NetBackup Flex Scale network cabling
Review the following cabling information and ensure that the nodes are cabled correctly before you add a new node to the cluster or replace an unhealthy node in the cluster with a new node.
Management network
The eth1 1 GbE network interface on each node provides access to the management network. Connect the eth1 network interface to a switch.
Private network
The eth4 and eth6 25 GbE network interfaces on each node provide access to the private network and are used by the nodes in the cluster to communicate with each other. Veritas recommends using two separate Ethernet switches, which are capable of supporting 25 Gb link to isolate the eth4 and eth6 interfaces. If you use a single Ethernet switch, connect the eth4 and eth6 interfaces of each node to switch ports in a separate VLAN. Network bonding cannot be configured for these interfaces.
Public or the data network
The eth5 and eth7 10/25 GbE network interfaces on each node provide access to the public data network, which is used to run production workloads. If the public network and the management network (eth1) are in the same network, connect the eth5, eth7, and eth1 network interfaces to a single Ethernet switch capable of supporting 10/25 Gb link.
If the public network and the management network are in a different network, connect the eth5, eth7, and eth1 network interfaces to separate Ethernet switches capable of supporting 10/25 Gb link.
The eth5 and eth7 network interfaces can be used individually or can be bonded. If you configure a network bond, the required settings must be configured on the switch.
Use two power cables to connect the dual power supply modules of the node to dual Power Distribution Units (PDUs).
