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.

Redundant array of independent disks system with inter-controller communication and method of operation thereof

A method of operation of a storage controller system includes: accessing a first controller having a synchronization bus; accessing a second controller, by the first controller, through the synchronization bus; and receiving a first transaction layer packet by the first controller including performing a multi-cast transmission between the first controller and the second controller through the synchronization bus.
