Network bond types

Based on the VNF requirements, the Telco Blueprints support the following packet acceleration technologies:

  • Open vSwitch Data Plane Development Kit (OVS-DPDK)

  • Single root input/output virtualization (SR-IOV)

Network bond types include the following:

  • Management network bond: A Linux bond is created in 802.3ad mode for the management traffic using a single FLR NIC with two ports.

    The management traffic including OpenStack API Access is provided on the management bond.

  • Data network bond: An OVS/DPDK bond is created in either of the three modes (active-backup, balance-slb, or balance-tcp) as required for data traffic. Both the ports of data NIC are paired and treated as one bond.

Based on the hardware selected, following are the maximum number of supported Data NICs and combinations available:
Table 9: Supported data NICs and combinations
Hardware type Number of Data NICs Combinations Available
HPE Synergy One You can configure either OVS-DPDK or PCI SRIOV
HPE ProLiant HPE DL360 Gen10 Two Following combinations are available:

  • You can configure OVS-DPDK on one data NIC and PCI SRIOV on the other data NIC

  • You can configure PCI SRIOV on both the data NICs

HPE ProLiant HPE DL380 Gen10 and HPE DL385 Gen10 Four You can configure PCI SRIOV on all the four data NICs
HPE ProLiant e910 server blades (EL8000) One Following combinations are available:

  • SRIOV for starter kit or expansion kit

  • OVS-DPDK or SRIOV for expansion kit (computes)
