Provided is a server device which may be stably operated in spite of power loss and a method of operating the same. The server device according to an embodiment of the present invention includes: a host system; a plurality of memory modules; a backplane configured to transmit main power supplied from the host system to the plurality of memory modules; and at least one replaceable battery module connected to the backplane and configured to supply first auxiliary power to the plurality of memory modules, wherein the plurality of memory modules includes a volatile memory, a non-volatile memory; and a memory module controller using the first auxiliary power supplied from the at least one replaceable battery module to maintain data of the volatile memory or flush data of the volatile memory to the non-volatile memory, in response to the power loss occurring in the main power.

Server device capable of being stably operated in spite of power loss and method of operating the same

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.

A solid state drive apparatus includes a casing including a top plate, a bottom plate, a first sidewall, and a second sidewall. A first substrate is disposed inside the casing. At least one first semiconductor chip is mounted on the first substrate. A second substrate is disposed inside the casing. At least one second semiconductor chip is mounted on the second substrate. A heat dissipation structure is disposed between the first substrate and the second substrate and includes a lower heat dissipation panel contacting the at least one first semiconductor chip. An upper heat dissipation panel contacts the at least one second semiconductor chip. An air passage is provided between the lower heat dissipation panel and the upper heat dissipation panel and extends from the first sidewall of the casing to the second sidewall.

Solid state drive apparatus and data storage apparatus including the same

A solid state drive (SSD) apparatus includes a case including an air tunnel disposed between an inner plate and an upper wall and an accommodation space between the inner plate and a lower wall. The air tunnel extends in a first direction, and both end parts of the air tunnel are exposed to the outside. A substrate is disposed in the accommodation space. At least one semiconductor chip is disposed on the substrate.

An embodiment of the present disclosure may provide a power consumption controlling method and apparatus. An embodiment of the present disclosure may provide a method and apparatus for controlling power consumption by a base station, the method including determining empty symbol duration in at least one subframe; and performing a power amplifier (PA) on/off operation based on the determination result. Further, an embodiment of the present disclosure may provide a method and apparatus for controlling power consumption by a base station, the method including generating baseband in-phase/quadrature-phase (IQ) data; determining whether the baseband IQ data includes data which must be transmitted for a predetermined time; and controlling a PA on/off based on the determination result and a transient of the PA.
