1.3.4. Control rooms
The control room needs to be a safe environment for operating and
supervising the data center. All disciplines critical to the data center
can be monitored by a management station. The management of all
kinds of events must be ensured at all times. Personnel and
equipment must be protected and allowed to perform even under
difficult circumstances.
An early and reliable fire detection system and a clever alarming
concept is the right choice. Especially in the control room integration
into the management system is a wise choice. Depending on the
criticalness of the equipment, an automated extinguishing solution
similar to the server room ‒ to protect people and IT equipment in
the room ‒ is recommendable.
