Exchange Server Role Requirements Calculator 8.3

Exchange 2010 Mailbox Role Sizing Calculator 16.4The Exchange team published an update for the Exchange Server Role Requirements Calculator, the tool to aid you in properly sizing your Exchange Server 2013 or Exchange Server 2016 deployment.

The new version number is 8.3, and it contains two major enhancements compared to version 7.9:

  • Added ability for the calculator to automatically determine the number of Mailbox servers and DAGs that need to be deployed to meet the chosen input requirements
  • Added Read from Passive support for Exchange 2016 deployments which results in decreased bandwidth utilization for HA copies

Exchange Server Role Requirements Calculator 7.8

Exchange 2010 Mailbox Role Sizing Calculator 16.4The Exchange team today published an update for the Exchange 2013 Server Role Requirements Calculator as well. The new version number is 7.8. This version incorporates sizing for Exchange 2016 as well and includes support for ReFS (default for Exchange 2016). The version number is also dropped from the calculator.

More or less complementary to the calculator is the updated sizing guidance for Exchange 2016, which was also published today here. No big changes here, apart from multi-role only option and a slight increase in CPU requirements to cover for unforeseen circumstances as the team is still learning from real-world behavior. This makes sense, looking at the speed in which the calculator was released compared to the one for Exchange 2013. Kudos to the Exchange team!

New and enhanced functionality since version 7.6:

  • Added support for Exchange 2016
  • Included CPU utilization guidance changes for Exchange 2016
  • Diskpart.ps1 and CreateDAG.ps1 now support ReFS
  • Moved DataMoveReplicationConstraint setting from CreateMBDatabases.ps1 to CreateMBDatabaseCopies.ps1
  • Revised all of the Distribution dialog controls to load their defaults from variables rather than use hard-coded values
  • The DAG name from the Input tab now flows through as the default on the Export DAG dialog
  • Updated Distribution tab dialog controls to persist the global catalog value during a session
  • Added conditional formatting for ReplayLagTime and SafetyNetThreshold
  • Removed 2013 from the name of the calculator

Fixes since version 7.6:

  • Fixed inaccuracies with “Number of Exchange Data Volumes per Server” input
  • Fixed calcActDBPDCWorst formula to take into account non-HA deployments
  • Fixed multiple dbs / volume calculation to take into account ReplayLagManager
  • Fixed calcNumDBCopyInSDC formula to take into account proper number of lagged copies
  • Fixed MaxPreferredActive not being displayed for A/A (Single DAG) site resilient solutions
  • Fixed an issue with Fail* buttons on Distribution tab when using some regional settings
  • Fixed an issue with volume path persistence on the Distribution tab Mount Points dialog

Exchange 2013 Server Role Requirements Calculator 6.6

Ex2013 LogoNote: Shortly after publishing, a minor update was made in to fix circular referencing in the sheet.

Next to an updated Exchange 2010 Server Role Requirements calculator, the Exchange team published an update for the Exchange 2013 Server Role Requirements Calculator as well. The new version number is 6.5.

This new version includes a nice new feature, courtesey of Excel, which will plot mailbox usage using the provided input. You can find this chart on the Mailbox Space Modeling tab.
