Your ability to manage the growth of incoming email and web traffic on your network depends on whether you install a single appliance or multiple appliances as a cluster.
For information about the number of appliances that you need for high availability and load balancing your email and web traffic, contact Technical Support.
Caution
You can't share the cluster scanners between a Trellix DLP Network Prevent cluster and a Trellix DLP Network Monitor cluster. So consider the exact number of appliances you need to create a cluster. Once the cluster role is applied to an appliance, the system reboots automatically. Later, to change the cluster role, you must reset the appliance to factory defaults and apply the cluster role you want.
