Abstract:
In one aspect, a method includes forming a virtualized grid consistency group to replicate logical units, running a first grid copy on a first data protection appliance (DPA), running a second grid copy on a second DPA, splitting to the first DPA IOs intended for a first subset of the logical units and splitting to the second DPA IOs intended for a second subset of the logical units different from the first subset of logical units.
