3.4. Configuring Network

Virtuozzo Storage requires at least one network interface per server for management (that is, the management role). You will specify this network interface on the Component Installation screen and will not be able to remove the management role from it later (you will, however, be able to add more network roles to it).

Usually network is configured automatically (via DHCP) by the installation program. If you need to modify network settings, you can do so on the NETWORK & HOST NAME screen.

If manual configuration is required, specify the necessary parameters for at least one network card and provide a hostname: either a fully qualified domain name (hostname, domainname) or a short name (hostname).

3.4.1. Creating Bonded and Teamed Connections

Bonded and teamed connections offer increased throughput beyond the capabilities of a single network card as well as improved redundancy.

During installation, you can configure bonding on the NETWORK & HOSTNAME screen as described below. Teaming can be configured in a similar way after choosing Team on step 1.

  1. To add a new bonded connection, click the plus button in the bottom, select Bond from the drop-down list, and click Add.

  2. In the Editing Bond connection... window, set the following parameters:

    1. Mode to XOR.
    2. Link Monitoring to MII (recommended).
    3. Monitoring frequency, Link up delay, and Link down delay to 300.


    It is also recommended to manually set xmit_hash_policy to layer3+4 after the installation. For more information on network bonding, see Red Hat Enterprise Linux Deployment Guide and Linux Ethernet Bonding Driver HOWTO.

  3. In the Bonded connections section on the Bond tab, click Add.

  4. In the Choose a Connection Type window, select Ethernet from the in the drop-down list, and click Create.

  5. In the Editing bond slave... window, select a network interface to bond from the Device drop-down list.

  6. Configure other parameters if required and click Save.

  7. Repeat steps 3 to 7 for each network interface you need to add to the bonded connection.

  8. Configure other parameters if required and click Save.

The connection will appear in the list on the NETWORK & HOSTNAME screen.
