Abstract
A mechanism is provided for dynamic power and thermal capping in a flash storage system. A set of measurement values are received for the flash storage system, the set of measurement values comprising one or more of a set of current (I) measurement values, a set of voltage (V) measurement values, or a set of temperature (T) measurement values. An average current (I) value from the set of current (I) measurements and, responsive to the average current (I) value being greater than a predetermined maximum current (I) value, a determination is made as to whether a rate at which erase operations are performed for the flash storage system is greater than a predetermined minimum erase rate. Responsive to the rate at which erase operations are performed for the flash storage system being greater than the predetermined minimum erase rate, the rate at which erase operations are performed for the flash storage system are decreased by a predetermined value.
