Is it possible to increase the connection speed using multiple NICs?

Question

Computer networks

Hello.
It became very interesting in what ways you can increase the speed between the server and clients.
One of the thoughts: if you increase the number of network cards on the server, you can increase the bandwidth (without changing the network environment) and as the load increases, the answer to the request comes from a freer card.
Example:
1 switch (with 25 ports), 10 clients and 1 server.
The server has 3 network cards (connected to the switch), everything else (clients and others) is connected to the same switch.
Can the server communicate through all NICs at the same time?
Implementation in the local network.

Answer 1

Channel bonding, EtherChannel, link aggregation, LACP 802.3ad. Different names, but the essence is the same. There are different schemes of work, a rake and support by iron.
Better than LACP, but the switch must be able to do it.

Answer 2

If the switch is smart and supports link aggregation , then you can.

Answer 3

Channel bonding - for Linux. + switch supporting Link Aggregation or IEEE 802.3ad.

Answer 4

Yes, this is called bonding.
Just keep in mind that one client (to be absolutely precise - one connection) will not go beyond the capabilities of one network card. Well, it should be taken into account that 4x10gbps cards will not give a performance of 40 gbps, in reality it will be about 30-35.
