Energy Cost Management Solution
The high cost of power requires information and communication technology (ICT) facilities fine tune their operations to minimize energy waste. Dantel provides a suite of WebMon Energy Management solutions to address this critical need.
PUE and DCiE Defined
Currently, two metrics, originally developed by the members of the Green Grid, are being implemented to improve the energy efficiency of existing and new facilities: Power usage effectiveness (PUE) and data center infrastructure efficiency (DCiE).
The PUE is defined as a ratio of the Total Facility Power to the ICT Power and the DCiE is the reciprocal of PUE. Both of these ratios may be used to illustrate energy efficiency. For example, the PUE of 1.6 means that 1.6 units of energy are required to provide 1.0 unit of energy to the ICT equipment. Also, the ratio of 1.6 could be used as multiplier for ICT equipment’s power requirements. For example if a router requires 100 watts and the facility PUE is 1.6, then the utility grid needs to supply 160 watts of power. Similarly a DCiE value of .63 (equivalent to PUE of 1.6) implies the 63% of power is consumed by the ICT equipment.
As a rule of thumb, the higher PUE value indicates degraded energy efficiency and the higher DCiE values demonstrate higher energy efficiency. The key is to express these values in consistent and clear manner when benchmarking.
A critical component in maintaining high efficiency is the concept of concurrent maintenance via active monitoring of the ICT component to the target PUE which is easily handled by Dantel’s WebMon© Edge Green ESP.

Energy Benchmarking
The proactive on-the-go monitoring approach provided by WebMon© is essential to the viability of an effective energy efficiency benchmarking program. Current manual methods of energy audits are expensive and require a lot of time from a dedicated program manager to constantly drive the energy efficiency initiatives.
Dantel has been on the forefront of monitoring of network facilities for almost forty years and is currently providing Green Extra Sensory Power (ESP) solutions that automate the energy efficiency data collection and calculation of such metrics on real-time basis. The setup requires connection to the 208 to 408 VAC RMS power line single or three phase via color coded sensors that can handle 2500 Amps or higher and communicates in Modbus protocol over RS-485 . The first point of access to ICT power occurs at the power distribution unit (PDU). Operational information also is retrieved from various power and environmental control components to complete the full set of real-time data. From this information, the Dantel Green ESP solution provides full trend analysis, timely reports, and when necessary, alarms to alert personnel to action. Alarms may be provisioned based on predetermined PUE, DCiE ,Power Usage, Power Cost and Carbon Footprint analysis. The easy to read dashboard console can also track vital energy metrics such as fuel usage, fuel cost, and carbon footprint on a real-time basis.
The WebMon© E nergy Management solution, part of a full suite of G reen ESP tools offered by Dantel, will ensure success in meeting your ROI objectives on green initiatives for all new and existing facilities.
