4.5.3.3. Test 3 – Prove Connectivity and Verify NAT Configuration Including Failover
This test is a repeat of Test 1, but both the vCloud Networking and Security Edge Gateway (Edge Gateway) and vApp are made to fail and are then brought online at the recovery site. The following figure illustrates the end result of this test.
Figure 18. Test 3 End Result
The result of this test is consistent with the Test 1 result, even with the added changes of failing over the vApp and Edge Gateway device.
Testing and validation during the production of this example results in a solution that can help simplify the deployment of vCloud Director DR solutions in the absence of stretched Layer 2 networking. Furthermore, this solution is complementary to the solution already defined in the VMware vCloud Director Infrastructure Resiliency Case Study (http://www.vmware.com/files/pdf/techpaper/vcloud-director-infrastructure-resiliency.pdf) and can be implemented with relatively few additions to the existing vCloud DR recovery process.
