vNIC Teaming Failover

For NIC failover in a non-virtualized environment, when a service group’s uplink ports fail or are disconnected, the switch disables the affected group’s server ports, causing the server to failover to the backup NIC and switch.

However, in a virtualized environment, disabling the affected server ports would disrupt all vNIC pipes on those ports, not just those that have lost their uplinks (see Figure 19).

Switch

To avoid disrupting vNICs that have not lost their uplinks, BLADEOS 6.5 and the Emulex Virtual Fabric Adapter provide vNIC-aware failover. When a vNIC group’s uplink ports fail, the switch cooperates with the affected NIC to prompt failover only on the appropriate vNICs. This allows the vNICs that are not affected by the failure to continue without disruption (see Figure 20 on

page 160).
