A hardware-based mirroring agent (1602) that provides a LUN-based I/O interface to remote host computers (1606), including mirrored LUNs, implemented via remote data storage devices (1608, 1610). The hardware-based mirroring agent is similar to a disk array, but manages and provides to host computers an interface to remote data storage devices, rather than to internal data storage devices, as in the cas e of disk arrays.
