  • 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.

Ex2013 LogoOnly 10 days after the release of the first public version of the Exchange 2013 Server Role Requirements Calculator, the calculator gets an update. The new version number is 5.6.

Changes since version 5.1:

  • Optimized Volume Design Architecture Formula
  • Fixed Recommended Min Number of GC Cores (Secondary Datacenter)” calculation to use SDC instead of PDC CAS count.
  • Fixed CPU comments and removed erroneous information.
  • Fixed multiple conditional formatting bugs.
  • Fixed problem where this workbook had to be the active workbook at all times.
  • Fixed problem with extra-wide Fail Server button on the distribution worksheet.
  • Enabled variable based tracing.

Exchange 2013 Server Role Requirements Calculator v5.1


Ex2013 LogoIt’s been long wait since the release of Exchange 2013, but today the Exchange Team finally released the first version of the Exchange 2013 Server Role Requirements Calculator. This initial release is numbered version 5.1.

Some of the highlights over the Exchange 2010 calculator, mostly due to changes in the architecture, are:

  • The calculator includes transport sizing (hence the name, I guess);
  • Accommodating for Client Access Server role with sizing for multi-role server deployments;
  • Support for multiple databases / JBOD volumes;
  • Configurable witness server location (primary, secondary or tertiary data center);
  • Configurable server names and database prefixes for generated scripts;
  • Generated scripts include script for DAG creation;
  • Support for single HA, Act/Pas and Act/Act distribution models.
