Adding another NIC to Hyper-V
-
I have a server with 8 GB Network cards. It is currently setup with only 1 NIC in use. Physical NIC shared with Hyper-V virtual NICs
It's a physical server with 2 Hyper-V machines.
In order to get better network speed is it going to help to add another NIC if ultimately it's going into the same switch?
-
What are 8 GB cards?
-
Do you mean 8Gb/s FC?
-
My bad - QTY (8) 1GB Cards...
-
Fibre Channel can definitely be bonded. That's how we get speeds above 16Gb/s.

Oh, yes, you can bond those two to a maximum of four. There are diminishing returns so people rarely bond more than two and basically never more than four, expecially as 10Gb/s Ethethnet is cheaper than quad bonded GigE.
Your switch should be hundreds or thousands of times faster than any port on it, so bonding is very effective.

Ok, so set up NIC Teaming on the Physical Server then?

Yes

Since 1 NIC is setup for the Hyper-V Virtual NIC, can I just team another physical one with the current physical NIC or will I need to remove or reconfigure the Hyper-V?
-
To clarify, I have done NIC teaming before many times, but that was before setting up the hyper-v virtual NIC and before the machine was in production.

You would typically set up the NIC teaming on the host.
Then in Hyper-V, you create a virtual NIC using one of the host's teams.

Tim,
Let me re-phrase.
I have to setup NIC teaming, but there is already the Hyper-V virtual NIC in place.
If I setup NIC teaming on the host, will it break the Hyper-V NIC?

Yes.
Schedule some planned down-time to make the changes, or you can change the host NIC that the Hyper-V NIC uses. Doing the latter will cause only a blip, if at all.
Or create a team of NICs on the host that the Hyper-V NIC isn't using, then you can go into the Hyper-V NIC properties and switch it over quick.

Ok, thanks.

Make a team using one of the other Nick’s with just the one Nick in the teen make sure it all works then go into hyper V and change the D switch to the team make sure everything works then go on at the Nick it was already in use to the team
