Building EV11 in resilience

Hello all,

I am in the prosess of deploying fresh EV 11 into a multi-site environment (with Exchange 2013 DAG) and planning to have active/pasvie to have HA solution.

can you please recommend which clustering model to use:

using Veritas Cluster Server (VCS) 

or

using Windows Server Failover Clustering.

Also do you recommend deploying EV in VMWare platform or go for physical.
