Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A matching key search method of a server system including a storage device, the storage device including a nonvolatile memory device and a buffer memory. The matching key search method includes receiving a search command for a keyword from a host, reading data from a memory area of the memory device corresponding to an address included in the search command and storing the read data in the buffer memory, determining whether the read data matches the keyword, transmitting a result of the determining to the host without transmitting the read data to the host, and generating a matching key table with reference to the result of the determining and storing the generated matching key table in the buffer memory.
