Abstract
A method, system and computer program product for enabling a virtual service layer to consume a storage medium at a first site and map the storage medium as one or more virtual storage volumes, enabling the virtual service layer to present the one or more virtual storage volumes for consumption at the first site, enabling a splitter of the virtual service layer to intercept I/O written to the one or more virtual storage volumes, splitting intercepted I/O to a journal based replication appliance, enabling the virtual storage volumes to be accessible at a second site, wherein the one or more the virtual storage volume are mirrored at the second site by the virtual service layer; and replicating IO from either the first site or the second site to a third site.
