Configuring for High Availability
The following figure shows how you might combine the use of link aggregations with VNICs to improve network availability in a virtualized environment. The scenario includes the deployment of Oracle Solaris zones.
Figure 2 Combining the Use of Aggregations With VNICs
In the figure, multiple physical datalinks, net0, net2, and net3, are combined into a single link aggregation, aggr0, which is then assigned an IP address.
The aggregation is further used as the underlying link for configured VNICs that are used by two non-global zones.
This particular configuration makes the VNICs highly available because any failures of the underlying physical NICs that occur are automatically handled by the link aggregation layer and are transparent to the zones.
