Models for Assigning
Site Recovery Manager
Licenses in a Shared Recovery Site Configuration

If you configure
Site Recovery Manager
to use with a shared recovery site, you can assign licenses individually on the shared recovery site.
You can also share a license between all
Site Recovery Manager Server
instances on the shared recovery site.
In a shared recovery site configuration, you install
Site Recovery Manager
license keys on each of the protected sites to enable recovery.
  • You can install the same license key on the shared recovery site and assign it to the partner
    Site Recovery Manager Server
    instance to enable bidirectional operation, including reprotect.
  • You can use the same license key for both
    Site Recovery Manager Server
    instances in the
    Site Recovery Manager
    pair, in the same way as for a one-to-one configuration.
  • Alternatively, you can install one
    Site Recovery Manager
    license key on the shared recovery site. All
    Site Recovery Manager Server
    instances on the shared recovery site share this license. In this configuration, you must ensure that you have sufficient licenses for the total number of virtual machines that you protect on the shared recovery site, for all protected sites.
Sharing
Site Recovery Manager
Licenses on a Shared Recovery Site
You connect two protected sites to a shared recovery site. You install a single
Site Recovery Manager
license on the shared recovery site.
  • If you protect 20 virtual machines on protected site A, you require a license for 20 virtual machines on protected site A to recover these virtual machines to the shared recovery site.
  • If you protect 10 virtual machines on protected site B, you require a license for 10 virtual machines on protected site B to recover these virtual machines to the shared recovery site.
  • You share a
    Site Recovery Manager
    license for 25 virtual machines between two
    Site Recovery Manager Server
    instances, C and D, on the shared recovery site. The
    Site Recovery Manager Server
    instances on sites A and B connect to
    Site Recovery Manager Server
    instances C and D respectively.
Because you have a license for 25 virtual machines on the shared recovery site, the total number of virtual machines for which you can perform reprotect after a recovery is 25. If you recover all of the virtual machines from sites A and B to the shared recovery site and attempt to perform reprotect, you have sufficient licenses to reprotect only 25 of the 30 virtual machines that you recovered. You can reprotect all 20 of the virtual machines from site A to reverse protection from
Site Recovery Manager Server
C to site A. You can reprotect only 5 of the virtual machines to reverse protection from
Site Recovery Manager Server
D to site B.
In this situation, you can purchase licenses for more virtual machines for the shared recovery site. Alternatively, you can add the license keys from sites A and B to
vCenter Server
on the shared recovery site, and assign the license from site A to
Site Recovery Manager Server
C and the license from site B to
Site Recovery Manager Server
D.
