Command syntax: Example: 9.0 DYNAMIC THROTTLING Dynamic throttling prevents unplanned or abrupt device shutdowns by lowering the IO performance of devices if power consumption and/ or temperature of increases. Dynamic throttling is split into parts: thermal and power throttling. 9.1 THERMAL THROTTLING Thermal throttling reduces IO performance of X8 Accelerator devices if temperature goes above the default threshold (T[throttle], default: 78°C). If temperature continues to increase and reaches 83°C the device is brought down to the lowest IO performance. If temperature reaches 85°C (T[offline]), the device completely shuts down. However, if device cools down and stays below T[throttle], the IO performance increases and brought back to maximum level. 9.2 POWER THROTTLING Power throttling reduces IO performance of X8 Accelerator devices if power consumption goes above the default threshold of 24W. It comes in 2 modes: turbo and compliant mode. In turbo mode throttling is disabled while in compliant mode the device is brought down to lower IO if power consumption exceeds threshold of 24W and stays above the threshold. When power consumption stays below the threshold value, IO performance increases and brought back - if possible, up to the maximum level. The throttling default settings: T[throttle], T[warning], T[offline], Turbo/ NOTE Compliant, Power Threshold, and IO Performance levels are done at factory.
