Environmental Requirements

This document provides guidance based on the openEuler OS. Before performing operations, ensure that your software and hardware meet the requirements.

Test Networking

In the test networking, CX5 NICs and 25 Gbit/s or 10 Gbit/s optical modules are used. The server and client are directly connected or connected through a switch.
