About this release This document contains important information about the current release. We recommend that you read the whole document. Important: The features in this release of McAfee Enterprise Security Manager are ideal for large installations that include staging environments. Because the linear scaling and replication features provide different performance enhancements, best practice includes installing this version in a staging environment. Run it with an emphasis on scaling for 2-3 weeks and then run it in a replication configuration for 2-3 weeks. This will give you performance indicators that you can use to design the optimal scaling/replication setup for the production environment.
