Virtualized
Servers
- VTScada can run on virtual Servers.
- Don’t clone virtual servers with VTScada installed. To learn more, search ‘virtual servers’ in VTScada Help.

Other
Recommendations
- If you need RS-232 ports to communicate with legacy devices, we recommend Ethernet to serial converters.
- Keep VTScada & History data on separate drive from OS.
- NetDDE is not available on Vista and higher (removed in XP Service Pack II).
- VTScada uses IANA registered TCP/IP port 5780. Set up firewalls to route RPC traffic accordingly.
- Configure RAID with standard or solid-state drives. SSDs provides better performance.
