vSphere Replication is a replication engine that is part of SRM 5.0 and requires ESXi 5.0 and later, giving an alternative means of protecting and replicating virtual machines between sites. It is entirely managed within the SRM interface after initial deployment and configuration, and integrates with storage array–based replication to provide full coverage of the virtual environment.
The assumption is that there are multiple databases for vSphere Replication already configured for use, one at each site. In this evaluation guide, we will be using Microsoft SQL Server 2008 Express as a database, and using native SQL authentication for access. Workflow covered will be as follows:
1. Deploy vSphere Replication Management Servers (VRMS).
2. Configure VRMS.
When creating a database only use capitols even the username and the password need to be in capitols 
Also use the fully qualified domain name as a database server, don't use IP-addresses. For configuring vCenter information, scroll down and notice the vCenter configuration information that is necessary. It is very important that the vCenter Server Address field is correctly populated. If you have used IP addresses for all site pairing activities, continue to use IP addresses in this location. If your SRM sites were paired with host names or fully qualified domain names, it is important that you do the same at this location as you did when pairing the sites. VRMS requires naming consistency throughout the process in order to function correctly. Enter the vCenter Server Address for the site you are currently using, which should be the protected site (Site A) vCenter. Click on Generate and Install an SSL Certificate after all the information is filled out.

This will register the VRMS with vCenter and connect to the supplied database to run the initial configuration of vSphere Replication.
If VRMS has been successful communicating with vCenter and the database, it will return to the Configuration screen with a green message labeled Successfully saved the startup configuration. This may take a few minutes to return. Wait until a message is generated, whether it is the green success message or an error. If an error message is generated, re-examine both the database and vCenter information carefully and try again.
