Adding FME Engines on a Separate Machine
You can add processing capacity to your FME Server by installing additional FME Engines on a separate computer from the FME Server Core.
The number of licensed FME Engines you can add is limited only by the host’s CPU and memory resources, which constrain the maximum concurrent request throughput.
The additional FME Engines can be of any architecture (32- or 64-bit) and installed to any supported operating system (Windows or Linux) - they do not have to match the specifications of the FME Server Core. It is important to note that the major versions must match - you should not install FME Server 2017 and try to add engines from FME Server 2016.
