Virtual Networks/Overlays

  • Problem Being Solved: Hard to extend L2 net domains & migrate workload
    • Suboptimal asset utilization & availability due to physical rack limited cluster scope(s)
      Workload migration is time consuming & complex
  • Open Networking Components:
    • Open SDN Controllers, OVSDB, multiple tunneling protocol options e.g., VxLAN, open provisioning APIs, neutron, etc.
    • Create an open approach to virtual networking/Overlays
    • Terminate endpoints on hypervisors + ToR
    • Integrated tunneled traffic management
  • Benefits: Extend L2 domains & decouple net config policies independent of underlay
    • Business unit self-­‐service delivery
    • Lower OpEx cost
