Some components in the Site Recovery Manager and vCenter Server installations must be identical on each site. Because the protected and recovery sites are often in different physical locations, some components on the protected site can be of a different type to their counterparts on the recovery site.

Although components can be different on each site, you must use the types and versions of these components that Site Recovery Manager supports. See the Compatibility Matrixes for vCenter Site Recovery Manager 5.8 at https://www.vmware.com/support/srm/srm-compat-matrix-5-8.html for information.

Table 1. Heterogeneity of Site Recovery Manager Components Between Sites

Component

Heterogeneous or Identical Installations

Site Recovery Manager Server

Must be the same version on both sites.

vCenter Server

Must be the same version on both sites. The Site Recovery Manager version must be compatible with the vCenter Server version.

vSphere Replication

Must be the same version on both sites. The vSphere Replication version must be compatible with the Site Recovery Manager version and the vCenter Server version.

Authentication method

Must be the same on both sites. If you use autogenerated certificates to authenticate between the Site Recovery Manager Server instances on each site, you must use autogenerated certificates on both sites. If you use custom certificates that are signed by a certificate authentication service, you must use such certificates on both sites. Similarly, the authentication method that you use between Site Recovery Manager Server and vCenter Server must be the same on both sites. If you use different authentication methods on each site, site pairing fails.

vCenter Server Appliance or standard vCenter Server instance

Can be different on each site. You can run a vCenter Server Appliance on one site and a standard vCenter Server instance on the other site.

Storage arrays for array-based replication

Can be different versions on each site. You can use different versions of the same type of storage array on each site. The Site Recovery Manager Server instance on each site requires the appropriate storage replication adapter (SRA) for each version of storage array for that site. Check SRA compatibility with all versions of your storage arrays to ensure compatibility.

Site Recovery Manager database

Can be different on each site. You can use different versions of the same type of database on each site, or different types of database on each site.

Host operating system of the Site Recovery Manager Server installation

Can be different on each site. You can run different versions of the host operating system and the host operating system can run in different locales on each site.

Host operating system of the vCenter Server installation

Can be different on each site. You can run different versions of the host operating system and the host operating system can run in different locales on each site.

Heterogenous Configurations on the Protected and Recovery Sites

The Site Recovery Manager and vCenter Server installations might be in different countries, with different setups.

  • Site A in Japan:

    • Site Recovery Manager Server runs on Windows Server 2008 in the Japanese locale

    • Site Recovery Manager extends a vCenter Server Appliance instance

    • Site Recovery Manager Server uses the embedded Site Recovery Manager database

  • Site B in the United States:

    • Site Recovery Manager Server runs on Windows Server 2012 in the English locale

    • Site Recovery Manager extends a standard vCenter Server instance that runs on Windows Server 2008 in the English locale

    • Site Recovery Manager Server uses an Oracle Server database
