This image illustrates a detailed architecture of the connection between two Oracle Cloud VMware Solution sites in single availability domains in separate regions for disaster recovery

The image shows two identical, side-by-side boxes, displayed in mirror image. One box is labeled Primary Site and contains a box labeled Availability Domain. Within that availability domain is a virtual cloud network (VCN), labeled VCN 1. The second box is labeled Recovery Site and contains a box labeled Availability Domain, which contains a box labeled VCN 2.

These boxes are connected via vSphere Replication through dynamic routing gateways (RPG) on each VCN, with vSphere replication between them. These RPGs are also connected to similar routing tables.The primary site's RPG points, by solid-line arrow, to a routing table at the top of the image while the recovery site's RPG points, by solid-line arrow, to a routing table at the bottom of the image.

The Availability Domain box for each site contains three vertical boxes representing three fault domains, labeled Fault Domain 1, Fault Domain 2, and Fault Domain 3.

The fault domains are grouped into a VCN, which is connected through the DRG to the on-premises SDDC Customer Premises Equipment icon by the aforementioned dotted line representing a FastConnect or a VPN connection.

Within the VCN is a box representing the Oracle VMware Solution. This is connected to the DRG through a box labeled vSphere Replication Appliance. This box connects by solid line upward to a box labeled vCenter, which then connects downward by solid line to a box within the solution labeled Site Recovery Manager. This box is flanked on each side by boxes labeled SQL on one side and the aforementioned vSphere Replication Appliance on the other. Beneath this, arrayed top-to-bottom, labeled:

• VMware NSX-T
• VMware vSAN
• VMware vSphere

Beneath the solution but within the VCN and across all three fault domains are three icons labeled BM, one for each fault domain.
