SCT can be run in the actual production environment or a comparable test environment for planning purposes; however, JetStream DR software must be installed and configured prior to running SCT.

  • The SCT is written in Python and can be executed from the command-line or terminal.
    • Python Version: Any version of Python 3.
    • Platform: Windows and Linux.
    • Required Python Modules: jsonschema, requests, paramiko, pyvmomi, urllib3, pyyaml, boto3, minio, azure-storage-blob, tabulate.
      • The modules can be installed using the command: python3 -m pip install <module names>
  • Before running SCT, the vSphere statistics level should be changed to level 3 in vCenter to allow collection of required data (this may require additional "Performance.ModifyIntervals" privilege):
    • Using vSphere Client, navigate to the vCenter instance and adjust the statistics level:
      • Select the Configure tab.
      • Under Settings, select General.
      • Click Edit and then Statistics.
      • Change Statistics Level to 3.


NOTE: Use the vCenter option to “save” the statistics level change for only as long as you plan to collect statistics data using SCT. vCenter will then be able to automatically revert to its more secure default mode without additional interaction.
