System information

Option Description
Change the timeout period for
reverse replication during reprotect
operations. The default value is
3600.
Enter a new value in the reverseReplicationTimeout text box. Change this
value if you experience timeout errors when vSphere Replication reverses
replication during reprotect operations.
Change the timeout period for
vSphere Replication
synchronization operations. The
default value is 7200.
Enter a new value in the synchronizationTimeout text box. Change this
value if you experience timeout errors when vSphere Replication
synchronizes virtual machines on the recovery site.
Change the default RPO setting for
replications. The default value is
240.
Enter a new value in the vrReplication.timeDefault text box. The default
value is 240 minutes (4 hours). This value is selected when you configure
replications, but you can specify a different RPO in the Configure
Replication wizard when you configure replication for an individual
virtual machine or for a group of virtual machines.

Modify Settings to Run Large Site Recovery Manager Environments
If you use Site Recovery Manager to test or recover a large number of virtual machines, you might need to
modify the default Site Recovery Manager settings to achieve the best possible recovery times in your
environment or to avoid timeouts.
In large environments, Site Recovery Manager might simultaneously power on or power off large numbers
of virtual machines. Simultaneously powering on or powering off large numbers of virtual machines can
create a heavy load on the virtual infrastructure, which might lead to timeouts. You can modify certain
Site Recovery Manager settings to avoid timeouts, either by limiting the number of power on or power off
operations that Site Recovery Manager performs concurrently, or by increasing the timeout periods.
The limits that you set on power on or power off operations depend on how many concurrent power on or
power off operations your infrastructure can handle.
You modify certain options in the Advanced Settings menus in the vSphere Web Client or in the
Site Recovery Manager client plug-in. To modify other settings, you edit the vmware-dr.xml configuration
file on the Site Recovery Manager Server. Always modify settings by using the client menus when an option
exists. If you modify settings, you must make the same modifications on the Site Recovery Manager Server
and vCenter Server instances on both the protected and recovery sites.
For descriptions of the settings that you can change, see “Settings for Large Site Recovery Manager
Environments,” on page 112.
