The abort command includes a slot of the target command to be aborted. Thereafter, the method includes placing the abort command into an Admin queue of the NVMe SSD and executing the abort command using the slot of the target command to be aborted by updating an I/O completion queue of the host with the target command to be aborted. The method further includes updating a head doorbell of the doorbell registers of the NVMe SSD and updating the abort command in an Admin completion queue of the host.
