In a data center with an indoor height of 6.5 meters, Inergen is a recommended fire suppression system due to its effectiveness in a sealed environment and its ability to provide a safe atmosphere for personnel. Inergen is a clean agent made of naturally occurring gases (nitrogen, argon, and carbon dioxide) that works by reducing the oxygen level in the protected area to a point where it can extinguish fire without harming electronic equipment or endangering individuals.

This system is particularly useful in environments like data centers, where equipment and irreplaceable data can be severely damaged by water or chemical fire suppression methods. Inergen is designed to be safe for occupants, allowing for a brief evacuation time, as it does not produce harmful residues or toxins, making it suitable for high-value electronic environments with restricted air flow.

The other options, while they are effective fire suppression agents in certain circumstances, may not be as suitable for specific environmental conditions found in data centers with the stated height. For example, FM200 and Novec-1230 are chemical agents that may also be effective but often require different design considerations for their application, particularly in taller spaces where airflow and agent distribution need to be managed carefully.
