Released: v19.9 of the Exchange 2010 Mailbox Server Role Requirements Calculator

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.

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?

How about fixing WNLB to work with 2010 cas servers.

great job on everything else.

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!
