US 2022/0035564 A1 · SYSTEMS AND METHODS FOR PROCESSING COMMANDS FOR STORAGE DEVICES

Abstract

Methods and systems for processing a command from a host to a storage device are disclosed. A first controller of the storage device receives a first command from the host via a first queue. The first queue is exposed to the host. The storage device generates a second command based on the first command, and submits the second command to a second controller of the storage device via a second queue. The second command and the second queue are unexposed to the host. The second controller obtains and processes the second command from the second queue, where the processing is for accessing non-volatile storage media of the storage device. Based on status of the second command, the first controller transmits a signal to the host for indicating completion of the first command.

Dependent claims

A method for processing a command from a host to a storage device, the method comprising:

receiving, by a first controller of the storage device, a first command from the host via a first queue, wherein the first queue is exposed to the host;
generating, by the storage device, a second command based on the first command;
submitting, by the storage device, the second command to a second controller of the storage device via a second queue, wherein the second command and the second queue are unexposed to the host;
obtaining and processing, by the second controller, the second command from the second queue, wherein the processing is for accessing non-volatile storage media of the storage device;
and
based on status of the second command, transmitting, by the first controller, a signal to the host for indicating completion of the first command.
