System and method for fault tolerant controller for network RAID

摘要

A fault-tolerant and efficient way of deducing a set of inconsistent stripes for a network RAID protocol, wherein clients forward input/output (I/O) to a particular controller device called the coordinator, which executes RAID logic and which sends out device IOs to the relevant storage devices. If the coordinator fails then a new coordinator reconstructs its state from the storage devices.
