DCEM platforms: why data centers need more than just monitoring
Why traditional monitoring is no longer sufficient?
Ten years ago, an average server rack often consumed between 3 and 8 kW. Capacity planning was relatively simple, and energy costs constituted only a limited part of operating expenses.
That picture has changed drastically.
AI clusters, high-performance computing (HPC), and cloud environments are causing rack capacities of 30, 50, or even more than 80 kW to become increasingly common. At the same time, data center operators are under pressure to:
- to reduce energy consumption
- to achieve sustainability goals
- To report accurately on energy usage
- To make optimal use of available capacity
- to postpone costly expansions
Many traditional monitoring systems generate large amounts of data but offer limited insight. It is valuable to know how much power enters a room, but even more valuable to understand which racks consume the most, where capacity is available, and where optimization is possible.
That is where the strength of DCEM lies.
What is DCEM?
DCEM stands for Data Centre Energy Management.
A DCEM platform collects, analyzes, and visualizes energy-related data from various components of the data center infrastructure.
Consider data originating from:
- Intelligent PDUs
- Inline meters
- Energy meters
- Environmental sensors
- Cooling systems
- Building Management Systems (BMS)
- Main meters
The goal of a DCEM platform is not simply to display measured values. The goal is to generate actionable insights that enable operators to make better decisions.
A DCEM platform helps, for example, answer questions such as:
- Which racks are approaching their maximum capacity?
- Where is capital still available?
- Which customers or departments consume the most energy?
- How does energy consumption develop over time?
- Where can efficiency improvements be realized?
- What data is required for sustainability reports?
From DCIM to DCEM
To understand the growth of DCEM, it is important to look at the development of data center management software.
For years, DCIM (Data Centre Infrastructure Management) platforms were the standard. These systems focused primarily on:
- Asset management
- Rack layouts
- Equipment registration
- Work processes
- Infrastructure documentation
Although these functionalities are still important, a new need emerged: gaining control over energy consumption and energy efficiency.
Whereas DCIM focuses primarily on infrastructure management, DCEM focuses on energy management.
| Traditional DCIM | Modern DCEM |
|---|---|
| Asset management | Energy management |
| Equipment registration | Capacity optimization |
| Statistical data | Real-time insights |
| Documentation | Analysis and reporting |
| Infrastructure-oriented | Sustainability-oriented |
DCEM does not completely replace DCIM. In many cases, both systems complement each other.
Why AI accelerates the adoption of DCEM
Artificial intelligence has a huge impact on the energy infrastructure of data centers.
Whereas a traditional rack used to consume a few kilowatts, modern AI platforms such as NVIDIA H100, B200, and GB200 systems require significantly more power.
This brings new challenges:
- Extremely high power densities
- More complex capacity planning
- Higher cooling requirements
- Faster changing taxes
- Higher energy costs
An incorrect estimate of available capacity can lead to delays, costly expansions, or inefficient use of existing infrastructure.
To effectively manage AI environments, detailed insight into energy consumption is essential. DCEM platforms provide exactly that information.
Five problems that DCEM platforms solve
1. Better capacity planning
One of the biggest challenges in a data center is determining the actually available capacity.
Many organizations still work with theoretical calculations or historical data. In practice, actual energy consumption often turns out to deviate significantly from these assumptions.
DCEM platforms provide real-time insight into:
- Available rack capacity
- Taxes per group
- Capacity per power feed
- Historical trends
This allows new systems to be installed with greater certainty without unnecessary safety margins.
2. Insight into energy costs
Energy is one of the largest operational costs for many data centers.
Without detailed measurements, it is difficult to determine where energy is actually consumed.
DCEM platforms make it possible to:
- To analyze consumption per rack
- to compare customers or departments
- To identify inefficient equipment
- To monitor trends in energy consumption
Greater insight often leads directly to savings opportunities.
3. Sustainability and compliance reporting
Data centers are increasingly facing reporting obligations regarding sustainability and energy efficiency.
Examples include:
- CSRD
- ESG reporting
- ISO 50001
- European energy efficiency guidelines
Manually collecting this data takes a lot of time and increases the risk of errors.
DCEM platforms automate the collection and reporting of energy data, making reporting faster, simpler, and more reliable.
4. Faster response to incidents
Problems rarely arise without warning.
Often, there are visible signs beforehand, such as:
- Increasing current
- Impending overload
- Abnormal energy consumption
- Temperature increases
DCEM platforms can automatically alert operators so that action can be taken before system availability is compromised.
5. Better utilization of existing infrastructure
Many data centers operate with generous safety margins to avoid risks.
Although that is understandable, this often leads to unused capacity.
Through accurate measurements, operators can utilize existing infrastructure more efficiently without compromising reliability.
In some cases, this can delay a costly expansion for months or even years.
The future of DCEM
The next generation of DCEM platforms goes beyond monitoring and reporting.
New future developments include:
Predictive capacity analysis
Based on historical data and growth patterns, the software will predict where future capacity problems will arise.
AI-driven analyses
Machine learning can automatically detect anomalies, inefficiencies, and potential malfunctions.
Automated sustainability reporting
Reports are generated directly based on real-time energy data.
Digital twins
Digital representations of the data center make it possible to virtually test changes before they are implemented.
Integration of energy and cooling
More and more systems combine energy and cooling data for a complete picture of the data center's performance.
What requirements must a DCEM platform meet?
Not all DCEM solutions offer the same functionality.
The following aspects are important when selecting a platform:
Real-time data
Up-to-date information is essential for effective capacity management.
Open integrations
Support for protocols such as:
- SNMP
- REST API
- MODBUS/TCP
makes integration with existing systems easier.
Scalability
The platform must be able to grow with the data center.
Reporting functions
Clear dashboards, trend analyses, and export options simplify management.
Multi-vendor support
Most data centers contain equipment from multiple vendors. A platform should therefore not be dependent on a single brand.
Security
Now that monitoring systems are increasingly connected to corporate networks, cybersecurity is becoming an increasingly important selection criterion.
Energy management is becoming a strategic priority
The role of energy in the data center is changing.
Whereas energy management used to be primarily an operational task, it is increasingly becoming a strategic issue that impacts capacity, sustainability, costs, and growth.
The combination of AI workloads, higher rack densities, stricter regulations, and rising energy costs makes it clear that traditional monitoring alone is no longer sufficient.
Data center operators need insight, context, and actionable information.
That is precisely why DCEM platforms are rapidly gaining importance.
The future of data center management is not about collecting more data, but about utilizing that data more intelligently. Organizations that succeed in this can better utilize their capacity, optimize their energy consumption, and be better prepared for the challenges of tomorrow.
And therein lies the strength of modern DCEM platforms.
