VMware Site Recovery Manager (SRM) is deployed in a paired configuration that includes a protected site and a recovery site. The SRM software appliance is deployed at both sites. A vCenter Server instance is required at both the protected and recovery site.
Requirements for SRM installation are:
- Install the same version of vCenter Server, vSphere Replication, and Site Recovery Manager on the protected site and the recovery site.
- Use Fully Qualified Domain Names (FQDNs) rather than IP addresses when installing and configuring Platform Services Controller, vCenter Server, vSphere Replication, and Site Recovery Manager. Make Forward and Reverse DNS records for all the components.
- Use centralized Network Time Protocol (NTP) servers to synchronize the clock settings of the systems on all the components.
- SRM requires a database. It can be installed either with an Embedded Postgres Database or an external database source such as Microsoft SQL Server or Oracle Database.
- Obtain a Windows user account with the appropriate privileges to install and run the SRM service.
- Obtain the vCenter Single Sign-On (SSO) administrator username and password for both the protected site and the recovery site.
