The feature that I have found most valuable is the redundancy, the failover solution. We have multiple servers running and there is no downtime. When one VM, virtual machine, is having an issue, it will automatically go to another host on the cluster. The clustering failover is the main advantage.
The ease of use of the configuration tools could be improved because it is quite complex to setup. The full infrastructure is quite difficult to setup and takes a lot of time to understand the components and be able to implement.
