The traditional DRS feature is based upon the current state of affairs and pertains to real-time performance and utilization. Predictive DRS take this one notch higher by integrating with vRealize Operations Manager and balancing the cluster based on past trends. In this recipe, we shall enable the feature and understand its nuances.
