Dear all, I need your help to understand how to configure the network of a new oVirt cluster.
My new system will have a 4.3 engine that runs in a virtual machine, and some Dell R7525 AMD EPYC hypervisors, each holding two 4-port PCI network cards. These servers will have node-ovirt image again in version 4.3.
As for the network, there are two HPE Aruba 2540G, non-stackable, with 24 1Gbs ports and 2 10Gbs uplinks to the star center.
This is a simplified scheme:
My goal is to make the most of the server's 8 ethernet interfaces to have both reliability and maximum possible throughput.
This cluster will have two virtual networks, one for ovirt management and one for the traffic of individual virtual machines.
With that said here's what my idea is. I would like to have two links aggregated by 4Gbs, one for ovrtmgt and the other for vmnet.
With the ovirt web interface I can create an active-passive "Mode 1" bond, but this won't allow me to go beyond 1Gbs. Alternatively I could create a "Mode 4" bond 802.3ad but unfortunately the switches are not stacked and therefore not even this solution applies.
This is an example with active passive configuration:
Can you tell me if ovirt can generate nested bonds? Or do you have other solutions ?
Thanks a lot ! Best Regards Enrico
