Interconnect Link Aggregation: Single Switch
Interconnect Link Aggregation: Multiswitch
With the single switch solutions presented in the previous slide, a failure at the switch level would bring down the entire interconnect. A better highly available (HA) design would be to implement a redundant switch strategy as illustrated in the slide, with an Inter-Switch Trunk connecting the switches. This is the best practice design for the Oracle Clusterware interconnect. Only Active/Standby mode is supported in this configuration.
