    摘要： In one aspect, a method to provide synchronous and asymmetric active-active-active access to a first storage volume using a global cache coupled to a first, second and third virtual storage volumes includes replicating asynchronously the first storage volume at a first site to a second storage volume at a second site and mirroring the first storage volume with a third storage volume at a third site. Either one of the first storage volume or the third storage volume has primary storage functionality. The method also includes virtualizing the first storage volume with the first virtual storage volume, virtualizing the second storage volume with the second virtual storage volume and virtualizing the third storage volume with the third virtual storage volume.

    摘要： In one aspect, a method includes continuously replicating a physical volume with no disruption to the replicating while inserting a virtualization layer which virtualizes the physical volume with a virtual volume and replicating the virtual volume instead of the physical volume after the inserting. In another aspect, an article includes a non-transitory machine-readable medium that stores executable instructions. The instructions cause a machine to continuously replicate a physical volume with no disruption to the replicating while inserting a virtualization layer which virtualizes the physical volume with a virtual volume and replicate the virtual volume instead of the physical volume after the inserting. In a further aspect, an apparatus includes circuitry configured to continuously replicate a physical volume with no disruption to the replicating while inserting a virtualization layer which virtualizes the physical volume with a virtual volume and replicate the virtual volume instead of the physical volume after the inserting.
