Additional NICs for VMware Network

Currently we have  8 network adapters and would like to provide maximum number of NICs for the Network Traffic.
What is the ideal number.

My current setup of vSwitch.

vSwitch0 =  Management Network, VMNetwork, VMKernel vMotion (Total 2 Nics)
vSwitch1 =  VM Network - iSCSi


1. I wish to have a separate switch for VMNetwork (Network Traffic)
Can I give 4 NICs to the Network Traffic.  Should I put them all under active or 3 active & 1 Standby.


2. If I try to create new switch for  Management + vMotion  and move from existing setup; will it have any impact on the Product servers.

A minimum of at least 2 network interfaces per service. To prevent a single point of failure.

Yes, you can have 4 network interfaces in a STATIC TRUNK, we would recommend ALL active, why go to the bother to cable, connect a network port, reserve a physical port on the switch, and just make it standby. Make all active!

2. If I try to create new switch for  Management + vMotion  and move from existing setup; will it have any impact on the Product servers.

Not if done carefully, it will not have any impact or outage. But this design should really have been done to the ESXi server before Production, the safest option would be to move all VMs to a different server, and then re-work the networking.

Ideally, you will require,

Management Network - 2 nics
vMotion - 2 nics
Storage Network - 2 nics
VM Nwetwork - 2 nics

so that uses all your network interfaces.

here is an example, no a suggestion of how your network should look

Prompt and excellent writeup  Andrew:      However, this is the error message I get when I try to add pNIC to an existing Switch or create a new switch.   "There is no active Physical network adapters for the switch"  Thanks.

Error when I try to create a new Switch or add new pNIC to an existing switch

do you have any spare network interfaces ?

I would check how many physical network interfaces are present and detected by the host, because that error message seems to indicate you have zero.

Where do I see for the Physical Network Interface?
This is what I see in VMware: Available pNICs  as seen in VMware
This is what is see in HP Onboard AdministratorESXi Host seen thru HP Onboard Administrator

That is where you would find your nice

But something is odd VMware ESXi does not seem to think they are valid and four nics in the HPE panel status are unknown

Have you checked physically you have 8!

If you connect on of those nics does it change from down?

You are correct Andrew - I went to the server room to check physically.  HP uses Flex Fabric/Virtual Connect.  One specific Ethernet port is not connected and that seems to be the problem.   I guess first I have to fix this; then consider adding the NICs.

Yes hardware specific issue check firmware driver version and hcl before proceeding
