The following diagram shows a high-level overview of the virtual network design that we implemented in the ESXi host. It also shows the mapping between the virtual switch network and the physical switch network.
Figure 5. Virtual network design in the ESXi host
The virtual network design supports:
- VM and management traffic—The VM network and management traffic uses the default standard virtual switch (vSwitch), which contains two default standard ports groups. The Management Network port group provides the VMkernel port vmk0 to manage the ESXi host from VCSA. The VM Network port group provides the 1 GbE virtual interfaces for in-band management of the database VM. All management traffic is routed through the 1 GbE physical rNDC or LOM port on the ESXi server that is connected to the external 1 GbE management switch virtual or network.
- Public traffic—The Oracle public traffic uses an additional dedicated standard vSwitch to which we assigned two physical 10 GbE uplink ports. For high availability and load balancing, the two 10 GbE uplink ports reside on two separate physical network adapters and are connected to two separate 10 GbE physical network switches. Within this vSwitch, we created a standard port group that provides the virtual network interface for the Oracle public traffic within the database VM.
