Microsoft has released version 12.3 of the Exchange 2010 Mailbox Server Role Requirements Calculator. Two main improvements that caught my attention are the following.
- The calculator now supports Active/Active user distribution model. You have three options in the calculator – Active/Passive, Active/Active (Single DAG) & Active/Active (Multiple DAG).
- A new worksheet that documents the Activation Scenarios for DAG deployment.
