Very high value for ``drs.max.migrations`` can result in management server
using up all of it's workers for DRS tasks
and not being able to execute other tasks.
+There are some advanced parameters that can be configured for DRS. These
paramters impact the way imbalance is calculated

+ * - ``drs.metric.type``
+ - `used`
+ - The metric type used to measure imbalance in a cluster. This can
completely change the imbalance value.
+ Possible values are free, used.
+ * - ``drs.metric.use.ratio``
+ - `true`
+ - Whether to use ratio of selected metric & total. Useful when the
cluster has hosts with different capacities.
+ * - ``drs.imbalance.condensed.skip.threshold``
+ - `0.95`
+ - Threshold to ignore the metric for a host while calculating the
imbalance to decide whether DRS is required for
+ a cluster.This is to avoid cases when the calculated imbalance gets
skewed due to a single host having a very
