Provision secondary interfaces (both nodes)​

Provisioning secondary interfaces is not strictly necessary. All that is required is an IP address reserved in the appropriate subnet for the purposes of serving as a virtual IP. However, provisioning secondary interfaces in a subnet used solely for SMB traffic allows server-client traffic to be segregated from storage traffic and reduces possible contention in high-performance use cases.
