I misspoke . . .we have DD880's.  It's limit is 180 sessions.

The manual states the limit rather strangely . . It says:

Platform  Ram  Total  Max   Max Write    Max    Mixed
                      Write with OptDup  Read
DD880    64gb   180   180      90        50     <= 180 writes and
                                                <= 50 reads

This seems to say there is a MAX of only 50 read sessions.  In asking for
a clarification about this I was told that it's basically 180 sessions max
of any combined type, and this includes replication sessions.  It doesn't
read that way, but that's what I was told.  Oh - "OptDup" is low bandwidth
optimization for replication - something to help really, really slow
replication connections.
