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
Network switch
Point-to-Point (two-node
clusters only)
Hardware Components
Gigabit or 10 Gigabit Ethernet
network adapters and switches
Copper Gigabit network adapters
with RJ-45 connectors
Copper 10 Gigabit Ethernet network
adapters with RJ-45 connectors
Copper 10 Gigabit Ethernet network
adapters with SFP+ connectors

Connection
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.
Connect a CAT5e or better (CAT6, CAT6a, or CAT7)
Ethernet cable between the network adapters in
both nodes.
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.
