Concept
The purpose of high availability (HA) is to minimize service interruptions and ensure the continuous availability of services and storage. To achieve this, an HA cluster requires stable and reliable cluster and heartbeat connections. The cluster connection allows remote clients to access the cluster, while the heartbeat connect allows data synchronization between the nodes of the cluster, so that one node can take over services if the other node fails.
To enhance the performance and redundancy of these connections, we recommend configuring port trunking for the network interfaces used for these connections. Port trunking combines two or more network interfaces for increased bandwidth, load balancing, and fault tolerance.
Note
HA does not support port trunking modes Balance-alb (active load balancing) and Balance-tlb (transit load balancing).
These modes modify MAC addresses dynamically and disrupt HA communication and failover stability.
Procedure
Important
- You must complete all port trunking configurations on both nodes before you create the HA cluster.
After the cluster is created, you cannot configure or modify the port trunking settings. - You must configure port trunking on the same ports on both nodes of the cluster, and the setup order must be identical.
- Configure port trunking on one node.
- Log into a node as an administrator.
- Go to Network & Virtual Switch > Network > Interfaces.
- Click + Port Trunking, and then click Add.
The Port Trunking (Add) window opens. - Select two or more network interfaces to add to the trunking group, and then click Next.
- Select a switch type, click Next, and then select a trunking mode.
Important
You cannot set the port trunking mode to Balance-alb (active load balancing) or Balance-tlb (transit load balancing).
- Click Apply, and then click Close.
- Optional: Create another trunking group.
- Configure port trunking on the other node, using the same steps and settings.
Make sure the port trunking configurations match exactly between the nodes. - Select port trunking interfaces during HA setup.
- Go to the active node.
- Open High Availability Manager.
- Click Create a Cluster Now, and then click Next.
- Select port trunking interfaces for the cluster and heartbeat connections.
- Follow the on-screen instructions to complete the cluster creation process.

概念
高可用性 (HA) 的目的是减少服务中断并确保服务和 存储 的持续可用性。为实现这一目标,HA 群集 需要稳定可靠的 群集 和心跳连接。群集 连接允许远程客户端访问 群集,而心跳连接则允许 群集 节点之间的数据同步,以便在一个节点故障时另一个节点可以接管服务。
为了提高这些连接的性能和冗余性,我们建议为这些连接使用的网络接口配置 端口中继。端口中继 将两个或多个网络接口组合以增加带宽、负载平衡 和容错能力。
注意
HA 不支持 端口中继 模式 Balance-alb (主动 负载平衡) 和 Balance-tlb (过渡 负载平衡)。
这些模式动态修改 MAC 地址,扰乱 HA 通信和 故障转移 稳定性。
步骤
重要
- 在创建 HA 群集 之前,必须在两个节点上完成所有 端口中继 配置。
创建 群集 后,您无法配置或修改 端口中继 设置。 - 必须在 群集 的两个节点上的相同端口上配置 端口中继,并且设置顺序必须相同。
- 在一个节点上配置 端口中继。
- 以 管理员 身份登录节点。
- 前往网络与虚拟交换机>网络 > 接口.
- 点击 + 端口中继,然后点击 添加。
打开 端口中继 (添加) 窗口。 - 选择两个或多个网络接口添加到汇聚组,然后点击下一步.
- 选择一个交换机类型,点击下一步, 然后选择一个汇聚模式。
重要
您不能将 端口中继 模式设置为平衡-alb(活动 负载平衡)或平衡-tlb(传输 负载平衡)。
- 点击应用, 然后点击关闭.
- 可选:创建另一个中继组。
- 在另一个节点上配置 端口中继,使用相同的步骤和设置。
确保节点之间的 端口中继 配置完全匹配。 - 在 HA 设置期间选择 端口中继 接口。
- 转到活动节点。
- 打开 High Availability Manager。
- 点击立即创建一个 群集, 然后点击下一步.
- 为 群集 和心跳连接选择 端口中继 接口。
- 按照屏幕上的说明完成 群集 创建过程。
