Abstract: A network storage device connected with a network fabric includes a network storage controller that performs interfacing with the network fabric and translates and processes a command provided through the network fabric, and a nonvolatile memory cluster that exchanges data with the network storage controller under control of the network storage controller. The nonvolatile memory cluster includes a first nonvolatile memory array connected with the network storage controller through a first channel, a nonvolatile memory switch connected with the network storage controller through a second channel, and a second nonvolatile memory array communicating with the network storage controller under control of the nonvolatile memory switch.

Abstract: In a method of scheduling jobs in a storage device, a first job is performed. While the first job is being performed, a first timestamp for the first job is pre-updated based on a pre-defined operation time table that represents a relationship between operations of the storage device and operation times. While the first job is being performed, scheduling requests are received that are associated with a second job to be performed after the first job. While the first job is being performed, a scheduling operation for selecting the second job is pre-performed based on the scheduling requests and the timestamps.

Abstract: A storage device includes a nonvolatile memory and a controller. The controller includes a job manager circuit and a processor. The job manager circuit manages a first-type job associated with the nonvolatile memory, and the processor processes a second-type job associated with the nonvolatile memory. The job manager circuit manages the first-type job without intervention of the processor. The processor provides a management command to the job manager circuit in response to a notification received from the job manager circuit, such that the second-type job is processed.
