N+1 Failover with Weighting

An organization has four groups using all available Engines in a grid. One group has a guaranteed allocation of at least half of the grid any time it needs it, and the other three groups share the remaining Engines.

•

Brokers  Set up five Brokers. Each group gets a Broker, plus one is used for failover.

•

Drivers  Create four roles, one for each group. In each role, set the Manager List value to the group’s Broker and the failover Broker. Assign the roles to the appropriate users.

•

Engines  Use the weight-based Engine Balancer. Adjust Engine Weight on the Broker Admin page so the first group’s Broker is weighted at 3.0, and the other three groups’ Brokers are weighted as 1.0. Set the failover Broker weight at 1.0, so that a group is not assigned any more resources than normal if their Broker goes down.
