Veritas NetBackup™ Flex Scale Installation and Configuration Guide

• a single instance of a highly-available NetBackup primary server across the cluster

• a single instance of the NetBackup media server per node

• a single instance of the NetBackup storage server per node

• 1 public IP address and 1 resolvable host name or Fully Qualified Domain Name (FQDN) for the NetBackup primary server

• 1 public IP address and 1 resolvable host name or FQDN for the NetBackup media server per node

• 1 IP address and 1 resolvable host name or FQDN for the NetBackup storage server per node

• 1 public IP address or the FQDN for the NetBackup Flex Scale cluster

• 1 public IP address and 1 resolvable host name or FQDN for the NetBackup Flex Scale management and API gateway server

  This is also the IP or name that you will use to access the NetBackup Flex Scale console UI.

• IP address details for the dedicated management network and IPMI (optional)

• 1 private IP and a private subnet for the internal communication between the cluster nodes

Note the following requirements:

• Private network NICs of all appliance nodes must connect to a dedicated switch or VLAN and should be separate from other networks, such as data network and management network.

• The network switch or switches need to be configured prior to configuring the appliance network interfaces.

• NetBackup Flex Scale uses IP address 172.16.X.X for private network NICs by default. If 172.16.x.x are reserved by the company, change private IP addresses to other local network addresses, such as 192.168.x.x or other subnets such as 172.20.x.x, when you run initial configuration from the GUI.

• It is recommended to use 25 Gb for both application (north-south network) and private (east-west network) networks, however 10 Gb may be used with the following caveats:

  • If using 25 Gb network for application network ( north-south network ), you must use 25 Gb for the east-west network as well. Using 10Gb for E-W is not supported in this case.

  • If using 10 Gb network for application network ( north-south network ), you can use 25 Gb or 10 Gb for the east-west network.

• IP address and subnet mask of the network gateway server from your existing network

• This is applicable if you are configuring the cluster using a yml file.

  If you have configured your network to use Virtual LANs then ensure that you provide the VLAN IDs in the yml file. Use the parameter vlan_id in the yml configuration template to specify the VLAN ID.

  For example, if network adapter eth1 is already tagged with a VLAN ID, you must specify that VLAN ID in the yml file. Here's a snippet from a sample yml configuration file that shows how to specify the VLAN ID:

  common_network_setting:
    data:
      bond:
        enable: true
        mode: balance-alb
        option: ''
      ipv4:
        gateway_ip: 10.xx.xx.1
        subnet_mask: 255.255.248.0
      ipv6:
        prefix_length: ''
        router_ip: ''
      vlan_id: '1200'

  Note:

  NetBackup Flex Scale does not block the cluster configuration if you do not specify the VLAN IDs. However, you may not be able to access the cluster nodes from the public network even after the cluster is configured successfully.

• 1 public IP address for the heartbeat on each site

• 1 public IP address for Veritas Volume Replicator (VVR) replication on each site
