Data relay device, storage device, and response delay monitoring method

摘要

A data relay device relays a read request from a source device to a destination device and relays data corresponding to the read request from the destination device to the source device. The data relay device monitors elapsed time from a time point at which a read request is relayed to the destination device. When the elapsed time reaches warning time or error time, the data relay device sends a warning message or an error message to the source device.
