Abstract
A data relay device including: a storage circuit that stores, for each of storages, an upper limit number indicating a number of input/output (I/O) commands that are transmittable; a relay circuit that relays data transmitted and received between one or more control devices and the storages; and a control circuit that performs: counting, for each storage, a number of commands indicating a number of the I/O commands that have been transmitted via the relay circuit and for which no response has been returned from transmission destination storages among the storages; in response to a request to retry transmission of the I/O commands from one storage among the storages, registering a first number in the storage circuit as the upper limit number of commands that corresponds to the one storage, the first number being a number obtained by subtracting one from a counted value of the number of commands.
