  • Fixed run-time error on distribution tab when disabling site resilience
  • Fixed distribution error when disabling cross-site failover
  • Fixed bug in Distribution tab ActiveServer formula when modeling Cross Site Failover behavior

  • Added support for MaximumPreferredActiveDatabases and AutoDatabaseMountDial in Export DAG List function and createdag.ps1
  • Modified CreateMBDatabaseCopies.ps1 to remove sleep timer, improving copy creation significantly
  • Fixed createdag.ps1 to not generate an error when there is no alternate witness server provided

Version 6.6

  • Fixed circular logic issue with initial mailbox size calculation

Version 6.5

  • Fixed "Number of Exchange Data Volumes per Server" to support more than 50 volumes.
  • Optimized memory sizing for FAST which reduces memory requirements for small mailbox server designs.

  • Fixed 3 database/volume layout scenario involving 100 copies/server.
  • Fixed rounding error in calculating number of databases/volume in "2 Volumes / Backup Set"
  • Log isolation is now a calculated property to align with best practices guidance.
  • Changed "Disk" to "Vol" in left column of Distribution tab to align with scenarios that do not involve JBOD configurations.
  • Added additional processor core options.
  • Fixed JBOD storage design results table to accurately account for Restore Disk capacity being set to "--" and for differences between PDC and SDC Restore Disk capacity settings.
  • Fixed Backup Requirements worksheet to expose Weekly Full backups correctly.
  • Various comment changes/corrections.

Version 6.3

  • Fixed Backup Requirements calculations to include greater than 50 databases.
  • Added additional processor core support.
  • Fixed the number of database volumes calculation when disk count is specified.
  • Fixed the database size calculation for A/P scenarios to match A/A scenario calculations.
  • Fixed the calculator to take into account halving database number per volume in non-site resilient scenarios.
  • Fixed conditional formatting errors on transport configuration settings.
  • Fixed transport sizing to take into account mailbox growth.
  • Updated CAS megacycle calculations to align with SP1 guidance.
  • Revised Dispart.ps1 script to create database mount points consistent with JetStress performance counters.
  • Added Calculator version number to record one field three of CSV export files.

Version 6.1

  • Fixed operator mistake in calcNumActiveDBsSF formula
  • Fixed missed validation scenario where the calculator could recommend a copy count that could not be deployed on the custom disk architecture
  • Optimized remaining servers formula
  • Fixed an issue where single datacenter, multiple databases per volume architecture with lagged copies didn't calculate the correct number of
  • Fixed VirtCPUFactor reference
  • Various comment changes
  • Improved cell highlights for insufficient disk capacity on storage design tab
  • Added additional storage capacities – 1.2TB, 6TB and 8TB
  • Fixed database count validation logic to take into consideration dedicated lagged copy servers
