Have we forgotten about management classes here
They allow you all the granularity you might need for offsite copies.
So beyond that you really only need only enough disk storage pools to cover your
varieties
of collocation/offsite copies at the sequential storage pool level.

Well, some of my clients want colocation, some don't.  Some of them want
offsites, some don't.  Some of them want to control their own e.g. maxscratch
(as a proxy for how much space they're using), some don't.

The offsites question is probably the most sticky to accomplish.  Until and
unless you can

BACK STG PRIMARY COPY node=foobar

then there's no real way to do the separation I'd desire with everyone in one
big stgpool.

Even then, you've got a management headache of keeping track of which nodes'
data should be backed up to which copy pools.

_I_'ve got the headache of which domain should be backed up where, but I don't
have so many of those.



Fred, how would you offsite one domain's data?
