive to a load associated with the handling of the replication content, and (b) a maximal remote storage system allocation threshold; executing, for each replication process of the multiple replication processes, the local operations in response to the allocation of the local resources; and executing, for each replication process of the multiple replication processes, the remote operations in response to the allocation of the remote resources.
