The following figure provides a high-level overview of the virtual network design that is implemented in the VMware ESXi databases host in the virtual environment. It also shows the mapping between the virtual switches and the physical switches.
Figure 3. Virtual network design in the ESXi virtual databases host
The main components of the design are:
- Public virtual distributed switch (VDS)—We created one VDS, which contains two Distributed Ports Groups. The public port group provides the virtual interfaces for Oracle public traffic for the two Oracle database VMs. The physical uplinks port group is used to add the two 10 GbE physical network ports that are connected to the external 10 GbE ToR switches.
- Standard switch—This switch contains two default 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 VMs. All this management traffic is routed through the 1 GbE physical rNDC or LOM port on the server that is connected to the external management switch.
