The image shows an OCI region with two separate VCNs. One VCN contains a workload subnet, while the other VCN contains a Lustre subnet. There are two Lustre client workload instances outside of the VCN, one connects to both subnets, while the other client workload instance connects to the workload subnet. The other client workload instance uses a VNIC to connect to the workload subnet, and a Lustre VNIC to connect to the Lustre subnet. A Lustre file system is outside the VCN and connects to the Lustre subnet.
