Clusters

Configuration > Networking > Clusters

On this tab you can view all clusters and apply profiles to clusters. There is also a link to the Cluster Profiles tab where you can create cluster profiles. Clusters are created using Site/Cluster Names, and the Site/Cluster name becomes the identifier for a cluster. All appliances with the same Site/Cluster Name are part of the same cluster. Tunnels are not formed between appliances with the same Site/Cluster Name.

  • If you plan to create clusters and you have previously used the Site setting to prevent tunnels from forming between EdgeConnect appliances at different sites, you need to use tunnel exceptions to prevent tunnels from forming between the appliances.

  • Starting with release 9.5, Site/Cluster Names are used to create Locations in HPE SSE.

IMPORTANT: You need to configure a Site/Cluster Name for EdgeHA pairs. The Site/Cluster Name must match precisely for each appliance in the pair.

IMPORTANT: Starting with release 9.5, Site Names are called Site/Cluster Names.

You can apply cluster profiles to clusters. Cluster profiles do the following:

  • Orchestrate flow redirection within a cluster.

    For flow redirection guidelines and limitations, the Flows - Active and Recent page, see this topic: TCP Accelerated Flows.

  • Synchronizes user role information between cluster peers.

  • Synchronizes bandwidth availability between two EdgeHA appliances.

For more information on cluster profiles see, Cluster Profiles.

The following table describes the information displayed on the Clusters tab for each cluster.

Field Description
Cluster The name of the cluster.
Appliances The appliances in the cluster.
Cluster Profile The cluster profile that is currently applied to the cluster.
Config Status Indicates whether Orchestrator has fully pushed the cluster profile that contains all of the cluster configuration settings to all of the appliances in the cluster or not (In Sync or Out of Sync). This status does not convey information about reachability between cluster peers. That information is available in the Cluster Config dialog box, which you can access by clicking the information icon for a cluster.
Peer The number of peers in the cluster.
Interface The interface label that is used for inter-cluster synchronization.
User Session Sync Indicates if user session synchronization is enabled or disabled for the cluster.
Flow Redirection Indicates if flow redirection is enabled or disabled for the cluster.
Monitor Click the chart icon to view Flow Redirection stats and charts for the cluster.
Alarms Indicates if there are any cluster-specific alarms. If there are active alarms, you can click the linked alarm information. The Alarms tab opens and is filtered to show only those alarms and the appliances affected by the alarms.

Cluster Config Dialog Box

To view details about a cluster, click the information icon in the table for a cluster. The Cluster Config dialog box opens. It shows configuration details for the cluster profile that is applied to the cluster and reachability status between the peers in the cluster. The following table describes the fields shown on the Cluster Config dialog box.

Field Description
Profile Shows the configuration settings of the cluster profile applied to the cluster.

Name - The name of the cluster profile.

Interface/label - The interface label that is used for inter-cluster synchronization when this cluster profile is applied to a cluster.

Flow redirection - Indicates whether flow redirection is enabled for the cluster or not.

Wait time - This value (in milliseconds) is used in conjunction with flow redirection to control how long the system waits for an update from other cluster peers before redirecting a flow.

User session sync - Indicates if user session synchronization is enabled or disabled for the cluster profile.

Status - Indicates whether Orchestrator has pushed configuration settings in the cluster profile to all of the appliances in the cluster or not.

If there are any active alarms for appliances in the cluster, those are listed. If you click the linked alarm information, the Alarms tab opens and is filtered to show only the active alarms for the cluster and the affected appliances.
Peers Shows the following information about each peer in the cluster:

Appliance - Name of the appliance.

IP - IP address of the appliance.

Interface - Interface label for the appliance.

The reachability status between an appliance and each peer in the cluster (Reachable or Unreachable).

Add an Appliance to a Cluster

To add an appliance to a cluster, you need to assign the cluster name to the appliance. There are multiple ways to do this.

  • You can assign a Site/Cluster name when setting up a new appliance using the Appliance Configuration Wizard (Configuration > Overlays & Security > Discovery > Configuration Wizard).

  • You can assign a Site/Cluster name to a specific appliance by accessing the System Settings for the appliance from either the appliance tree or the System Information tab.

    1. In the appliance tree, locate an appliance and click the menu button, then click System Information. Or, on the System Information tab (Administration > Software > Upgrade > System Information), click the edit icon for an appliance.

      The System Information dialog box opens.

    2. Click System Settings.

    3. To add an appliance to a cluster, in the Site/Cluster name field enter the name of the cluster to add the appliance to.

    4. To remove an appliance from a cluster, in the Site/Cluster name field delete the name of the cluster to remove the appliance from it.

    5. Click Save.

  • You can assign a Site/Cluster name to multiple appliances on the Cluster tab or on the Tunnels tab.

    1. From either the Cluster tab or the Tunnels tab, click Sites/Clusters.

      The Appliance Site/Cluster Info dialog box opens.

    2. To add an appliance to a cluster, find the appliance in the list. Click in the Site/Cluster column and enter the name of the cluster to add the appliance to.

    3. To remove an appliance from a cluster, find the appliance in the list. Then click in the Site/Cluster column and delete the name of the cluster to remove the appliance from it.

    4. Click Apply.

Applying or Removing a Cluster Profile

  1. In the appliance tree, select the appliances to which you want to apply or remove a cluster profile.

  2. Click Apply Cluster Profiles.

    The Apply Cluster Profiles dialog box opens.

  3. Select the profile from the Cluster Profile menu.

  4. To apply the cluster profile to the selected appliances, select the Add check box. To remove the cluster profile from the selected appliances, select the Remove check box.

  5. Click Apply.
