US Patent 12130772 Multi-processor device with external interface failover

A multi-processor device is disclosed. The multi-processor device includes interface circuitry to receive requests from at least one host device. A primary processor is coupled to the interface circuitry to process the requests in the absence of a failure event associated with the primary processor. A secondary processor processes operations on behalf of the primary processor and selectively receives the requests from the interface circuitry based on detection of the failure event associated with the primary processor.
