Hi,
I am new to oVirt and trying to deploy a cluster to see whether we can
move from VMWare to oVirt, but my first stopper is how to do a proper
design for the infrastructure,

how many networks do I need?, I have 2x10Gb SFP+ and 4x1Gb ethernet.

For storage we have NFS coming from Netapp and ceph.

Could someone point me in the right direction?

You can use 1G nic for the management network, but note that if you

want to upload and download images we use this network, so best have

a fast enough network for management.

You want separate network for storage (NFS/Ceph) - this your biggest

bottleneck.

Then you want a fast network for VMs. Migrating VMs from host to host

needs also fast network, but is not very common.

It depends also what the VMs are used for - database? desktops?

web servers? rendering nodes?

I guess you can learn from other users.
