After you have successfully installed the management server and the management console, you must perform the following activities to install the security virtual appliance (SVA):
Import the security virtual appliance OVA file.
Register the Datacenter Protection Service with NSX Manager.
Deploy the Datacenter Protection Service.
Create a security group and associate Guest VMs to the group.
Create security policies.
Assign security policies to a security group.
After you have installed the security virtual appliance, create a security group and associate the guest virtual machines to the security group. Create security policies and publish them. The published policies can then be applied to a security group.
The SDCS:SA security virtual appliance supports up to 200 guest virtual machines on a single ESX host. If more than 200 guest virtual machines are seen on a single ESX host, the security virtual appliance protects only 200 of them, and the remaining guest virtual machines are unprotected
