Re: [ovirt-users] Ovirt nodes NFS connection
Hello Tal
It seems you have a very big overkill on your environment. I would say that
normally 2 x 10Gb interfaces can do A LOT for nodes with proper redundancy.
Just creating Vlans you can separate traffic and apply, if necessary, QoS
per Vlan to guarantee which one is more priority.
If you have 2 x 10Gb in a LACP 802.3ad Aggregation in theory you can do
20Gbps of aggregated traffic. If you have 10Gb of constant storage traffic
it is already huge, so I normally consider that Storage will not go over a
few Gbps and VMs another few Gb which fit perfectly within even 10Gb
The only exception I would make is if you have a very intensive (and I am
not talking about IOPS, but throughput) from your storage then may be worth
to have 2 x 10Gb for Storage and 2 x 10Gb for all other networks
(Managment, VMs Traffic, Migration(with cap on traffic), etc).

I'm not sure how you'd get more throughout than you can get in a single
physical link. You will get redundancy.
Of course, on the storage side you might benefit from multiple bonded
interfaces.

Interesting - but I assume it'll still stick to a single physical link.
Y.
