Data recovery bypassing protocol for cloud network storage system

Abstract

Methods and systems implement a data recovery bypassing protocol, by which a storage node of a cloud network may return a replica of lost data being recovered to timely service a read operation call from a computing node of the cloud network, without waiting for completion of a first, a second, and a third recovery function. Storage devices implement asynchronous event reporting ('AER') protocol between a storage engine and storage devices of the storage node. Within a storage device, an AER generation protocol enables a storage controller and a flash memory cell array of the storage device to intercommunicate, and enables the storage controller to generate AER messages. By bypassing secondary recovery, the computing node may successfully read lost data from many or all storage nodes of the cloud network, thus completing read operation calls without suffering milliseconds in performance loss and blocking, averting observable degradation of QoS of the overall computing system.
