It’s almost a year since the last update, but today the Exchange Team released version 20.6 of the Exchange 2010 Mailbox Role Calculator. The new name is Server Role Requirements, since 20.6 can also dimension Hub Transport or Client Access roles.
Enhancements since version 19.9:
Calculator now supports defining server requirements for dedicated Hub Transport and Client Access servers; specifically CPU and memory sizing.
Calculator will state how many dedicated Hub Transport and Client Access servers should be deployed in a datacenter.
Calculator now includes Hub Transport and Client Access impact on server megacycles and utilization calculations for multi-role deployments.
Global catalog processor core calculations were optimized and simplified.
Calculator has been rebranded as Exchange 2010 Server Role Requirements Calculator.
Fixed column headers in results tables to match Site Resilience scenario
Bug Fixes since version 19.9:
- Fixed conditional formatting bug when site resilience is not enabled, yet SDC instance input has greater than 0 copies specified.
- Fixed logic error where calculator would calculate storage requirements when there were more database copies (HA+Lagged) than Mailbox servers.
- Fixed logic error in calculating remaining active databases during first and second server failures in secondary datacenter for single DAG A/A scenario.
- Fixed /environment formula for standalone number of database formula.
