Abstract
Power is allocated to blades based on an estimate of the actual power they are expected to use rather than their maximum-power draw-value. To protect against situations where the estimated actual-power draw-value is exceeded, a hardware comparator monitors the blade system load against a predetermined threshold value set by a management module (MM) based on user input. If this threshold value is exceeded, a throttle latch is triggered, based on a signal from a service processor monitoring the blade system load. The output of this latch directly engages throttling. The service processor also monitors the output of the latch and communicates information regarding the throttling to the MM for evaluation.
