A storage system includes a host, a back plane including a switching block and connected to the host, a plurality of storage sets connected to the back plane to receive power from the host, and a battery module connected to the back plane to supply spare power to at least one storage set of the plurality of storage sets through the switching block, when an abnormal power drop is detected in the at least one storage set of the plurality of storage sets. The battery module controls the at least one storage set to perform a data flushing operation, when power less than or equal to a threshold value is detected in the at least one storage set after supplying the spare power.

Storage system including battery module and method for operating the same

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

A solid-state drive device includes a first module including a first region containing a volatile main memory device and a controller device and a second region containing a first nonvolatile memory device, a second module disposed on the first module and having a third region containing a second nonvolatile memory device, the second module being connected to the first module, and a heat dissipating member disposed on the second module as vertically juxtaposed with the first and second modules. The heat dissipating member has a protruding portion protruding toward the first module and in direct thermal contact with the first region, and a plate-shaped portion having a main surface in direct thermal contact with the third region.

Solid state drive device and computer server system including the same

A hard disk drive includes a base, an actuator arm pivotably installed on the base, and a latch device to latch the actuator arm at a parking position. The latch device includes a latch stop that protrudes from a side wall of the base and has an inclined surface, and a latch lever pivotably installed on the base and contacts and slides along the inclined surface of the latch stop during the rotation in an unlatching direction.
