To calculate the FindFace Enterprise Server host(s) characteristics, use the requirements provided in this chapter.

.. tip::
   Be sure to learn about the FindFace Enterprise Server :ref:`architecture <architecture>` first.

Basic Configuration
===============================

.. important::
   If the resolution of a camera(s) in use is more than 1280x720px, it is strongly recommended to use the GPU-accelerated package ``findface-video-worker-gpu``. 

.. note::
   When designing your system architecture in a cluster environment, bear in mind that the number of ``findface-tarantool-server`` shards on a single host must not exceed the number of CPU memory channels, multiplied by 2.
