Appendix D Connectivity Diagrams

Oracle Private Cloud Appliance network architecture relies on physical high speed Ethernet connectivity. These diagrams depict the to connections to external storage hardware, and compute and management node networking.

D.1 External Ethernet Connections

This section shows the external Ethernet connectivity of an Oracle Private Cloud Appliance using the ports of the Cisco Nexus 9336C-FX2 Switch.

Figure D.1 External Ethernet Connectivity
This figure shows the external Ethernet connections for out-of-band management and for public virtual machine traffic.

D.2 Compute Node Networking

This section shows how Oracle Private Cloud Appliance networking is virtualized and configured on a compute node.

Figure D.2 Compute Node Networking
This figure shows the virtual network connectivity on a compute node.

Diagram Notes

  • vx13040 is the default external network.

  • Internal and External vLAN IDs are specified when creating the network in Oracle VM Manager

  • IP addresses in the 10.0/8 range used here are examples. The actual IP addresses are assigned in the VMs themselves.

  • storage-int is a network for hypervisor access to the storage nodes

  • The virtual networks connecting the network bonds numbered 0-4 are configured by default on every Oracle Private Cloud Appliance. The network connecting all bond6 interfaces is an example of a custom private VM network. The network connecting all bond5 interfaces is an example of a custom public VM network. This type of network requires the configuration of additional I/O ports, which must also be cabled to the next-level data center switches for public access.

D.3 Management Node Networking

Figure D.3 Management Node Networking
This figure shows the virtual network connectivity on a compute node.

Diagram Notes

  • 10.10.10.10/24 is the external address of management node 05

  • 10.10.10.11/24 is the external address of management node 06

  • 10.10.10.12 is the external address of the VIP for management

  • External addresses of mgmt vLAN are specified in the PCA dashboard and are used for access to the PCA Dashboard and OVMM for managing the PCA.

  • storage-int is an underlay network for hypervisor access to the storage nodes
