In Ratio Algorithm, admin configure weight to each pool member depending upon the capacity of the server. So the no of connection requests sent to each pool member / server is according to assigned ratio. This method belongs to Static type of Load balancing as it is controlled by Administrator. Irrespective of server real time status/performance, the F5 will act according to the static ratio defined by Admin.
In Dynamic Ratio type, weight assigning decisions are taken by F5 itself. Assigned Ratio Weights are system generated. And it is based on various aspects of real-time server performance analysis. As this method is based on continuous monitoring of the servers, so ratio weights changes continuously.
Hope it helps!
