A pair of controllers in a failure-tolerant storage subsystem that share a task or class of tasks when both are functioning normally, but take on the entire task or tasks when one of the components fails. Dual active controllers are connected to the same set of storage devices, and improve both I/O performance and failure tolerance compared to a single controller. Dual active controllers are also called "active-active".
