We have 3 VMware servers running in a cluster using Virtual Center. They all run ESX 4.0. They each have two network cards. One attaches to our Procurve switch in the normal network and the other attaches to the Procurve switch on a special test VLAN. We have a Cisco router that currently manages traffic to/from this VLAN.
That test VLAN doesn't get much use so Ihate wasting an entire gig network card for that limited traffic. I'd like to avoid dedicating that nic just to that traffic.
My question is :
I know I can set up a virtual switch in Virtual Center that tags traffic for our test VLAN. Can I take those VMware hosts and plug them into the regular user network and just rely on VMware to tag that traffic for the VLAN? Can I just add both VLANS to the physical ports on the Procurve VMware hosts plug into and let the VLAN tags applied to the packets by the virtual switch manage which traffic is normal-network/VLAN?
I am trying to avoid tying up a whole NIC for just the light traffic that is needed for that VLAN.
Please let me know if I need to clarify anything.
