Refer to the server requirements and client workstation requirements topics in the Security Center system requirements for the version of Security Center that you are using.
On sites with large cardholder pictures or large volumes of cardholder pictures, the Security Center Directory database should be hosted on a SQL Standard Server or better to ensure that Directory operation is not impaired due to maximum database size limits.
On sites with large volumes of offline events (3 million or more), the proxy service should be installed on a workstation running a 64-bit operation system.
