SCOM 2012 RMS

RMS is dead. Scalibality is an applicable option now and allowing multiple management servers to balance the functionality that the RMS used to provide alone should also increase scalability.

Microsoft takes a different approach in Operations Manager 2012, and removes the
RMS role. Instead, there is a pool of management servers. The work previously performed by the RMS is managed by this pool, which is a logical grouping of multiple health services instances. In this peer-to-peer topology, all management servers act as equals. The workload is distributed across multiple management services. Should a management server in the pool become unavailable, its workload is moved elsewhere in the pool. This gives automatic fault tolerance and load balancing.
Operations Manager 2012 provides topology simplification by removing the RMS and introducing of the All Management Servers Pool.
