Selector assessment of eligible server resources

To choose a server resource for a project or step, the system uses the selector to assess all eligible server resources:
  1. The system compiles a list of the servers that contain all the required variables in the selector. If no server resource matches the required selector criteria, then the project or step fails and the system creates a note.
  2. If more than one server resource meets the required criteria, the system rates each eligible server resource and assigns points as follows:
    • One point is given for each optional variable it matches. If the selector contains more than one copy of the same variable, the system assigns one point for each copy.
    • One point to the server resource that has the lowest BF_LOADRATIO value.
  3. The system chooses the server that received the most points. If more than one server resource has the most points, the system chooses from among them.

You can repeat optional variables in a selector. Doing so increases the score of a server that matches them. For example, to require memory of 1 GB but strongly prefer memory of 2 GB or more, you can set selector variables as follows:
