Environment Requirements

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

Hardware Requirements

Table 1 lists the hardware requirements.

**Table 1** Hardware requirements
Item	Description
Server	Kunpeng server
Processor	Kunpeng 920
Drive	If a performance test needs to be performed, at least two drives are required: one system drive and one data drive. Use a SATA SSD or an NVMe SSD as the data drive for higher performance. If no performance test needs to be performed, the data directory can be created on the system drive. Configure the number of drives based on actual requirements.

OS Requirements

Run the cat /etc/*-release command to query the OS information.
Run the lscpu command to query the processor information.

Run the uname -r command to query the kernel version.

Run the uname -a command to query the environment information.
If you need to install an OS, choose Minimal Install and select Development Tools to minimize manual operations.
