2.3. NetworkingΒΆ

Network Hardware

  • 24 or 48 Port TOR Switch
  • NICs - Combination of 1GE and 10GE based on network topology options (per server can be on-board or use PCI-e)
  • Connectivity for each data/control network is through a separate NIC. This simplifies Switch Management however requires more NICs on the server and also more switch ports
  • BMC (Baseboard Management Controller) for lights-out mangement network using IPMI (Intelligent Platform Management Interface)

Network Options

  • Option I: 4x1G Control, 2x10G Data, 48 Port Switch
    • 1 x 1G for lights-out Management
    • 1 x 1G for Admin/PXE boot
    • 1 x 1G for control-plane connectivity
    • 1 x 1G for storage
    • 2 x 10G for data network (redundancy, NIC bonding, High bandwidth testing)
  • Option II: 1x1G Control, 2x 10G Data, 24 Port Switch
    • Connectivity to networks is through VLANs on the Control NIC
    • Data NIC used for VNF traffic and storage traffic segmented through VLANs
  • Option III: 2x1G Control, 2x10G Data, 2x10G Storage, 24 Port Switch
    • Data NIC used for VNF traffic
    • Storage NIC used for control plane and Storage segmented through VLANs (separate host traffic from VNF)
    • 1 x 1G for lights-out mangement
    • 1 x 1G for Admin/PXE boot
    • 2 x 10G for control-plane connectivity/storage
    • 2 x 10G for data network

Documented configuration to include:

  • Subnet, VLANs (may be constrained by existing lab setups or rules)
  • IPs
  • Types of NW - lights-out, public, private, admin, storage
  • May be special NW requirements for performance related projects
  • Default gateways
