Tuning the Hardware

Checking Hardware Validity

Before installing and deploying the Docker container environment, ensure that:

• The hardware (including servers and NICs) is in the Kunpeng server compatibility list.
• The OS is in the Kunpeng server compatibility list. This document uses CentOS 7.6 as an example.
• The software (including the BIOS and BMC) is the latest version released on the Huawei enterprise support website.

Tuning the BIOS Configuration

• Purpose

  You can set some advanced options in the BIOS to effectively improve the performance of a Docker container. Table 1 describes the recommended performance-related BIOS configuration option on Kunpeng servers.

  Table 1 BIOS performance configuration options

  BIOS Configuration Option	Recommended Value	Description
  Custom Refresh Rate	Auto	Memory refresh rate. The default value is 32 ms. Choose Advanced > Memory Config > Custom Refresh Rate.

• Method

1. Restart the server, enter the BIOS, and choose Advanced > Memory Config > Custom Refresh Rate.

   

2. Set Custom Refresh Rate to Auto and press F10 to save the BIOS settings.

Tuning the DIMM Configuration

Use the Computing Product Memory Configuration Assistant to configure DIMMs.

The DIMM installation method recommended by the Intelligent Computing Product Memory Configuration Assistant is the optimal configuration. Asymmetric DIMM installation will cause frequent cross-NUMA memory access, resulting in performance deterioration.
