Abstract: According to one embodiment, a storage system includes a network interface controller, a volatile memory and a storage device. The network interface controller is configured to communicate with a client using remote direct memory access. The network interface controller is configured to store write data and a submission queue entry including a write request of the write data transferred using the remote direct memory access in the volatile memory. The storage device is configured to write, when the submission queue entry is stored in a submission queue of the volatile memory, the write data to the storage device based on the submission queue entry.

Abstract: A storage system is provided, including: a host including a memory, the memory including a submission queue and a completion queue and being configured to store update frequency information; and a memory system configured to be connectable with the host and including a nonvolatile memory and a controller, the controller configured to control the nonvolatile memory, to receive the update frequency information of the submission queue from the host, to read command information stored in the submission queue based on the received update frequency information, and to execute controlling for the nonvolatile memory based on the command information.

Abstract: A storage system includes: a storage device including a memory and a memory controller; a first device coupled to the storage device; and a control part. The control part is configured to: store, in a first storing device, a first order that orders the storage device to read first data from the memory; and store a second order in a second storing device. The second order orders the first device to transmit a first request to the storage device. The first request requests the first data to be transferred to the first device. The first device is configured to start processing the second order before completion of the reading of the first data from the memory.

Abstract: A storage system is provided, including: a host including a memory, the memory including a submission queue and a completion queue and being configured to store update frequency information; and a memory system configured to be connectable with the host and including a nonvolatile memory and a controller, the controller configured to control the nonvolatile memory, to receive the update frequency information of the submission queue from the host, to read command information stored in the submission queue based on the received update frequency information, and to execute controlling for the nonvolatile memory based on the command information.

Abstract: According to one embodiment, a memory system includes a nonvolatile memory, and a controller configured to be connectable with a host and control the nonvolatile memory. The controller is configured to receive update frequency information of a submission queue from the host, read command information stored in the submission queue in accordance with the update frequency information, and execute controlling for the nonvolatile memory based on the command information.
