An active/active remote mirroring system, for example an active/active SRDF system, provides for remote mirroring between multiple storage volumes, e.g., a first storage device and a second storage device, in which the storage devices may both be active. A plurality of hosts may be coupled to either the first storage device, the second storage device, or both to conduct read and write operations from and to the storage devices, for example to nearest device. The hosts may be part of an application cluster. The first storage device and the second storage device may be connected via a link, such as an SRDF link, for providing remote mirroring capabilities between the storage volumes. In various embodiments the first and second storage devices may be separate devices, volumes, or portions thereof, and/or may be different portions of the same storage device.
