NVMe Queue Pause-Resume Test (LOGO)
This test verifies the device’s capability of handling I/s in the event of pausing and resuming Submission Queue, Completion Queue, or both.
The test monitors for any reset events that may happen as a result of IOs timing out.
The maximum pause-resume of I/O is currently set to a low value of 4 seconds.
Time period of Pause-Resume of Queues could be uniform or random
Interval Time period between Pause-Resume of Queues could be uniform or random
Queue Depth chosen for IO scenarios could max out at value specified in certification requirements.
