What to do next
If you still experience timeouts after increasing the RemoteManager timeout value, experiment with
progressively longer timeout settings. Do not increase the timeout period excessively. Setting the timeout to
an unrealistically long period can hide other problems, for example problems related to communication
between Site Recovery Manager Server and vCenter Server or other services that Site Recovery Manager
requires.
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.
Example: 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.
n
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.
n
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.
n
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.
