Unity Server co-location with Exchange server

[ysloh]

Hi

With reference to the Unity Design guide, under the "Physical Placement and Network Infrastructure" section it is stated that the Unity needs to be placed in the same data centre as :

”Every Exchange server on which mailboxes for that Cisco Unity server are homed. If Cisco Unity is separated by a WAN from an Exchange server on which subscriber mailboxes are homed, a second Cisco Unity server must be co-located with the remote Exchange server."

Would like to understand, if a additional Unity server is required (in the remote office) in the following scenario.

- Unity (UM) and Partner Exchange servers are located in the same data centre (HQ)

- Group A of users have their message store in the partner Exchange server (in HQ).

- Group B of users have their message store setup in another Exchange server in a remote office.

You need another Unity server at the remote site if the remote site users have their mail boxes on an Exchange server local to that site. You cannot separate Unity from exchange over the WAN, hence if you have two sites, HQ with exchange and 1 remote with exchange and both need Unity UM, then you need a Unity server local to each site

Just as a FYI If your customer is a CUWL customer then you are licensed for as many copies of Unity as you need, so you would only need to pay for the hardware.
