System and method of orchestrating execution of commands in a non-volatile memory express (NVMe) device

A system for orchestrating execution of commands in a nonvolatile memory express (NVMe) device, the system comprising:

• a host device;
• and
• the NVMe device connected to the host device, wherein the NVMe device:
• receives the commands in a submission queue and from the host device,
• identifies, among the commands, a configuration command for changing a state or an attribute of the NVMe device, and
• initiates, in response to identifying the configuration command, selective command fencing that orchestrates the execution of the commands in the NVMe device, wherein
• for each of a plurality of first commands among the commands, the selective command fencing comprises determining whether the first command is to be executed before or after execution of the configuration command based upon whether first command operates with an attribute that the configuration command will alter.

A method executed by a nonvolatile memory express (NVMe) device, the method comprising:

• receiving, from one or more external hosts, a plurality of commands to be executed by a multi-core processor of the NVMe device in parallel;
• identifying, among the commands, a first set of commands that are all directed toward a same attribute of the NVMe device;
• identifying a first command, among the first set of commands, whose execution affects an execution outcome of another command within the first set;
• submitting the first command to a parallel-processing execution pipeline for execution by the NVMe device in response to determining that a state of the attribute is idle;
• and
• deferring, until after the first command is executed, execution of each command within the first set whose execution is affected by the execution of the first command.
