vSphere Replication uses the replication technologies included in ESXi with the assistance of virtual appliances to replicate virtual machines between primary and secondary sites.

To use vSphere Replication, you must deploy one vSphere Replication appliance at each site. The vSphere Replication appliance is registered with the corresponding vCenter Server instance on each site. For example, on the primary site, the vSphere Replication appliance registers with the vCenter Server instance on the primary site.

The vSphere Replication appliance contains a vSphere Replication server that manages the replication process. To meet the load balancing needs of your environment, you might need to deploy additional vSphere Replication servers at each site. Additional vSphere Replication servers that you deploy are themselves virtual appliances. You must register any additional vSphere Replication servers with the vSphere Replication appliance on the corresponding site.

The vSphere Replication appliance provides a virtual appliance management interface (VAMI). You can use this interface to reconfigure the vSphere Replication database, network settings, public-key certificates, and passwords for the appliances.

Before you can use vSphere Replication with Site Recovery Manager, you must configure the Site Recovery Manager infrastructure.

When installing Site Recovery Manager, make sure that you select the vSphere Replication option. If you did not select the vSphere Replication option when you installed Site Recovery Manager, you can add that option by running the installer again in repair mode.

Pair the Site Recovery Manager Server instances as described in Connect the Protected and Recovery Sites.

The Getting Started page in the vSphere Replication view of the Site Recovery Manager interface provides guidance to ensure that you complete the installation and configuration process correctly.

1

vSphere Replication is distributed as an OVF virtual appliance. You must deploy the appliance at both of the primary and secondary sites.

2

To use vSphere Replication between two sites managed by different vCenter Server instances, you need to configure a connection between the two vSphere Replication appliances.

3

If necessary, you can reconfigure the vSphere Replication appliance settings by using the virtual appliance management interface (VAMI).

4

The vSphere Replication appliance includes a vSphere Replication server. However, you might need to deploy multiple vSphere Replication servers to meet your load balancing needs.

5

If you deploy additional vSphere Replication servers, you must register these servers with the vSphere Replication appliance to enable them as traffic handlers at the recovery site.

6

You uninstall vSphere Replication by unregistering the appliance from vCenter Server and removing it from your environment.

7

If the vSphere Replication appliance virtual machine does not exist because it was deleted, you cannot use the virtual appliance management interface (VAMI) to unregister vSphere Replication from vCenter Server. Instead, you can use the Managed Object Browser (MOB) to delete the vSphere Replication extension.
