Concept
A cluster connection is a management and service interface used by two NAS devices that form a high-availability (HA) cluster. It is a virtual interface that provides users with a unified access point (IP address or hostname) to connect to services on the cluster. In the event of a failure, when the roles of the nodes switch, the cluster connection automatically switches to the new active node, allowing users to continue accessing cluster services without any network configuration changes.
When creating an HA cluster, the network interface you select for the cluster connection will become the primary cluster interface. You can set up secondary cluster interfaces after the cluster is created by going to the "Settings" page in High Availability Manager.
Recommendation
When setting up the cluster connection during cluster creation, please note the following requirements and considerations:
- Use the same network interface on both NAS devices
- You must use the same network interface on both NAS devices.
For example, if you are using Adapter 1 on the active node device for the cluster connection, you must also use Adapter 1 on the passive node device for the cluster connection. - The network interfaces for the cluster connection cannot have vSwitch adapter bindings.
- Assign static IP addresses in the same subnet
- You must assign static IP addresses to the same network interface on both node devices.
- Ensure the two static IP addresses between the two node devices are in the same subnet.
- Connect both NAS devices to the same network switch
- The cluster connection should go through the same network switch. This ensures the stability and scalability of the cluster network while supporting multiple devices accessing the cluster services simultaneously.
- Ensure network speed and quality
- The speed and latency of the cluster connection directly impact the client access experience. It is crucial to ensure that the selected network cables and devices offer optimal performance, avoiding poor network quality or excessive latency that could affect the stability of the cluster services.

概念
Ac集群连接是两个NAS设备组成的高可用性（HA）群集的管理和服务接口。它是一个虚拟接口，为用户提供统一的访问点（IP地址或主机名）以连接到群集上的服务。在发生故障时，当节点角色切换时，群集连接会自动切换到新的活动节点，使用户无需进行任何网络配置更改即可继续访问群集服务。
创建HA 群集时，您选择的用于群集连接的网络接口将成为主要群集接口。您可以在High Availability Manager的“设置”页面中设置次要群集接口。
建议
在群集创建期间设置群集连接时，请注意以下要求和注意事项：
- 在两个NAS设备上使用相同的网络接口
- 您必须在两个NAS设备上使用相同的网络接口。
例如，如果您在活动节点设备上使用适配器1进行群集连接，则在被动节点设备上也必须使用适配器1进行群集连接。 - 用于群集连接的网络接口不能有vSwitch适配器绑定。
- 分配相同子网中的静态IP地址
- 您必须为两个节点设备上的相同网络接口分配静态IP地址。
- 确保两个节点设备之间的两个静态IP地址在同一子网中。
- 将两个NAS设备连接到同一个网络交换机
- 群集连接应通过同一个网络交换机。这确保了群集网络的稳定性和可扩展性，同时支持多个设备同时访问群集服务。
- 确保网络速度和质量
- 群集连接的速度和延迟直接影响客户端访问体验。确保所选网络电缆和设备提供最佳性能，避免网络质量差或过高的延迟影响群集服务的稳定性。
