Apparatus and method for accessing a non-volatile memory blade using multiple controllers in a non-volatile memory based storage device

Abstract

Various systems, methods, apparatuses, and computer-readable media, for accessing a storage device are described. In certain example embodiments, an active/active fault tolerant storage device comprising two or more controllers may be implemented. In one embodiment, each controller may be coupled to the non-volatile memory’ (NVM) blades comprising the non-volatile memory (NVM) storage medium. In one example implementation, a standardized protocol, such as Peripheral Component Interconnect Express protocol may be used for communicating amongst the various components of the controller and also the NVM storage medium.
