Exchange Server Role Requirements Calculator by Exchange Server Team is a tool that all Microsoft Exchange Server administrators should know about and have used at some point in their life.
Initially released as Mailbox Server Role Calculator, this handy tool got re-branded as Exchange Server Role Requirements Calculator in 2013. And Over the years, the tool helped many administrators with the sizing of server specification for various Exchange Server roles.
Recently, the Exchange Server team released the version 8.3 of the Exchange Server Role Requirements Calculator. The latest version focuses around two specific enhancements.
- Exchange 2016 designs now take into account the CU3 improvement that reduces the bandwidth required between active and passive HA copies as the local search instance can read data from its local database copy.
- The calculator now supports the ability to automatically calculate the number of DAGs and the corresponding number of Mailbox servers that should be deployed to support the defined requirements. This process takes into account memory, CPU cores, and disk configuration when determining the optimal configuration, ensuring that recommended thresholds are not exceeded.
