Abstract
An exemplary embodiment disclosed herein is a method including a virtual storage controller receiving an input/output (I/O) command using a native drive communications protocol from a software application on a user virtual machine running on the host machine; determining whether a local service virtual machine is unresponsive to the virtual storage controller; translating the I/O command from the native drive communications protocol to an IP-based storage communications protocol to create a translated I/O command, in response to the local service virtual machine being unresponsive to the virtual storage controller; sending the translated I/O command to a remote service virtual machine, wherein the remote service virtual machine is configured to send the translated I/O command to a local storage and receive a response from the local storage; and receiving the response from the remote service virtual machine.
