For security and network performance, we created a dedicated vDS for the Oracle private interconnect traffic. As shown in the following figure, the Oracle private network design is configured with dedicated VLAN networks (VLAN 101 and 102) to separate the interconnect traffic from other network traffic. For high availability and load balance, the design implements multiple distributed port group uplinks and 25 GbE physical network adapter ports that are connected to two separate 25 GbE ToR switches.
We implemented best practices at each level by creating:
