Site aware cluster failover affinity

Failover Affinity

• Groups failover to a node within the same site, before failing to a node in a different site
• During Node Drain VMs are moved first to a node within the same site before being moved cross site
• The CSV load balancer will distribute within the same site

May I know Failover Affinity need further set after setting the faultdomain ?
