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叢集連線是由兩個 NAS 設備組成的高可用性 (HA) 叢集 的管理和服務介面。它是一個虛擬介面，為用戶提供統一的訪問點（IP 地址或主機名）以連接到 叢集 上的服務。在故障發生時，當節點角色切換時，叢集 連接會自動切換到新的活動節點，允許用戶繼續訪問 叢集 服務而無需進行任何網絡配置更改。
創建 HA 叢集 時，您選擇的 叢集 連接的網絡介面將成為主要 叢集 介面。您可以在 High Availability Manager 的「設置」頁面中創建 叢集 後設置次要 叢集 介面。
建議
在創建 叢集 時設置 叢集 連接時，請注意以下要求和考慮事項：
- 在兩個 NAS 裝置上使用相同的網路介面
- 您必須在兩個 NAS 設備上使用相同的網絡介面。
例如，如果您在活動節點設備上使用適配器 1 進行 叢集 連接，則在被動節點設備上也必須使用適配器 1 進行 叢集 連接。 - 叢集 連接的網絡介面不能有 vSwitch 適配器綁定。
- 在同一子網中分配靜態 IP 地址
- 您必須在兩個節點裝置的相同網路介面上分配靜態 IP 地址。
- 確保兩個節點裝置之間的兩個靜態 IP 地址在同一子網中。
- 將兩個 NAS 裝置連線到同一網路交換機
- 叢集 連接應通過同一網絡交換機。這確保了 叢集 網絡的穩定性和可擴展性，同時支持多個設備同時訪問 叢集 服務。
- 確保網路速度和質量
- 叢集 連接的速度和延遲直接影響客戶端的訪問體驗。確保所選的網絡電纜和設備提供最佳性能，避免網絡質量差或過度延遲影響 叢集 服務的穩定性至關重要。
