Abstract
A device for detecting zone parallelity includes a detection control circuit configured to generate respective first and second requests for first and second zones among a plurality of zones included in a solid state drive (SSD). An SSD controller is configured to control the SSD by generating a first command and a second command corresponding to the first request and the second request, respectively, and to schedule the first command and the second command. The detection control circuit determines zone parallelity of the first and second zones using response characteristics of the responses of the SSD to the first request and the second request. The response characteristics may include a latency of a response.
Claims10
A device for detecting zone parallelity, the device comprising:
- a detection control circuit configured to generate a first request and a second request for two zones among a plurality of zones included in a solid state drive (SSD);
- and
- an SSD controller configured to control the SSD by generating a first command and a second command corresponding to the first request and the second request, respectively,
- wherein the SSD controller schedules the first command and the second command, and
- wherein the detection control circuit determines zone parallelity of the two zones using response characteristics of the SSD for the first request and the second request.
A method for detecting zone parallelity of two zones, the method comprising:
- selecting the two zones from among a plurality of zones of a solid state drive (SSD);
- providing commands for the two zones to an SSD;
- measuring response characteristics of the SSD after providing the commands for the two zones to the SSD;
- and
- determining the zone parallelity of the two zones based on the response characteristics.
