In the IT industry, data centers are critical facilities for telecom, internet service providers, mobile operators, dual-line carriers, power companies, and government enterprises. They house servers to provide stable IT services for users and employees.
Small data centers: Cover tens of square meters and accommodate 20–30 racks.
Large data centers: Cover tens of thousands of square meters and accommodate thousands of racks and servers.
The equipment includes servers from IBM, HP, SUN, as well as SMS gateways and communication devices. To ensure business continuity, data centers have stringent requirements for temperature, humidity, and ESD (electrostatic discharge). Any deviation may lead to hardware failures or fires, causing significant economic losses and service interruptions.
Traditional data center monitoring faces several issues:
Insufficient manual inspections: Unable to detect environmental anomalies in real-time.
Fragmented systems: Temperature, humidity, water leakage alarms, and access control operate independently, making centralized management difficult.
Delayed alerts: Most alarms rely on local audio-visual signals, lacking remote notifications.
Limited historical data tracking: Difficult to analyze past events for operational improvement.
