    Glad to see the improvements. I'm wondering if there's anyway to add scalablity options into the calculator. An example would be, if I started with a environment of 1500 1GB mailboxes, but now need to scale it to handle 3000. Layout a plan to scale out current environment would be cool!

    How about fixing WNLB to work with 2010 cas servers.

    great job on everything else.

    Hi – I may be missing a trick here but I have entered

    Site Resilience User Distribution Model' = 'Active/Active (Single DAG)'

    'Number of Mailbox Servers Hosting Active Mailboxes / DAG (Primary Datacenter)' = 6

    'Total Number of HA Database Copy Instances (Includes Active Copy) within DAG' =2

    The Roles Requirements and Activation Scenario pages indicate 6 active servers in each data center

      Number of Active Mailboxes (Normal Run Time) 6038 6038

      Number of Mailbox Servers / DAG 6 6

    but the Distribution page indicates to me only 6 active servers with 2 active databases on each and therefore 6 servers with no active databases.  Am I doing something wrong?  Is there a bug?

    There are still issues with this calculator.  Did anyone else notice that the Tier-1 group if you change for instance desktop search value from yes to no and vice versa that the IOPS on the role requirements tab never change?  I had to stop using the Tier-1 section and use the other Tier 2-4 which seem to be fine.
