Re: [Users] Disk Migration
That sounds like a good idea. That is exactly what happens in my setup.
Whenever I move a disk it chokes out the management network

I guess that *not* using the migration network for storage operation
is the expected behavior, to make migration faster and safer.
Michal, Dan, can you elaborate on this?
with storage offloading it's probably not going to be significant, however
today it likely is.
Nir, why would not using migration network make it better? Won't we have the
same problem as before without migration network at all, i.e. choking the
management channel?
Should we maybe consider a dedicated "storage" network?
