can we connect single server to the multiple switches?

Hello Team,

I want to redesign the Client network in order to provide network availability and fail over. I have designed attached diagram. I have doubt if we can connect a server having multiple NICs to different uplink switches.

let say NIC1-2 is connected to Uplink Switch1 and NIC3-4 is connected to uplink Switch2. I want to do this so that if uplink switch1 dies then still server would be accessible via switch2.

is there would be any problem like mac address flapping? also, I know we can configure NIC teaming but i am not too sure how that would be helpful with my attached setup.

 

can you guys please look at the attached diagram and provide me your inputs?

 

Thanks for response.

It depends on what the server's multiple interfaces support.

The answer is that yes, it

The answer is that yes, it can be done but it depends on your existing network setup and what type of server you are using.

Have a read of the following documents:

I believe that modern NIC teaming allows a bonded group to be split across non stacked switch members, have a Single Layer 3 address but separate MAC addresses to ensure one L2 address does not flap between switches.
