Specifications

The following sections offer hypothetical environments to provide some guidelines for organization size
and hardware requirements.
These example provide minimum requirements for hardware. McAfee
recommends you exceed these requirements to improve performance
and allow for growth, wherever possible.
The McAfee ePO server performance is determined by the SQL database, where the McAfee ePO server
data is stored. It is the main workhorse behind the McAfee ePO server application. The three items
that affect SQL performance are CPU, RAM, and disk performance. These three items control the
responsiveness of the McAfee ePO server application, from a SQL perspective. McAfee recommends
you exceed the minimum recommendations wherever possible.
The following table lists the hardware recommend for the various organization sizes.

Small organization example
A small organization ranges from 100 to 5,000 nodes. You can reduce hardware costs by installing the
McAfee ePO server and SQL database on the same physical server for a small organization. This small
organization is easily managed by the McAfee ePO server and offers room for growth. You can also
have multiple McAfee products deployed in the environment like VirusScan Enterprise, Host Intrusion
Prevention, and Endpoint Encryption.
The hardware used for McAfee ePO server and SQL database must be up-to-date hardware with these
minimum requirements:
• Dual processor CPU
• 4 GB of RAM
• 20 GB of free hard drive space
The ePolicy Orchestrator software 4.5 installation is bundled with Microsoft SQL Express for installing
McAfee ePO server in very small environments. Microsoft does not allow the SQL Express database to
exceed 4 GB. The SQL Express database can only be used for testing the McAfee products and can
also be used in production environments with fewer than 500 nodes.
