Administrators can increase the number of VDI endpoints that run concurrent scanning by modifying the vdi.ini file. Trend Micro recommends strictly monitoring the effect of changing the VDI capacity to ensure that system resources can handle any increased scanning.

Procedure

  1. On the Apex One server computer, go to <Server installation folder>PCCSRV\Private\vdi.ini.
  2. Locate the [TaskController] settings.
    The default TaskController settings are as follows:
    • [TaskController]
      Controller_02_MaxConcurrentGuests=1
      Controller_03_MaxConcurrentGuests=3
      Where:
      • Controller_02_MaxConcurrentGuests=1 equals the maximum number of clients that can perform scans concurrently.
      • Controller_03_MaxConcurrentGuests=3 equals the maximum number of clients that can perform updates concurrently.
  3. Increase or decrease the count in each controller as necessary.
    The minimum value for all settings is 1.
    The maximum value for all settings is 65536.
  4. Save and close the vdi.ini file.
  5. Restart the Apex One Master Service.
  6. Monitor the CPU, memory, and disk usage resources of the VDI endpoints. Modify the controller settings further to increase/decrease the number of concurrent scans to best suit the VDI environment by repeating steps 1 to 5.
