THERMAL MITIGATION USING SELECTIVE I/O THROTTLING

摘要

A method and apparatus of a device that manages a thermal profile of a device by selectively throttling input/output operations of the device is described. In an exemplary embodiment, the device monitors the thermal profile of the device, where the device executes a plurality of processes that utilize storage of the device. In addition, the plurality of processes include a high priority process and a low priority process. If the thermal profile of the device exceeds a thermal threshold, the device decreases a first bandwidth range for the low priority process and maintains a second bandwidth range for the high priority process. The device further processes a storage request of the low priority process using the first bandwidth range and processing a storage request of the high priority process using the second bandwidth range.

1. A non-transitory machine-readable medium having executable instructions to cause one or more processing units to perform a method to manage a thermal profile of a device, the method comprising:
monitoring the thermal profile of the device, wherein the device is executing a plurality of input/output operations that utilize storage of the device, the plurality of input/output operations including a high priority input/output operation and a low priority input/output operation; if the thermal profile of the device exceeds a first thermal threshold,
decreasing a first bandwidth range for the input/output operation, andmaintaining a second bandwidth range for the input/output operation; processing a storage request of the low priority input/output operation using the first bandwidth range; and processing a storage request of the high priority input/output operation using the second bandwidth range.
