Cohesity Data Cloud for NetBackup™ Administrator's Guide

Network and DNS requirements

Configure the network, IP addressing, and DNS resolution to support communication between NetBackup components and the Cohesity cluster:

  • Assign one physical IP address for each node for node-level communication.

  • Configure one Cohesity virtual IP (VIP) per node for cluster services.

  • Configure one media server virtual IP (VIP) per node for media services access.

  • Define a single fully qualified domain name (FQDN) for Cohesity VIP resolution.

  • Define a unique fully qualified domain name (FQDN) for each media server VIP.

  • Ensure forward and reverse DNS resolution is configured correctly for all IP addresses and hostnames.

  • Verify that firewall rules allow all required network ports.

Proper VIP and DNS configuration is critical for cluster access, load balancing, and high availability in SpanFS environments.
