METHODS, SYSTEMS AND COMPUTER READABLE MEDIA FOR INTELLIGENT FETCHING OF DATA STORAGE DEVICE COMMANDS FROM SUBMISSION QUEUES

摘要

Methods, systems, and computer readable media for intelligent fetching of storage device commands from submission queues are disclosed. On method is implemented in a data storage device including a controller and a memory. The method includes collecting submission queue command statistics; monitoring resource state of the data storage device. The method further includes using the submission queue command statistics and the resource state to select a submission queue from which a next data storage device command should be fetched. The method further includes fetching the command from the selected submission queue. The method further includes providing the command to command processing logic.
