# Testing setup specifications

> Review the ABBYY bench test environment: FlexiCapture and database servers on virtual machines, SAS3 FileStorage, Processing Stations, and backend specs.

The FlexiCapture servers and the Database Server were installed on virtual machines.

All ABBYY FlexiCapture servers are installed on the same computer, which is connected to:

* The Database Server via a network interface with a bandwidth of 1 Gb/s
* FileStorage via SAS3 interface
* The external LAN via a network interface with a bandwidth of 1 Gb/s

All workload generators, Processing Stations, and the backend system are in the LAN.
