active/active array

Part of the Storage hardware glossary:

Active/active (also called dual active) is a storage array configuration in which two (or more) storage controllers work together to process inputs/outputs (I/Os). Active/active can be contrasted with active/passive, an array configuration in which the first controller processes all I/O requests and the second controller is only used in the event of a  failover.
