This article applies to upgraded vSphere Replication appliances that use an embedded database. Use the table below to determine whether your vSphere Replication deployment requires additional configuration to enable the support of up to 4000 replications per vSphere Replication appliance.

Please note that versions prior to vSphere Replication 8.4 only support a maximum of 2000 replications

Note: In addition to configuring the upgraded appliance, the maximum number of replications that a vSphere Replication Management Server can support depends on a number of factors in your environment, like bandwidth, change rate, compressibility, RPO, and others. See Requirements to the Environment for the Support of Up To 4000 Replications (KB 2107869).

The purpose of this article is to explain how to modify the event maximum age in the vSphere Replication appliance.

1. Change the value for event maximum age to 3 hours.
   If you plan to replicate more than 500 virtual machines, you must change the default value for event maximum age at the vSphere Replication appliance.
   1. In the remote console session to the vSphere Replication appliance, open the /opt/vmware/hms/conf/hms-configuration.xml file for editing.
       
   2. Change the value for event maximum age to the following:
      <hms-eventlog-maxage>10800</hms-eventlog-maxage>
       
   3. Restart the HMS service by running the following command:
      # service hms restart
       
   4. Stop VCTA service.

      For vSphere Replication 8.1 and earlier versions, run this command:

# service vmware-vcd stop

# service vcta stop
