exchange 2010 UM sizing RRS feed

  • Question

  • I am curious how i should architect our UM environment. Currently we are running Cisco Unity 5, and we have about 2000 users in this location.  I have been asked to come up with a configuration (hw and sw) to switch to 2010 UM, which we would also integrate with OCS 2007 R2. Our 2010 environment is sized to support 2400 users via 2 mailbox servers (DAG), and 2 cas/hub servers (array).

     

    Any tips/tricks for exchange 2010 UM, I have never played with that role before.

  • In addition to the correct information from Mahmoud above, check out the Exchange Server 2010 Design and Architecture at Microsoft technical white paper, page 53 onward to see how many MSFT use.

    We have 3500 users and use two UM servers in different datacenters/same site located next to call managers, simple for redundancy. We use CUCM Version 7.1 and the document Exchange 2010 UM PBX Config Note for CUCM 7.0 would have helped us during implementation. I've seen threads where someone has had issues with 7.0 but any issues were resolved when they also moved to 7.1.
