Monitor energy usage in server cabinets.

REGY automatically calculates the efficiency of server room cabinets. Using efficiency data, you can make calculated changes to the way your server room works. Optimize your infrastructure and save money in the process.

30% of servers are under utilized costing approximately $4000 USD per year in excess cooling and electrical costs.

Benchmark and monitor PUE in real time.

Measuring the power consumed by IT and non-IT power enables operators to benchmark and compare power consumption from a single or distributed deployment through Power Usage Effectiveness or PUE calculations.

Evaluate future cost-saving measures using the initial PUE benchmark. PUE and other server room metrics can be tracked over time to help identify server room issues and opportunities for cost savings.

Automatic PUE calculations.

REGY calculate PUE values using data polled from numerous devices. A real time PUE value can be displayed rack by rack or for an entire server room.

Did you know?
Many SMEs use distributed server room deployments instead of a single server room. Smaller wire closet rooms are less energy efficient with typical PUE values of…

PUE cost savings : Server Room vs Wire Closet

In the study "Improving Energy Efficiency for Server Rooms and Closets" from Berkeley Lab they explain how an IT administrator for a medium sized company has ~10 servers, each consuming 500W. A cost comparison can be drawn between a using a wire closet setup and server room configuration using PUE calculations.

This example assumes the cost of electricity is $0.12 per kilowatt-hour (kWh).

While the servers are using the same amount of energy, the costs associated with powering the room varies based on the PUE efficiency of the cooling and power infrastructure. By consolidating server racks to a central server room location you can better control cooling help to save on operating costs from day one.


Monitoring the power consumed by IT and non-IT infrastructure is a crucial element of an IT deployment.


Create a SNMP and Modbus Virtual Sensor

Monitor Power using REGY Virtual Sensors.

Use REGY Virtual Sensors to integrate and monitor IT power from any MODBUS or SNMP enabled device such as a UPS, CRAC or PDU.

Virtual Sensors can be monitored locally on an REGY Platform or the REGY Pro Server DCIM.

Create SNMP Get, Custom Scripts, MODBUS TCP, PING and Multiple (Boolean) Virtual Sensors.


























Use REGY Graphing to monitor PUE fluctuations over time.
