Two 25 GbE top-of-rack switches provided the networking. For security, performance, and as a best practice, on the two switches, we separated the network traffic by configuring different VLANs for the different network functions. As an example, we configured the management traffic to use VLAN ID 100, Oracle public network to use VLAN ID 101, two Oracle private networks to use VLAN IDs 102 and 103, and the two storage data networks to use VLAN IDs 104 and 105. For performance, we configured jumbo frames on the switch ports used for the Oracle public, private, and storage data traffic.
