2 scalable data centre energy management solution EcoMeasure - Scalable Data Centre Energy Management & Efficiency Measurement Solution by Workspace Technology Ltd EcoMeasure is a service which enables data centre and server room managers to accurately measure the performance and energy consumption of any data centre facility. EcoMeasure can be installed in new or retrofitted within existing data centre and server room environments. The system provides data centre managers with direct information on power and energy consumption and accurate benchmarking of energy efficiency. Benefits of EcoMeasure Deployment Metering the total energy used at a site is important, but it does not show how energy consumption is being used across an area or for a specific function e.g. a data centre facility. Without measurement it can be hard to understand why and where energy performance is poor and how to improve it. It is a recommendation of the Carbon Trust* that sub metering of high energy consumption infrastructure is implemented. The installation of a sub-meter within a server room on its own does not help to fully identify the efficiency of the facility. EcoMeasure is a solution which enables I.T and data centre managers to accurately benchmark the Power Usage Effectiveness** (PUE), Data Centre Infrastructure Efficiency** (DCiE) and usage of the server room environment through direct analysis of power and energy consumption. EcoMeasure is invaluable for both government and commercial organisations which need to track costs associated with server room and data centre environments and to demonstrate CO 2 emission savings when investments are made in either infrastructure or technology. * Carbon Trust is a UK Government body which works with business and the public sector to cut carbon emissions and capture the commercial potential of low-carbon technologies. ** Data Centre Infrastructure Efficiency / Power Usage Effectiveness are industry recognized standards for data centre room efficiency measurement introduced by the Green Grid.
3 EcoMeasure Deployment Benefits Assists in reducing energy consumption, minimising environmental and economic impacts associated with excessive energy use Scalable configurations to suit individual data centre and server room topologies what ever the size and complexity of the power distribution Instant confirmation of Data Centre DCiE / PUE efficiency ratings Accurate proof of the effectiveness of any claimed energy efficiency deployments throughout the life of the facility Measurement of energy consumption, critical load trends, power quality and response time of emergency power plant Ensure utility bills are correct Opportunities to improve a server room or data centres operational efficiency Shows how a server room or data centre compares to other internal or competitive facilities.
4 EcoMeasure Efficiency Metrics EcoMeasure provides data centres with an impressive array of power and energy measurements. In addition to traditional measures, the solution will provide data centre managers with PUE and DCiE energy efficiency metrics. Power Usage Effectiveness (PUE) = Total Facility Power I.T Equipment Power and its reciprocal, the DCiE is defined as: Power Usage Effectiveness (PUE) = I.T Equipment Power Total Facility Power I.T Equipment Power This includes the load associated with all of the I.T equipment, such as compute, storage and network equipment, along with supplemental equipment such as KVM switches, monitors, and workstations/laptops used to monitor or control the data centre. Total Facility Power This includes everything that supports the I.T equipment load such as: Total I.T equipment power Power delivery components such as UPS, switch gear, generators, PDU s batteries, and distribution losses external to I.T equipment Cooling systems components such as chillers, computer room air conditioning units, direct expansion air handler (DX) units, pumps, and cooling towers Other misc. loads including lighting, BMS panels etc.
5 Why Does Data Centre Energy Efficiency Matter? Data centre managers may ask, Does it matter what the energy efficiency rating of my room is? Table 1 below demonstrates the answer to this question in financial terms. Table 2 shows the answer in terms of CO 2 emissions. Table 1 Comparison of energy running costs for typical data centre s with different efficiency ratings (10p per KW/hr). Critical Load Kw DCiE 25% PUE 4.0 DCiE 50% PUE 2.0 DCiE 66% PUE 1.5 DCiE 80% PUE 1.25 DCiE 100% PUE ,040 17,520 13,140 10,950 8, ,080 35,040 26,280 21,900 17, ,600 43,800 32,850 27,375 21, ,200 87,600 65,700 54,750 43, , , , ,500 87, , , , , , , , , , , ,051, , , , , ,752, , , , , ,628,000 1,314, , , , ,504,000 1,752,000 1,314,000 1,095, ,000 Rate per KwH 0.1 Table 2 Comparison of CO 2 with different efficiency ratings Critical Load Kw DCiE 25% PUE 4.0 CO 2 Tonnes DCiE 50% PUE 2.0 CO 2 Tonnes DCiE 66% PUE 1.5 CO 2 Tonnes DCiE 80% PUE 1.25 CO 2 Tonnes DCiE 100% PUE 1.0 CO 2 Tonnes , ,786 1,393 1, ,714 1,857 1,393 1, ,571 2,786 2,089 1,741 1, ,286 4,643 3,482 2,902 2, ,928 6,964 5,223 4,353 3, ,571 9,286 6,964 5,804 4,643 Kw to CO 2 Kw Conversion

10 EcoMeasure Integration Services The deployment of EcoMeasure consists of sequenced activities to ensure that full and accurate measurement can be achieved for each server room or data centre environment. Step 1 - Electrical Services Audit The initial step will require site audit to establish measurement points to ensure Total Facility Power and I.T Equipment Power are measured accurately. Total Facility Power is measured at the input power feeds to the data centre. This should represent the total power entering the data centre (for which the utility supplier will charge). The practical measurement point for I.T Equipment Power is the output of the UPS, UPS bypass switch, or critical distribution power boards which support the critical I.T equipment load. Site sketches, photographs and initial recommendations will form the output of this step. Step 2 - EcoMeasure Design Following the initial EcoMeasure audit, Workspace Technology engineers will generate a practical configuration to ensure accurate measurement of Total Facility Power and I.T Equipment Power. The output of this step is a high level electrical schematic with identified measurement points, PowerLogic equipment schedule, wiring configuration and software configuration parameters. Step 3 - EcoMeasure Installation Measurement technology will be deployed within power distribution boards as specified during the audit phase. A range of split and rope based current transducers (CT s) eliminate the need to power down critical power services. Installation services include all metres, control cable, gateway connections, PoE and Ethernet connectivity. The result of this step is a fully installed and wired measurement and analysis solution. Step 4 - Configure and Commission EcoMeasure Software Workspace Technology consultants will provide basic customer configuration and set up of the PowerLogic* ION Enterprise software. Graphs will include DCiE and PUE along individual metre measurements.
11 Data Centre Consultancy Services Workspace Technology s consultants will review the server room/data centre infrastructure and make recommendations for changes or upgrades that will assist in the improvement of DCiE/PUE efficiency figures. The results of a consultancy engagement will make a series of recommendations, which if implemented can help improve PUE/DCiE ratios and reduce total energy consumption. Once the technology is deployed and benchmarked, Workspace Technology s consultants can provide advice on how PUE and DCiE ratios can be further improved delivering long term reductions in energy consumption. A combined approach of EcoMeasure and consultancy services help our clients achieve tangible reductions in their overall carbon emissions.
