What are the best practices for setup of the ring network in a cluster or Metro cluster Genesis ZX?

THe Ring network is like a heartbeat or cluster communication network.  It has the following best practices

 

1. Must use a switch or multiple switches.  It is not designed to go straight connect between nodes. 

2. Use a Bond for network cable/port failover

3. Setup "Balance alb" which is bonding mode 6 in the Genesis ZX GUI for the ring network.  Other networks can have a different bonding mode, however the ring must be Balance alb

4. Ring network pings must always give better than < 1ms results as latency is more important than throughput.  Therefore if you see higher latencies then you can be sure that the ring will not be working optimally.
