Electronic device supporting out-of-band communication, and method of operating the same

A method of operating an electronic device including a host device including a processor and a baseboard management controller (BMC), a first storage device including a first storage controller and a first micro controller unit (MCU), and a second storage device including a second storage controller and a second MCU, the method comprising:

• providing, by the BMC, a first request comprising information corresponding to first environment data to the first MCU through an out-of-band communication;
• providing, by the first MCU, a first response corresponding to the first request to the BMC through the out-of-band communication;
• providing, by the BMC, a second request comprising information corresponding to second environment data to the second MCU through the out-of-band communication;
• and
• providing, by the second MCU, a second response corresponding to the second request to the BMC through the out-of-band communication,
• wherein the processor communicates with the first and the second storage controllers through an in-band communication different from the out-of-band communication.

An electronic device comprising:

• a host device comprising a processor and a baseboard management controller (BMC);
• and
• a storage device comprising a storage controller and a micro controller unit (MCU),
• wherein the BMC is configured to provide a request comprising information corresponding to environment data to the MCU through an out-of-band communication,
• wherein the MCU is configured to provide a response corresponding to the request to the BMC through the out-of-band communication, and
• wherein the processor and the storage controller communicate with each other through an in-band communication different from the out-of-band communication.
