Abstract:
In one aspect, a method to provide asymmetric active-active access to a first storage volume using a global cache coupled to a first and second virtual storage volumes includes replicating asynchronously the first storage volume at a first site to a second storage volume at a second site, virtualizing the first storage volume with the first virtual storage volume; and virtualizing the second storage volume with the second virtual storage volume. The first storage volume has primary storage functionality.
