With coverage-managed databases, however, you could properly rank server swimming pools through the enterprise requirement of the workloads that they are functioning utilizing the MIN_SIZE, MAX_SIZE, and IMPORTANCE server pool characteristics. When the failure of a server delivers a server pool to below its configured minimum range of servers, Yet another server will transfer from a less significant server pool to take its area and bring the quantity of servers again up to the configured least.
