Server mode is used for distributed testing. This Testing works as client-server model.

By running JMeter remotely, you can replicate a test across many low-end computers and thus simulate a larger load on the server. One instance of the JMeter client can control any number of remote JMeter instances, and collect all the data from them.
After navigating to JMeter directory, Type below command to start JMeter in Server mode:
