Power supply, cooling and sensors in one plant view, developed in house.
What is a BMS in a data center?
A building management system (BMS) monitors the infrastructure a data center’s IT depends on: power paths from transformer to rack PDU, UPS, generators, cooling, temperature, humidity, leakage and fire alarm states. It records measurements, raises alarms by priority and keeps a traceable history for the operations team.
Not to be confused with a battery management system, which monitors the cells of a UPS battery.
BMS, BAS, DCIM and EPMS: the differences
| System | Purpose | Data sources | Typical users |
|---|---|---|---|
| BMSBuilding management system | Monitor building services, raise alarms | Power, cooling, climate, leakage, fire alarms | Operations team |
| BASBuilding automation system | Control HVAC and lighting, often called BMS | Controllers, field devices | Building technicians |
| DCIMData center infrastructure management | Plan rack space, power and cooling | Assets, rack PDUs, IT load | Capacity planners |
| EPMSElectrical power monitoring system | Analyse energy and power quality | Meters, protection relays, switchgear | Electrical engineers |
What a data center BMS monitors
- Power path
- Transformers, switchgear, UPS, generators and PDUs; meters for kWh, A, V, PF, THD.
- Cooling
- Cooling unit states, available capacity and power draw.
- Climate
- Rack inlet and outlet temperature, relative humidity, dew point.
- Leakage
- Cable or point sensors in defined zones, tested alarm chain.
- Fire safety
- Zones and states from the existing aspirating smoke detection.

From pilot to acceptance: the project flow
What we need for a BMS pilot
Plant overview, protocols, data-point lists, measurement locations and alarm routes.
Data quality before visualization
Source, unit, interval and plausibility limits for every data point.
Alarm matrix, not notification noise
Thresholds, delays, priorities and escalation routes, agreed with your team.
Acceptance through traceable tests
Supply lost, UPS on battery, cooling fault: the operator approves each test.

Open BMS Demo 2Questions about data center BMS
GDS Datacenter Solutions combines in-house BMS development with electrical engineering and infrastructure services for data centers.
What drives the cost of a BMS project?
Mainly the number of data points and field devices, the interfaces to existing plants and their protocols, the alarm matrix and notification paths, the historian, roles and retention, and the scope of the acceptance tests. We define these together when we scope the pilot.
Can you connect our existing BAS?
Through the interfaces your plant already offers, such as BACnet, Modbus or SNMP: these are project-specific integration options. We start from your protocols and data-point lists and agree each connection in the pilot scope. No plant is connected to the public demo.
Are you tied to one manufacturer?
No, we work across manufacturers. Real field devices are selected for each plant, interface and test requirement, including range, accuracy, calibration and certificates. The device categories on this page are project components, not a released GDS Datacenter Solutions hardware catalogue.
What is the difference between a BMS and DCIM?
A BMS watches the building services: power path, cooling, climate, leakage and fire alarm states, with alarms and history. DCIM manages the IT side: rack space, power and cooling capacity, assets and connections. Many operators link the two; we agree existing DCIM connections for each project.
Where is the data stored, and how is it secured?
In the demo, history stays local in your browser (IndexedDB), and operator names are labels, not authenticated users. A real plant needs an agreed data-point list, tested device connections, secure user roles, central storage and backups; we agree access rights, the historian and retention with your team.
How does alarm history help?
During transformer loss, the team can trace the switch to UPS battery and generator supply. Acknowledgement records receipt, not resolution. Measurement trends support a shared root-cause investigation.
Ready for a BMS that thinks ahead?
Whether new installation or migration: we’ll advise you without obligation and find the right solution for your data center.
