Hyper-V Server with 4 nics how should I setup?
Posted on 2015-01-14
We have 2 Dell r620's with 4 nics each. We don't have a SAN so will be using veeam backup for backing up machines instead of clustering and will replicate to a remote site for disaster recovery.
We only have cisco sg300 switches so cannot teamed nics across switches.
I'm just not quite sure how to setup the nics....
I was thinking
Nic1 mgmt switch a
Nic2 team for vms switch a
Nic3 team for vms switch a
Nic4 failover (if switch a goes down) switch b
So I set this up vswitch a without management os sharing enabled for the teamed vms and then vswitch b with management sharing enabled using nic4
Problem is now there are 2 dns entries for the hyper v server. When I ping the servername sometimes i get a reply from 1 ip and sometimes from the other. In bindings I set the vswitch as the top option.
This means that if the I setup a vm with enabled nic's on vswitch a and b, traffic will go via either? I want vswitch b enabled just in case i'm not around when switch a went down.
So now I'm thinking why not just have
nic1 team switch a
nic2 team switch a
nic 3 team switch b
nic 4 team switch b
then enable the management sharing with os on both vswitches? that way which ever route they take the traffic will be going via the teamed nics?
Ideally I would like the first setup but traffic on vswitchb to only be enabled if switcha went down but I don't think that's possible!
