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.
If the source and target vCenter Server instances use the same SSO domain, the connection is considered local. vSphere Replication uses the SSO service on the local site to authenticate with each vCenter Server in the SSO domain.
If the source and the target vCenter Server instances use different SSO domains, the connection is considered remote. The vSphere Replication Management Server on the source site registers with the Platform Services Controller (PSC) of the remote SSO domain.
You can use vSphere Replication to replicate virtual machines between ESXi hosts that the same vCenter Server manages. In this case, you deploy only one vSphere Replication appliance and do not need to connect the source and target sites.
You can configure a connection on either site on which you have installed a vSphere Replication appliance. If you are using an untrusted certificate, certificate warnings might appear during the process.
You can also set up a connection between two sites while you configure a replication between them.
If you plan to configure a remote connection, obtain the IP address or domain name of the server where the PSC runs. The address appears in the LookupService Address text box on the Configuration tab under VR in the vSphere Replication VAMI on the target site.
- Click vSphere Replication in the Navigator tree of the vSphere Web Client.
- Under vSphere Replication, click the Home tab.
- Click Manage.
- Click Target Sites, and click the Connect to target site icon ().
- Select a target site option.
Connect to a local site
Select this option to connect to a vCenter Server that uses the same SSO domain as the source vCenter Server. If the domain contains no vCenter Server systems to which you can connect, this option is disabled.
For local connections, vSphere Replication uses the SSO service on the local site to authenticate with each vCenter Server in the SSO domain. The list of vCenter Server instances to which you can connect appears at the bottom of the dialog box.
Connect to a remote site
Select this option to connect to a vCenter Server that uses a different SSO domain.
For remote connections, the vSphere Replication Management Server on the source site registers with the PSC of the remote SSO domain. Therefore, you must enter the IP address or host name of the server where the PSC runs, and provide the credentials of a user that has the privilege assigned.
When you log in to the remote SSO domain, a list of all vCenter Server instances to which you can connect appears at the bottom of the dialog box.
- Select the vCenter Server to which you want to connect, and click OK.
