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 storage device includes a nonvolatile memory device, and a storage controller configured to control the nonvolatile memory device. The storage controller includes: (i) a quality of experience (QoE) manager configured to schedule a request received from an external user equipment, based on storage device information and network information, and (ii) a software-defined networking (SDN) manager configured to set a network transfer path to the external user equipment, which is associated with video data corresponding to the request.

Storage devices, methods of operating storage devices, and streaming systems including storage devices

The present disclosure provides methods and apparatuses for data loss prevention of a storage device. In some embodiments, the data loss preventing method includes receiving, from a host system, a query plan corresponding to necessary data to be stored in a volatile memory. The data loss preventing method further includes generating, based on the query plan, a data priority list corresponding to the necessary data. The data loss preventing method further includes selecting, based on the data priority list, at least one portion of the volatile memory, when a main power supplied by the host system drops to or below a power level threshold. The data loss preventing method further includes moving the necessary data to the at least one portion of the volatile memory.

Storage device preventing loss of data in situation of lacking power and operating method thereof

A computational storage device includes a control module, and a nonvolatile memory connected to the control module. The nonvolatile memory is configured to store a plurality of graph data elements, which comprises a plurality of nodes and a plurality of edges that connect at least a portion of the plurality of nodes to each other, in a first memory area and a second memory area each having a plurality of blocks and having different read speeds. The control module is configured to store a first graph data element of the plurality of graph data elements having a relatively high degree of association with one node of the plurality of nodes in the first memory area, and store a second graph data element of the plurality of graph data elements having a relatively low degree of association with the one node of the plurality of nodes in the second memory area.
