The ADS/ADS-Lite or non-server based OAS software does not come with, and does not require, device or user CALs. Only the server-based ADX or OAS requires CALs.

To avoid ADS/ADS-Lite or non-server based OAS connection and network communication performance issues, the number of users and the number of network engines and ADS/ADS-Lite or non-server based OAS computers that transfer trend data, event messages, and audit messages should not exceed 10. If a Metasys site with a single ADS/ADS-Lite or non-server based OAS configured as the Site Director and default repository exceeds that number of connections, consider one of the following options:

  • Configure one ADS/ADS-Lite or non-server based OAS to be the Site Director. Install and configure another ADS/ADS-Lite or non-server based OAS (or more) to provide the ADS repository function. When you install a separate ADS/ADS-Lite or non-server based OAS to provide the repository function, it allows you to dedicate five connections on the alternate ADS/OAS for system users and another five connections on the alternate ADS/ADS-Lite or non-server based OAS to network engines and ADS/ADS-Lite or non-server based OAS computers for transferring trend data, event messages, or audit messages.

    Note: The ADS/ADS-Lite or non-server based OAS cannot be the Site Director for another ADS/ADS-Lite or non-server based OAS of any type.
  • Upgrade to an ADX or server-based OAS . Configure the Windows Server of the ADX/OAS computer with the number of CALs equal to the total number of users and devices accessing the ADX/OAS .

Refer to the Metasys® System Configuration Guide (LIT-12011832) for performance guidelines and limitations.
