Hi,
We ran into a requirement where we need to mark a DataCenter or Cluster
as remote. This is for the feature Gluster Geo-replication management -
where the same oVirt instance will be managing both the master volume
and as well as the remote site volume
The reason we want to call out a Datacenter as remote, is to ensure that
the polling frequency on this is different from one that is co-located.
Is there a similar requirement for virtualization?
thanks

I thought in the gluster view there are no DCs, only clusters?
(actually, i wonder if we shouldn't consider the same for the virt use
case, and deprecate the DC entity, though that would be a major effort
and not sure worth it).
to your question, yes. there is a similar use case for virt - flagging a
DC or Cluster and Storage as remote for a DR use case.
though i don't think anyone spent cycles on modeling that

In fact, we were wondering if we need to bring in the concept of DC for
the gluster view and mark it remote...or just stick with flagging
cluster as Remote :)
Users may be more familiar with DC w.r.t DR

I think your second option looks better, considering gluster
does not
have any DC concept. Just stick with flagging cluster as Remote.
Once managed by RHSC (either local or remote), almost all features of
RHSC, should be applicable for that cluster as well. Isn't it?

If we do introduce a Remote cluster, how would that affect the Data
Center for virt+gluster mode - having remote as well as local cluster?
Thoughts?

Thoughts?
i dont see any problem having a cluster flagged as remote,
maybe we could use it also for different monitoring intervals if requested,
but as first phase it could be used only for the gluster use case.
