Server Stateless Computing Management Introduction

Server Stateless Computing Management Introduction


The stateless computing function separates server hardware from hardware attributes to automatically deploy and replace servers and migrate services.

Stateless computing does not require server reconfiguration, making computing stateless and enabling plug-and-play.


Stateless computing enables fast server hardware configuration replacement and automatic service migration.

Stateless computing implements the following functions:

  • Domain management

    Administrators can quickly associate stateless computing servers with profiles or group profiles.

  • Configuration item management

    Administrators can configure pools, adapters, BIOS policies, and VLAN groups to implement unified hardware configuration for stateless computing servers.

  • Profile management

    Administrators can configure different combinations of pools, adapters, and BIOS policies in profiles or group profiles, and use the profiles or group profiles to implement fast configuration and deployment for new servers.

  • Automatic migration management

    Automatic migration separates server hardware from its configuration, automatically migrates the configuration to a new server, and activates the new server to run services, ensuring service continuity.

Application Restrictions

Application restrictions on stateless computing are as follows:

  • This function applies only to Huawei rack, blade, and high-density servers.
  • After configuring stateless computing for a server, you must manually back up the configuration immediately. Otherwise, if the backup data before the configuration is used for recovery, information between eSight and the server is inconsistent, the profile is repeatedly allocated, or configuration conflicts occur on the device. As a result, services are affected.
  • Server restart will occur during domain activation, profile association, group profile association, splitting or deletion of devices associated with profiles, deletion of domains containing associated profiles, automatic configuration migration, manual configuration migration, and profile exporting from devices. As a result, services are interrupted.
