The image shows an OCI region with two separate VCNs. One VCN contains a workload subnet, while the other VCN contains a Lustre subnet. A local peering gateway is used to peer the VCNs. A Lustre file system is outside the VCN and connects to the Lustre subnet. There are two Lustre client workload instances outside the VCN. Both instances connect to the workload subnet, but one uses a VNIC.
