Abstract
A new approach is proposed that contemplates systems and methods to support extensible/flexible storage access in real time by virtualizing a plurality of remote storage devices as NVMe namespace(s) via an NVMe controller using a storage network protocol. The NVMe controller exports and presents the remote storage devices to one or more VMs running on a host attached to the NVMe controller as the NVMe namespace(s), wherein these remote storage devices appear virtually as one or more logical volumes of a collection of logical blocks in the NVMe namespace(s) to the VMs. As a result, each of the VMs running on the host can access these remote storage devices to perform read/write operations as if they were local storage devices via the NVMe namespace(s).
