Understanding QFabric System Setup in Network Director


The QFabric Setup task allows you to set up these components of a QFabric system:

  • Node aliases—Aliases replace the hardware serial numbers of components, making it easier to identify system devices and simplify configuration tasks.

  • Node groups—Node groups help you combine multiple Node devices into a single virtual entity within the QFabric system to enable redundancy and scalability at the edge of the data center. There are three types of Node groups in a QFabric system:

    • Automatically generated server Node groups—By default, every Node device that joins the QFabric system is placed within an automatically generated server Node group that contains one Node device (the device itself). Server Node groups connect to servers and storage devices.

    • Network Node groups—You can assign up to eight Node devices to a network Node group. When grouped together, the Node devices within a network Node group connect to other routers running routing protocols such as OSPF and BGP.

    • Redundant server Node groups—You can assign two Node devices to a redundant server Node group. When grouped together, you can create link aggregation groups (LAGs) that span the interfaces on both Node devices to provide resiliency and redundancy.

  • Control plane network—The control plane network is an out-of-band Gigabit Ethernet management network that connects all QFabric system components. The EX Series switches and Virtual Chassis that comprise this network are called Control Plane Ethernet (CPE) switches. The control plane network connects the Director group to the management ports of the Node and Interconnect devices.

    In Network Director, you discover the control plane switches or Virtual Chassis as separate devices. Then you use QFabric setup to map the discovered switches or Virtual Chassis to the QFabric to which they are acting as CPE switches.
