  • Page 5: Irf Overview

    IRF overview The HP Intelligent Resilient Framework (IRF) technology creates a large IRF fabric from multiple devices to provide data center class availability and scalability. IRF virtualization technology offers processing power, interaction, unified management, and uninterrupted maintenance of multiple devices.

  • Page 6: Network Topologies

    Figure 1 IRF application scenario Network topologies An IRF fabric can use a daisy-chain or ring topology. IRF does not support the full mesh topology. For information about connecting IRF member devices, see "Connecting physical IRF ports." Basic concepts This section uses Figure 2 to describe the basic concepts that you might encounter when you work with IRF.

    Figure 2 Two-chassis IRF fabric implementation schematic diagram In this figure, Device A and Device B form a two-chassis IRF fabric. The fabric has four MPUs (one active and three standbys), and two times the number of interface cards that a single device provides. The IRF fabric manages the physical and software resources of Device A and Device B in a centralized manner.

    For two neighboring devices, their IRF physical links must be bound to IRF-port 1 on one device and to IRF-port 2 on the other. IRF physical port IRF physical ports connect IRF member devices and must be bound to an IRF port. They forward the IRF protocol packets between IRF member devices and the data packets that must travel across IRF member devices.

    To use enhanced IRF, make sure each IRF member has two MPUs. Selecting IRF physical ports You must use Layer 2 Ethernet fiber or copper ports for IRF connection. HP recommends using 10-GE fiber ports for high performance. IRF physical port binding restrictions When you bind IRF physical ports to IRF ports, follow these restrictions and guidelines: Link aggregation member ports cannot be bound to an IRF port.

  • Page 19: Irf Link Redundancy

    For link redundancy and load sharing, bind up to 12 physical ports to one IRF port. Physical ports bound to an IRF port can be located on different cards. • HP recommends using multicard IRF links to avoid a card removal causing an IRF split. • Multichassis link aggregation For high availability, connect a downstream device to each IRF member device, and assign the links to one link aggregation group.

    To exclude a port from the shutdown action that is executed when an IRF fabric transits to the • Recovery state, use the mad exclude interface command. To bring up a port after the IRF fabric transits to the Recovery state, you must use the mad restore command instead of the undo shutdown command.

    Configuring MDCs Overview The Multitenant Device Context (MDC) technology can partition a physical device or an IRF fabric into multiple logical switches called "MDCs." Each MDC uses its own hardware and software resources, runs independently of other MDCs, and provides services for its own customer. Creating, starting, rebooting, or deleting an MDC does not affect any other MDC.
