Network storage device storing large amount of data

A network storage device connected with a network fabric, the network storage device comprising:

• a buffer memory configured as a data buffer for exchanging data between the network storage device and the network fabric;
• a network storage controller configured to perform interfacing with the network fabric, and to translate and process a command provided through the network fabric, and implemented with a single chip;
• and
• a nonvolatile memory cluster configured to exchange data with the network storage controller under control of the network storage controller,
• wherein the network storage controller includes a storage controller configured to be connected with the network fabric through a first port, to exchange data with the buffer memory through a second port, and to be connected with the nonvolatile memory cluster through a third port, wherein the third port includes a plurality of channels,
• wherein the nonvolatile memory cluster comprises
• a first nonvolatile memory array directly connected with the network storage controller through a first channel of the plurality of channels,
• a nonvolatile memory switch connected with the network storage controller through a second channel of the plurality of channels, and
• a second nonvolatile memory array configured to communicate with the network storage controller under control of the nonvolatile memory switch, and
• wherein the network storage controller is configured to translate a first command provided from the network fabric as the command into a second command for controlling the nonvolatile memory cluster, and supports a network transmission format comprising a high-speed Ethernet system, and
• wherein the network storage controller processes the network transmission format for supporting an Ethernet protocol, an NVMe-oF protocol, and an NVMe protocol at a single layer.
