    Creating and Managing Node Groups for a QFabric System

    Node groups help you combine multiple QFabric Node devices into a single virtual entity within the QFabric system to enable redundancy and scalability at the edge of the data center.

    To start managing nodes groups:

    1. Click Deploy in the Network Director banner.
    2. Select the fabric to manage in the network view pane.
    3. Click Manage Node Group under Device Management in the Tasks pane.

      The Manage Node Groups page appears.

    This topic describes:

    Managing Node Groups

    Use the Manage Node Groups page to manage existing node groups and to create new ones. The configured node groups are listed in expandable and collapsible groups:

    • Group: NNG—The network node group. Each fabric has only one network node group, so you cannot create another. You can edit the group’s membership.
    • Group: RSNG—Redundant server node groups. You can create new redundant server node groups and edit existing ones.
    • Group: SNG—Server node groups. You can create new server node groups and edit existing ones.

    From the Manage Node Groups page, you can:

    • Create a new node group by clicking Add.
    • Modify an existing node group by selecting it and clicking Edit.
    • Delete a node group by selecting it and clicking Delete.

    Table 1 describes the information provided about node groups on the Manage Node Groups page. This page lists all node groups within the fabric that is selected in the network view.

    Specifying Settings for a Node Group

    Use the Create Node Group page to define the devices in the node group.

    Table 2 describes the settings available on the Create Node Group page.
