Engine Upper and Lower Bounds

You can configure upper and lower bounds on the number of Engines that can be logged in at a given time. Set these upper and lower bounds on the Grid Components > Brokers > Broker Admin page. If the columns for bounds are hidden, add them using the Column control. The minimum value specifies that the balancer algorithm always leaves at least this amount of Engines (assuming there are this many) on the Broker unless the Engines are needed by Brokers in higher sharing tiers. The maximum value is the cap on the total amount of Engines to allow on the Broker. The balancing algorithms use both values.
