More Information
Reset detection for different IO workloads
If different types of IO workloads are on the drive, then the test detects if there are any LUN, Target, or Bus resets. LUN reset is new to UAS devices and becomes costly if a reset needs to be performed. This is because a LUN reset to the device times out and a target reset gets sent to the device. The time lapse causes the drive to become unusable. This applies if you have synchronous workloads with varying transfer sizes for longer duration.
