VMware Integrated OpenStack 7.3 supports and validates disaster recovery procedure. The disaster recovery procedure is validated with vSphere 7.0 u2 and NSX-T 3.1.1, SRM 8.4, and vSphere Replication 8.4.
For data plane disaster recovery, VMware Integrated OpenStack leverages the SRM and the vSphere Replication for protecting Nova instances, Cinder volumes, and leverages NSX-T for protecting Neutron networks.
For management plane disaster recovery, VIO leverages backup or restore procedure for recovering the VIO manager and the controller nodes in the recovery site.
VMware Integrated OpenStack 7.2 supports Single vCenter and Multiple vCenter mode topologies. In the single vCenter topology, the management cluster and compute clusters are in the same vCenter for both the source and the target site as shown in the illustration.
Figure 1. Single vCenter Mode.
In the multiple vCenter topology, the management cluster is in vCenter1 and all compute clusters are in vCenter2 for the source and the target site as shown in the illustration.
Figure 2. Multiple vCenter Mode.
In
VMware Integrated OpenStack 7.2, the disaster recovery procedure has the following limitations:
The admin must manually configure the SRM and the vSphere Replication, and NSX-T for data plane protection and recovery.
Supports multiple vCenters for management, and multiple vCenters for compute.
Supports multiple compute clusters under multiple vCenters for compute.
Supports one to one mapping between source compute clusters and target compute clusters.
Does not support instances with the SR-IOV and the vGPU devices.
Does not support Cinder volume with the FCD driver.
Does not support tenant VDC.
Does not support OpenStack images.
Does not support replicating instances with the protection group and the test plan. Otherwise, volume attach and volume detach feature can fail.
The same HTTPS connection mode (secure or insecure) from VIO to vCenter should be configured to both source and target sites.
