Quick Answer: Why Does A Server Have Two NICs?

Separation of traffic (i.e.

you could have a combo web/database server, same network, put all web traffic on one NIC, db traffic on the other, makes it easier to calculate loads for traffic types).

This also makes it easier to split the two later on, nobody has to change connection strings.

Can a server use multiple NIC?

Configuring two or more NICs on the same subnet may cause communication problems. One of the most common scenarios resulting in multiple NICs being assigned to the same subnet is when both a wired and wireless interface are used to connect to the same network.

How many NICs Can a server have?

2 NICs

How do you use dual NICs?

Steps to Configure Dual NICs

  • Open Control Center and navigate to Settings > Network Settings tab and click the “Edit” button next to the second network interface intended to be used for the subnet.
  • Select the “Manual Network Config” option and configure the static address of the network card to the desired address.

Why do servers have multiple Ethernet ports?

In a network redundancy application, a dual Ethernet device is connected to two separate networks in order to reduce traffic or load on one of these networks. This effectively allows users on both networks to easily access the dual Ethernet device in order to communicate with devices on either of the two networks.

Can two network interfaces have the same IP address?

You cannot use the same IP address on multiple interfaces. It just won’t work properly (usually it will only work on the last interface the IP was assigned on). You need to put the ethernet interfaces into a bridge and assign the IP address on the bridge itself.

What is a NIC on a server?

Every computer on a network, both clients and servers, requires a network interface card (or NIC) in order to access the network. A NIC is usually a separate adapter card that slides into one of the server’s motherboard expansion slots. However, the NIC in a server computer connects many network users to the server.
