Use this tab to configure following advanced options for a subclient:
Number of Data Readers
Specify the number of simultaneous backup data streams allowed for the subclient.
Select VM Client Group
Select an existing client computer group from the list to add all instances for the subclient to the group. When a group is assigned for a subclient, the assignment is performed during instance discovery, and replaces any previous instance assignments for the group.
Proxies
By default, the backup of any instance is performed by one of the proxies assigned to the virtualization client. The first proxy in the list (the coordinator proxy) distributes virtual machines across the available proxies for the virtualization client.
You can add, remove, or change the sequence of proxies to be used for backups of instances in the subclient. Proxies specified at the subclient level override the proxy list for the virtualization client instance.
Add
Click Add to select proxies to assign to the subclient.
Remove
Select a proxy and click Remove to remove the proxy from the list of assigned proxies.
or 
Select a proxy and click the up arrow or down arrow to change the order of the proxies.
Clients / Client Groups
Displays the list of clients or client groups that are assigned as proxies for the subclient.
Exclude from SLA and Strike Counts
When this option is selected, the subclient is excluded from the SLA (Service Level Agreement) calculation and the Client Strike calculation for the Worldwide Dashboard, CommCell Dashboard, SLA Report, and Client Strike Count Report. When this option is cleared, the subclient is included in these calculations.
