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? Thanks.

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. Nir
Hi, thanks for the info. So management network is used to deploy new images, but if I deploy the VM's from PXE server, I guess this is not needed, right? The storage network is clear. And then the entworks for the VM's I guess that are the networks with VLAN's, in my case, that will be used by the VM's. But, Which is the network for migrating VM's from one host to the other? Does it need to be non usable by the the VM's? Thanks. On 7/11/18 16:53, Nir Soffer wrote:

Thanks for the tips, I have set up one NIC on VLAN 1 for storage, one NIC on VLAN 1 for Migration , 1 NIC on VLAN 1 for MGMT and one NIV on multiples VLANs for VM's. Does it make sense or I will have routing issues for having multiple interfaces on the same VLAN with different IP's? Thanks. On 7/11/18 21:31, Alastair Neil wrote:

Having all networks on the same VLAN is almost the same as having one network on multiple nics (using bond). The later has the advantage of load balancing and redundancy options. When networks are separated, usually that is maintained on the local LAN/s as well (full L2 separation across your site). Having multiple interfaces on the same subnet is not a problem in Linux, but in some special scenarios you may encounter challenges. You will have to try it out. Thanks, Edy.
Thanks.
