[cisco-voip] Unity and Exchange

For that model server MCS-7835-H1 the spec sheet list 2000 mailboxes
with 42 ports.  Not sure if cisco licensing knows the server spec and
will issue licenses.  I seem to recall cisco doesn't have a way to
verify hardware with licenses. Eg you can put 120 ports on a 7825
overlay 1 and they don't know you got a 7825 when you should have a
overlay 3, etc.

Recall the platform overlay 1, 2, 3 setups for Unity in the installation
guide.

Our Exchange offbox servers are the Cisco MCS7845H-EVV1 (HP DL380-G3 )
machines and we also have about 2000 voice mail users per each server.
We have 2 standalone DC/GC servers though. Since cpu utilization is low
on our G3 servers I would say a DL380-G4 should support up to 3000 voice
mail only subscribers without issues.

We also keep deleted messages for 5 days and do the message store
defragmentation once every year which helps in performance and increase
a free disk space.

Hello All,

Running Unity 4.05 with Failover,  Exchange 2000 offbox,  Voice Mail
only config.  My Exchange boxes are DL380 G4's with dual cpu with a lot
of disk space left.  Wondering how many exchange mailboxes these servers
will support before I need to add new Exchange servers. I currently have
about 2000 users on each server and my exchange data base runs about 8 -
9 gb on each server. These servers also act as the DC/GC's for the Unity
standalone AD domain.  I am having no issues but need to plan for the
future. I expect to be upgrading to Unity 7 next year.

Thanks!

Steve
