If these elements do not already exist in the vmware-dr.xml file, you can add them anywhere in the
<config> section. If you set the <defaultMaxBootAndShutdownOpsPerCluster> value to 24, the next guest
starts booting or shutting down as soon as one of the first batch of 24 has finished, namely VMs 1 to 24
all start together, then VM 25 starts once one of the first batch has finished, VM 26 starts when the
second one of the first batch has finished, and so on.

Settings for Large Site Recovery Manager Environments
To protect a large number of virtual machines, you can modify the default Site Recovery Manager settings to
achieve the best possible recovery times in your environment or to avoid timeouts.
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.
To modify the settings, see “Modify Settings to Run Large Site Recovery Manager Environments,” on
page 147.
