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
