How are liquid-cooled server rooms monitored? A dynamic environment monitoring solution provides the answer.

As large-scale, intensive construction of liquid-cooled data centers accelerates, server rack power density surges sharply, driving up complexity in operational environment management and physical security. Even minor issues such as temperature/humidity fluctuations, fire hazards, unauthorized access, and equipment malfunctions can disrupt stable data center operation, triggering business outages and data security risks. Hence, building a multi-dimensional power & environment monitoring system covering environmental conditions, fire protection and security surveillance — one that enables real-time status perception, centralized management and intelligent early warning — has become a cornerstone for safe, stable data center operation.

Part 1

Three Core Modules of Data Center Power & Environment Monitoring
The monitoring system is built around three dimensions: environment, fire protection and security, with each module fulfilling distinct roles to deliver round-the-clock real-time monitoring against various safety risks.
Environmental Monitoring
Real-time tracking of indoor temperature and humidity distribution to maintain optimal operating conditions for IT hardware and prevent hardware failures caused by environmental volatility.
Fire Early Warning
24/7 detection of smoke concentration and pressure of gas fire suppression systems, enabling millisecond-level early fire detection and real-time status supervision of fire-fighting equipment.
Security Monitoring
Linkage between access control and video surveillance systems to strictly regulate entry authorization and trigger instant alarms for unauthorized intrusions.
