Network interface cards (NICs)

Each HCP node has two pairs of bonded ports:

One pair of ports is used for connecting to the front-end networks, including the [hcp_system] network and all user-defined networks. These ports share all front-end network IPv4 and IPv6 addresses assigned to the node.

One pair of ports is used for connecting to the back-end network. These ports share the back-end IP address assigned to the node.

The name assigned to each front-end and back-end port includes the NIC port number (for example, eth0 and eth1). By default, HCP uses the lower-numbered port in each bonded pair. If the lower-numbered port for a network fails, HCP automatically switches to the other port in the pair.

On the Storage Node page for a given node, the Console displays information about each of the NICs in the node. The NIC information is organized by network. For each port assigned to a network, the Console displays these details:

Interface — The name assigned to the port.

Active — An indication of whether the port is available for use. Possible values are true and false.

Duplex — An indication of whether the port is full-duplex (full) or half-duplex (half).

Active in Bond — An indication of whether the port is currently the one being used. Possible values are true and false.

Speed — The current rate of data transmission through the port.

Maximum Supported Speed — The maximum supported rate of data transmission for the port.
