Hey everyone...

Why do servers usually have to NICs? Is it so that they can be configured to be used on 2 different subnets??

thanks!

Servers can be installed with two NIC's for a variety of reasons. It all depends on the roles that they are configured for.

You may have two NIC's configured as a 'Team' to load balance the traffic that the server receives, or it may be for fault tolerance.

If the server is a Router it may have an internal interface, and an external interface, and act as a gateway to the internet.

 

All ours have n number of network connections.

They then have n+1 number of network cards (or ports) for redundancy

Web servers have an internal (for managment) and external (http port) interface and have 3 NICs for example.
