Network Configuration

The network configuration features enable you to create a variety of advanced network configurations using your physical network ports (including link aggregations), virtual NICs (VNICs), virtual LANs (VLANs), and multipathing groups. You can define any number of IPv4 and IPv6 addresses for these objects to connect to the various data services on the system.

The network configuration of an appliance has the following components. To configure networking, build datalinks on devices and build interfaces on datalinks. Select an object to view its relationship to other objects.

  • Devices - Network devices represent the physical network connections or IP over InfiniBand (IPoIB) partitions that correspond to your physical network. Network devices are created by the system and have no configurable settings.

    Devices that represent physical network interface card (NIC) ports on the controller are typically labeled igb0, igb1, igb2, and igb3. For example, device igb0 represents port NET-0 and device igb1 represents port NET-1. One NIC port per controller should be configured as a management interface.

    Devices that represent physical InfiniBand ports on the controller are typically labeled ibp0, ibp1, ibp2, and ibp3.

  • Datalinks - Datalinks are Layer 2 objects for sending and receiving packets for specific network devices. Use datalinks to apply settings such as LACP to network devices. Datalinks can correspond 1:1 with a device or IB partition, or you can define aggregation, VLAN, and VNIC datalinks composed of other devices and datalinks. Datalinks are required to complete network configuration, even if the datalinks do not apply specific settings to network devices. See Configuring Network Datalinks.

  • Interfaces - Interfaces are Layer 3 objects for IP, configuring IP addresses and other properties for datalinks. Each IP interface is associated with a single datalink, or is defined to be an IP network multipathing (IPMP) group comprising a pool of datalinks, which allows automatic migration of IP addresses from failed to working datalinks. See Configuring Network Interfaces.

    The following example shows configuration for a single IP address on a single port:

    • Device - igb0
    • Datalink - datalink1
    • Interface - hostname (IP-address/mask)

    The following example shows configuration for a 3-way link aggregation:

    • Devices - igb1, igb2, igb3
    • Datalink - aggr1 (LACP aggregation)
    • Interface - hostname (IP-address/mask)

  • Routing - IP routing configuration controls how the system will direct IP packets. See Configuring Network Routing.

To configure the network for the appliance, use the following sections:
