Concept
In a high-availability (HA) cluster, a cluster IP address is a virtual IP address used as the main access point for clients connecting to the cluster.
This IP address represents the entire cluster rather than a specific physical device within the cluster. When a failover occurs—meaning the active node device fails and the passive node device takes over as the new active node—the cluster IP address automatically migrates to the new active node. This allows clients to continue to access services without changing any network settings. This seamless IP address handover ensures service continuity, simplifying both IT maintenance and client access.
Recommendation
When creating an HA cluster, you are prompted to configure the cluster IP address. We recommend the following setup:
Assign a dedicated IP address
Select a unique static IP address to serve as the cluster IP address, distinct from the physical IP addresses of the NAS devices in the cluster but in the same subnet.
Use the cluster IP address in client configurations
Always configure clients or services (e.g., mapped drives, backup jobs, software connections) to connect to the cluster IP address instead of the physical IP address of either NAS device. This ensures uninterrupted access after a failover.

概念
在高可用性（HA）群集中，群集 IP地址是一个虚拟IP地址，用作客户端连接到群集的主要访问点。
此IP地址代表整个群集，而不是群集内的特定物理设备。当发生故障转移时——即活动节点设备故障，备用节点设备接管成为新的活动节点——群集 IP地址会自动迁移到新的活动节点。这使得客户端可以继续访问服务而无需更改任何网络设置。这种无缝的IP地址交接确保了服务连续性，简化了IT维护和客户端访问。
建议
创建HA 群集时，系统会提示您配置群集 IP地址。我们建议以下设置：
