Haha it is rather crappy.
It was very cheap in comparison to Dell's and HP's etc at the time,
and it's over 6 years old now so it's done quite well considering the
price.
The brand is Cipherwave which I think is a rebrand of some other
brand, very basic GUI and features.
So is there no way to get data domain IOPS from the oVirt side?
Not that I know. As a nice integrated feature, oVirt is rather crappy
at that :) Getting IOPS and bandwidth would, I guess, require you to
install like collectd and send to a graphite or such server, or
simpler, just install e.g. bwm-ng on a host to get a quick snapshot.

Thanks!
