Provided is a storage device including a non-volatile memory, a memory controller configured to communicate with a host device through a first channel and configured to control the non-volatile memory, and a sub controller configured to communicate with the host device through a second channel and configured to monitor an operation status of the memory controller. The sub controller is configured to perform operations including broadcasting state information of the storage device including the operation status to at least one external device through the second channel, and performing a recovery operation on the memory controller when recovery information is received from the at least one external device through the second channel.

Storage device and storage system

An electronic device includes a host device and a plurality of storage devices. The host device includes a processor and a baseboard management controller (BMC). Each of the plurality of storage devices includes a storage controller and a micro controller unit (MCU). The processor and the storage controller support in-band communication, and the BMC and the MCU support out-of-band communication. The BMC receives monitoring data from the MCU of each of the plurality of storage devices based on the out-of-band communication. The processor allocates a first workload among one or more workloads to a first storage device among the plurality of storage devices, based on a monitoring data set including the monitoring data. The first storage device executes the first workload based on the in-band communication.

Electronic device and operating method thereof

Disclosed is a method of operating an electronic device which includes a host device and a storage device. The host device includes a processor and a baseboard management controller (BMC), the storage device includes a storage controller and a micro controller unit (MCU), and the BMC and the MCU support out-of-band communication. The method of operating the electronic device includes providing, by the BMC, a first request including information about environment data to the MCU through the out-of-band communication, and providing, by the MCU, a first response corresponding to the first request to the BMC through the out-of-band communication.

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

The present invention, with respect to an electronic device, discloses an electronic device including: a communication unit that transmits a signal requesting a call to another electronic device and receives screen display information from the another electronic device; and a processor that controls so as to display a user interface based on the screen display information on a call connection screen. The present invention is not limited to the above embodiment, however, and other embodiments are possible.
