Abstract
A method of operation of a redundant array of independent disks system includes: instantiating a first controller having a first local map and a first remote map; instantiating a second controller having a second local map and a second remote map mapped to the first local map; mapping a first memory device to the first local map by the first controller; coupling a storage device to the second controller and the first controller; and switching control of the storage device to the first controller, when a failure of the second controller is detected, by the first controller reading the first memory device.
