For Public Network

Any network adapter supported by a system running TCP/IP may be used to connect to the public network segments. You can install additional network adapters to support additional public network segments or to provide redundancy in the event of a faulty primary network adapter or switch port.

For Private Network

The private network connection to the nodes is provided by a different network adapter in each node. This network is used for intra-cluster communications. The following table describes the two possible private network configurations.

Method Hardware Components Connection

Network switch	Gigabit or 10 Gigabit Ethernet
	network adapters and switches

Depending on the hardware, connect the CAT5e CAT6, CAT6a, or CAT7 cables, the multi-mode optical cables with Local Connectors (LCs), or the twinax cables from the network adapters in the nodes to a switch.

Point-to-Point (two-node	Copper Gigabit network adapters	Connect a CAT5e or better (CAT6, CAT6a, or CAT7)

Copper 10 Gigabit Ethernet network adapters with RJ-45 connectors

Copper 10 Gigabit Ethernet network adapters with SFP+ connectors

Connect a CAT6 or better (CAT6a or CAT7) Ethernet cable between the network adapters in the nodes.

Connect a twinax cable between the network adapters in both nodes.
