Preparing Hardware Devices

Currently, the HA supports two-node clusters only, and only one HA software package can be deployed on each device.

Supported Device Models

Table 1 lists the product and OS supported by HA.

OS

Atlas 500 AI edge station (model: 3000)

EulerOS 2.10 (AArch64)

Prerequisites

  • The two edge devices are able to communicate with each other.
  • The version number and system time of the HA software on the two edge devices are the same as those of the AtlasEdge software on which the HA software depends.
  • Before the deployment, the original HA-related processes are cleared on the edge device. Otherwise, the HA function of the two-node cluster will be affected.
    The system must support VRRP. If iptables disables VRRP, the Keepalived binary function will be abnormal and the HA system will fail.
    • VRRP: short for Virtual Router Redundancy Protocol.
    • iptables: network filter, which is a packet-filter-based firewall tool provided by the Linux OS.
