There are many variables to consider (CPU, memory, hard drive/SSD, application being tested, etc.) when determining how many servers you will need.

When I needed to run a 500 users load test, I first started with one injector server. I created my scenario and ran a test with 5 users. I then incremented up to 10 users, then 20 and so on. After each test, I checked the Injector metrics (this is available under Test Analysis tab in AppLoader). This way I was able to determine that the injector machine could handle 50 users. I then cloned it to create the additional injector servers in order to reach the 500 users that I needed.
