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 the following port trunking modes:
- Cluster connection: Balance-alb (adaptive load balancing) and Balance-tlb (adaptive transmit load balancing)
- Heartbeat connection: Active-Backup, Balance-alb (adaptive load balancing), and Balance-tlb (adaptive transmit load balancing)
These modes 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 use the following port trunking modes:
- For the cluster connection: Balance-alb or Balance-tlb
- For the heartbeat connection: Active-Backup, Balance-alb, or Balance-tlb
- 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）的目的是尽量减少服务中断，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。端口中继结合了两个或多个网络接口，以增加带宽、负载平衡和容错能力。
注意
- 群集连接：Balance-alb（自适应负载平衡）和Balance-tlb（自适应传输负载平衡）
- 心跳连接：Active-Backup，Balance-alb（自适应负载平衡），以及Balance-tlb（自适应传输负载平衡）
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，您不能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，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。
- 进入网络与虚拟交换机 > 网络 > 接口。
- 点击+ 端口中继，然后点击添加。
将打开端口中继（添加）窗口。 - 选择两个或更多的网络接口添加到聚合组，然后点击下一步。
- 选择一个交换机类型，点击下一步，然后选择一个聚合模式。
- 对于群集连接：Balance-alb 或 Balance-tlb
- 对于心跳连接：Active-Backup、Balance-alb 或 Balance-tlb
- 点击应用，然后点击关闭。
- 可选：创建另一个聚合组。
- 在另一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匹配。 - 在 HA 设置期间选择端口中继接口。
- 前往活动节点。
- 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。
