Abstract
One example method includes receiving an IO request from an application, determining if an affinity policy applies to the application that transmitted the IO request, when an affinity policy applies to the application, directing the IO request to a specified site of a replication system, when no affinity policy applies to the application, determining if a lag in replication of the IO request from a primary site to a replication site is acceptable, if a lag in replication of the IO request is acceptable, processing the IO request using performance based parameters and/or load balancing parameters, and if a lag in replication of the IO request is not acceptable, either directing the IO request to a most up to date replica site, or requesting a clone copy of a volume to which the IO request was initially directed and directing the IO request to the cloned copy.
