QDIO versus iQDIO Guest LAN

As stated earlier, if you build a guest LAN as a test or model environment for deployment using physical hardware components, then the choice of guest LAN type is predicated on your target hardware deployment. Otherwise, here are some things to consider in choosing the guest LAN type:
  • QDIO (OSA-Express Start of changeand Network ExpressEnd of change simulation)
    • IPv4 and IPv6 support
    • If using a virtual switch is a deployment potential
    • Ethernet transport
    • OSA-Express Start of changeand Network ExpressEnd of change test network
    • If using a virtual switch with a link aggregate group is a possibility
    • Port Isolation for the virtual switch
  • iQDIO (HiperSockets simulation)
    • IPv4 and IPv6 support
    • Supports multicast router connections
    • Deploy MTUs larger than 8K
    • HiperSockets test network
