Cluster Management

Load Balancing

Use this page to specify the load-balancing requirements for the appliance when acting as part of a
cluster.
The content of this page can vary. Depending on the cluster mode, some of the options are not available.
When configuring a group of appliances or McAfee Content Security Blade Servers, the current master
uses a "least used" algorithm to assign connections to the appliances or blades configured to scan
traffic. The scanning appliance or blade that is currently showing the least number of connections, at
that moment in time, is assigned the next connection.
For a cluster of appliances:
• If you have only a master and a failover appliance, with both configured to scan traffic, the master
will send most connections to the failover appliance for scanning.
• If you have scanning appliances, and scanning enabled on the master and failover, then the
scanning appliances will receive the most traffic to scan, then the failover, with the master
receiving the least. If you have more than three appliances in a cluster, McAfee recommends that
you do not enable scanning on the master appliance.
You cannot configure the master or the failover blades of the McAfee Content Security Blade Server to
scan traffic.
McAfee recommends that when using your appliance in a cluster
environment, you use McAfee Quarantine Manager to quarantine Email
messages.
