THE LEGR

A fast-evolvingmarketThe growing of the digital infrastructures’ marketis powered by the ever-increasing data flows inbuildings. Driven by the Internet of Things (IoT),the cloud and the increased focus on security andenergy efficiency topics within standards, the roleof data centers is quickly changing.

The IoT’s impact on the datalandscapeIn 2014, there were about 14 billion devicesconnected worldwide. By 2020, there willbe 50 billion (source: Cisco). The Internetof Things affects not only the design andimplementation of data centers but also theiravailability and scalability.The IoT requires that data is handled locally,for example using micro data centers. Thiswill mean a boost for the micro data centermarket, globally: from 1.7 billion dollars in2015 to 6.3 billion dollars by 2020.

From cloud to colocationAnother trend that affects the data centermarket is the adoption of the cloud. Cloudproviders are going to move up in the supplychain and be empowered to implement datacenter infrastructure that best suits theirvery own needs.The strong increase in the demand forcolocation comes from the desire ofcompanies to reduce IT costs. By opting forcolocation data centers, they choose highquality technology, scalability and availability,while managing the IT environmentthemselves.

New European guidelinesUnder the influence of the cloud, there is agrowing demand for data center security andsafety solutions.That demand is amplified by an increasedfocus on security topics within the EuropeanEN 50600 data center standard: the renewedsecurity approach combines optimumsecurity with an accessible workingenvironment.

Data centers are sensitive areas which consume a huge amount ofenergy and have changing requirements. They house servers containinglarge amounts of data. Ensuring they are flexible, efficient and reliablethus means implementing a durable infrastructure which provides highperformance under all circumstances.There are four main objectives for providing an optimum response to thespecific issues and requirements of data centers.

Optimize energy efficiencyData centers consume a great deal ofenergy. The aim will therefore be toreduce their carbon footprint. How?By improving the PUE (Power UsageEffectiveness). This is an indicatorwhich defines the energy efficiency ofa data center by calculating the ratioof the total energy consumed by thedata center as a whole to that actuallyconsumed by the IT systems which thedata center operates.→ DISCOVER OUR SOLUTIONS IN THE« EFFICIENCY » SECTION

Ensure continuity of serviceMaintaining an electrical and digitalsupply throughout the year as well ascooling the servers ensures availabilityof reliable energy. There are severalavailability levels. Depending on the levelof availability required by the data centerowner for all the equipment and infra-structures, the building will be assigneda Tier, from 1 to 4, which guarantees acertain continuity of supply and service.→ DISCOVER OUR SOLUTIONS IN THE« AVAILABILITY » SECTION

Incorporate the need forscalabilityIt may be necessary to add a UPS or acooling module, server or switch - a datacenter has to be able to change, and theinfrastructures must do the same in or-der to support the durability of the datacenter. This involves in particular usingsolutions which combine optimization ofspace and modularity.→ DISCOVER OUR SOLUTIONS IN THE« SCALABILITY » SECTION

Ensure the safety and securityof equipment and dataA data center hosts strategic data thatare essential for the operation of thecompanies they belong to. It is thereforeabsolutely necessary to protect equip-ment against any intrusions or internal/external events, and to ensure the safetyof the people who work on-site.→ DISCOVER OUR SOLUTIONS IN THE« SAFETY AND SECURITY » SECTION

ENERGY-INTENSIVE BUILDINGSFor example:- a typical data center consumes 10 to 100times more energy per m² than a standardoffice building- the consumption of a 10,000 m² data centeris the same as that of a town with 50,000inhabitants- over 10 years, the operating cost of a datacenter is the same as its installation cost- the electricity bill represents 10 to 15% ofthe operating costThe building infrastructure currentlyrepresents close to half of the total energyconsumption.

Context&issues

AN INCREASINGLY LARGE ECOLOGICALFOOTPRINTThe environmental footprint of data centerscontinues to increase: over the 10 comingyears, it is estimated that there will be30 times more data (including 90% unstruc-tured data) and 1000 times more servers.At this pace, energy needs could doublewithin five years. It is therefore essential toreduce the carbon footprint of data centersand improve their energy efficiency, in orderto reduce consumption and costs.

Legrand Group’sresponse

OBJECTIVE: REDUCE THE PUEThe PUE (Power Usage Effectiveness) is anindicator for measuring the energy efficien-cy of a data center by working out the ratioof the total consumption of the data centerto that of the computer and telecoms (IT)equipment. The ISO/IEC 30134-2:2016“Information technology -- Data centres-- Key performance indicators -- Part 2:Power usage effectiveness (PUE)” standarddefines several PUE categories:

Basic PUE (Category 1)This measurement stipulates the conver-sion of all measurements into kilowatt-hour(kWh). It is a precise method includingenergy sources other than mains electricity.PUE1 is calculated over a 12-month period.

Intermediate PUE (Category 2)This measurement includes the category1 requirements. However the IT consump-tion is measured at the PDUs (PowerDistribution Units). A clear distinction istherefore made between the infrastructureand the IT equipment and it is easier tomeasure a pPUE (partial PUE).

Advanced PUE (Category 3)This measurement includes the category2 requirements. It refines them by requir-ing the IT consumption to be measured atdevice level. A data center with optimum ef-ficiency will be PUE 1, whereas the averageglobal PUE of a data center is between 1.8and 1.89 (source: Uptime Institute survey2012). Reducing this is therefore a priorityin order to ensure that the infrastructureprovides ever-higher performance.

NOTEISO/IEC standardised additionalindicators to refine the assessmentof the ecological footprint of a datacenter:- The Renewable Energy Factorwas standardised as the ISO/IEC30134-3:2016 Information technology-- Data centres -- Key performanceindicators -- Part 3: Renewableenergy factor (REF)- The Energy Reuse Factor (ERF):this measure of the amount of energyreused outside the data center is in

the process of being standardised- The Carbon Usage Effectiveness(CUE): this extrapolates a greenhousegas emission volume based on theelectricity consumption of the datacenter- The Water Usage Effectiveness(WUE): it measures the amount ofwater used in the data center.

These last two KPI are on the list forfuture standardization.

Data centers are increasingly using energyefficient cooling techniques such as freecooling. We offer a variety of active coolingproducts both DX and H2O:

Separation of hot and cold airflowsBy separating hot and cold air using aislecontainment solutions, this step leads toan optimum reduction of air leakage andincreases the energy efficiency.

Optimization of the cold air circuitThough the airflow optimization in the rackis often not fully or effectively implemented,it is the next step in energy-efficient datacenters. Objective: minimize the air leakage.Airflow optimization is also important for theproper functioning of the server, network andstorage equipment, for temperature stabilityand for the general reliability of a data center.

Optimizethe cooling solutionsThe cooling systems are the main item of consumption in a data center.To reduce the energy consumption, the consumption by the server coolingsystems must above all be reduced.This involves:- an optimized design of the white room (IT room, the heart of the data center)- selecting the right cooling solutions

Thanks to its worldwidenetwork of partners,Legrand supports youduring the decisive stagesof your project:

- selection of the rightsolutions when definingthe white room’s design

- sizing of the coolingsolution in relation to thepower of the servers

THE LEGRAND ADVANTA

“MINKELS’ FREE STANDINGCORRIDOR”The Free Standing Corridor is a fully self-supporting aisle containment systemthanks to which closed-off aisles can becreated independently from the IT racks,which is not usual in the data centermarket. Its modular design consistsof a self-supporting construction, wallpanels, roof panels and sliding doors.Immediately after implementation, theenergy efficiency reached is the sameas that of a regular aisle containmentsystem supported by IT racks. The FreeStanding Corridor offers corporate andcommercial data centers a cost-efficient“pay-as-you-grow” solution in order tocreate energy efficiency at low initialinvestments (CAPEX).



SEPARATION OF HOT AND COLD AIRIn addition to simply separating the hot/coldair flows by creating dedicated aisles, the coldaisle containment enables the aisles to becontained for optimized cooling.The hot air and cold air are separated whenthe room is designed, using roofs, panels anddoors (at the entrance and exit). This veryeffectively reduces the energy consumptionof the air conditioning units (visible reduc-tion via the air conditioning unit consumptionreports). The cold aisle containment providesan average of 30% energy savings.

OPTIMIZATION OF THE COLD AIR CIRCUITCooling the room

This is done using CRAC (Computer RoomAir Conditioning) units.Traditionally, the cold air is sent into the falsefloor at a slightly higher pressure and exitsvia perforated tiles in the contained coldaisle. The hot air is evacuated in the hot aisleand reprocessed by the unit.

Principle of the room cooling system

Class A1:typically a data center with tightly controlled environmental parameters (dew point,temperature, and relative humidity) and mission critical operations.Classes A2/A3/A4:typically an information technology space or office or lab environment with somecontrol of environmental parameters (dew point, temperature, and relative humidity).

OPTIMIZATION OF THE COLD AIR CIRCUIT(continued)

Row-based cooling solutionsThese cooling solutions integrated in theaisle (in or between the racks) reduce thecomplexity of the installation and providecooling as close as possible to the server.Particularly suitable for high density solu-tions or rooms without false floors, thesesolutions optimize the air flow so that it isas short as possible, which results in lowerlosses.

Example: the H20 cooling systemCommonly called a chilled water system, ituses water for exchanging thermal energybetween the secondary system and theprimary outdoor system. When the systemis running outside a water/glycol mixture isused as a coolant to prevent freezing. Thesystem can be designed as a single loopsystem avoiding an extra heat exchanger andtherefore maximizing the capability of freecooling. The water infrastructure is com-monly managed as a circuit for a whole roomor is part of a complete building.

The objective is to reduce power losses so as to increase the efficiency of theelectrical infrastructure. Power losses connected with energy conversion andUPSs currently represent around 10% of the total energy consumption of adata center, where the cooling alone represents 32%.Given the efforts made with regard to cooling, particularly through designsenabling the use of free cooling, these power losses will account for a largepart of the data center’s energy bill.

In order to increase the efficiency of theelectrical infrastructure, it is thereforenecessary to look into solutions that willreduce this percentage, in particular viathe power supply and distribution systems.Various products, providing high perfor-mance installations, improve the qualityof the energy and limit power losses, thusreducing the environmental footprint:

NOTEThe reduction of power losses must beworked at on a daily basis, via carefulmanagement of the energy requirements.Those responsible for operating a datacenter must therefore pay attention to theflow and quality of the incoming energy inorder to adapt the power demand to theactual requirements of the data center andensure optimum use of the power received.As the various power devices operateefficiently at low load conditions (atransformer used at 10% of its capacityis 3 times less efficient than at 60% ofit capacity, likewise for inverters andair conditioning units.), their energymanagement will be optimized and powerlosses limited.

In fact, if the efficiency of the UPS isincreased, it will give off less heat, which willreduce cooling and consumption losses.Legrand offers UPS solutions that can achieveefficiency levels of up to 96% mode Online(VFI - Voltage Frequency Independent doubleconversion).

EFFICIENCY LEVELS UP TO 96%*

WITH LEGRAND’S UPS!

NOTEThe power of a UPS is usually de-scribed in kVA, but a data center issized in kW because it is necessaryto know the actual active power to besupplied.The power factor of the UPS, i.e. theratio between the active power (in W)and the apparent power (in VA), istherefore a very important indicatorof its performance. It often reaches0.8, while high performance UPS havea power factor of 0.9 or even 1 (whichis the case with Legrand UPS). Thismeans that when 80 kW is required,an 80 kVA UPS with a power factor of1 will be adequate, whereas a UPSwith a power factor of 0.8 at the outputmust be sized at 100 kVA.The electrical infrastructure (rating ofthe circuit breakers) will therefore bebetter sized.

REAL WORLD RESULTSWhen Cisco sought to reduce itsenergy consumption and costs, itslabs were an obvious target as theyaccounted for 60% of the company’stotal power usage, yet occupiedonly about 10% of its real-estatespace. The largest savings camefrom deploying smart PDUs in allnew labs and in major lab retrofits,as well as in existing labs. These

PDUs were compatible with Cisco’sEnergyWise infrastructure, whichCisco said removed barriers toadoption. The amount of powerthat the smart PDUs have savedvaries from 5 to 60%, dependingon the lab. At least $ 8.6M in annualelectricity bill savings is beingachieved according to in-depthcalculations by Cisco!

GREEN T.HE HV/LV TRANSFORMERSThese provide high energy efficiency anda lower environmental footprint (fewerpollutants).An average of 3 times fewer losses is ob-served with these high efficiency transform-ers than with a standard transformer.The Legrand Green T.HE offer gives youaccess to classes AoBk, AoAk and AAoAksolutions.

PX® INTELLIGENT PDUsRaritan’s offer comprises 230V and 415Vmodels, in hundreds of different configura-tions, including per socket monitoring thathelp to improve power usage effectiveness ofdata centers. Remote and “at-the-rack” datacollection of current (amps), voltage, power(kVA, kW), and energy consumption (kWh)allows you to:- benchmark entire racks and individual ITequipment as to identify inefficient IT devicesand ghost servers,- identify when more power is going to a rackthan needed and deploy “stranded power”elsewhere,- drive energy-efficient behavior and supportsustainability initiatives.Power data obtained from PDUs can help youcalculate PUE at a granular level, allowingfor Category 3 PUE reporting. IntelligentPDUs send power-usage data over the net-work to a DCIM solution such as Power IQ®

to automatically calculate PUE. Total powerused in each rack can be compared to thebuilding’s overall power usage to create thefoundation for PUE calculation.

OVERALL CONSUMPTION OF A RACK(FOR PUE CATEGORY 2) AND/OR A SERVER(FOR PUE CATEGORY 3)This involves measuring the energy con-sumed by the IT systems. This is done usingPower Distribution Units (PDU), intelligentrack transfer switches and monitoringsolutions.

Power Distribution UnitsRack PDU metering allows data center man-agers to monitor power in real-time to avoiddowntime brought on by overloaded circuits,and to efficiently utilize power resources.Legrand’s PDUs are equipped with an am-meter. The 1-U PDU ammeter can be rotated90° to ensure easy reading regardless ofmounting position (horizontal or vertical).Raritan’s PX Intelligent PDUs are fittedwith monitoring features that detect hiddenproblems in your power chain, test for trueredundancy and implement more efficientload balancing with detailed measurementsfrom each server’s power supply.

NOTEFor a PUE category 2, it is possible to:- locate the measurement remotelyfrom a PDU for the consumption of arack at its upstream protection device,thus enabling a basic PDU to be used.- integrate measurement in the tap-offboxes connected to the prefabricatedbusbar trunking .

Hybrid Transfer SwitchesRaritan’s hybrid rack transfer switch systemis the first in the world to offer inlet, outlet,and branch circuit level power meteringas well as outlet level switching for betterremote power control!

Branch Circuit Monitor (BCM)Raritan’s Branch Circuit Monitor series pro-vides data center managers with real-timeand historical views of electrical capacityand power usage at the panelboard, floorPDU, RPP or overhead busway.

DCIM monitoringAssociated with PX and PXE PDUs, Raritan’sPower IQ® DCIM Monitoring Software en-ables you to closely monitor and efficientlyutilize your existing data center powerinfrastructure. A configurable dashboardprovides vendor agnostic views of powercapacity, environmental health, and energyconsumption.

Electrical distribution racksDiscover our increased safety solutions onpage 37!

PERFORMANCE AND RELIABILITYOF SOLUTIONSEnsuring a data center is constantly avail-able involves selecting solutions that ensurecorrect operation over time. For this, theLegrand Group develops and designs itshigh performance products and systemswith safety margins well beyond those in thestandards, to ensure they operate correctlyirrespective of the environment in which thesystems are installed and used.

Dry type transformerThis is one of the most reliable products inthe electrical infrastructure:- once it has been commissioned, it requiresvery little maintenance in comparison withan oil-immersed transformer, which has tobe inspected regularly- it does not contain any moving parts, or anyinsulating fluids: there is therefore no risk ofleaks or any need for regular maintenance.



Capacitor banksThe design of these is completely dry. Theyincorporate capacitors:- designed to last and to withstand thestresses of the electricity supplies:overvoltages, harmonic pollution, etc.- with a tolerance significantly higher than inthe standards (U max = 1.18 Un constantly)The service life of the compensation systemis therefore increased.

Structured cabling systemsWhen describing the performance of a struc-tured cabling system, independently of thetechnology used for the conductor whetherit is copper or optical fiber, the transmissionspeed is the reference point.LCS³, the new Legrand structured cablingsystem, ensures high performance andreliability for the installation via zero faultsolutions and routing systems that are idealfor copper and optical fiber cables.

STANDARDSThe reference standards for avail-ability mainly concern structuredcabling. They include the projectand the installation of the systemas a whole, and also the technicalcharacteristics of each compo-nent. Although the standards arestructured differently for eachcontinent, they all cover all theimportant topics and contain inparticular the requirements forperformance, safety and confor-mity of installations.

ZERO FAULT SYSTEMThe innovative Legrand LCS³ offer provides you with:• 25 Gbps and 40 Gbps BASE-T Ethernet solutionswith the copper system.• 40 Gbps and 100 Gbps Ethernet solutions withthe optical fiber system.To ensure the 40/100 Gbps and Fiber Channelprotocols are supported, hence opt for LCS³ highspeed optical fiber solutions, among which ournewest MTP connectors and cassettes! They makefor a perfect connection in just a few seconds, giv-ing a link providing excellent performance levels,from the patch panel through to the workstation!These solutions can be used to create wiringarchitectures for the LAN and SAN infrastructuresof data centers with OM3 and OM4 performancelevels, in multimode and OS1/OS2 in single-mode.As for LCS3 Cat. 8 copper solutions, they provideperformance levels meeting the “ISO/IEC 11801standards - third edition” requirements.All the LCS3 components are tested individually atthe end of production and their excellent perfor-mance levels over short links (less than 15 m)ensure availability of the bandwidth at the highestfrequencies. As for the Legrand RJ 45 and opticalfiber connectors, their design ensures they complywith the installation regulations: correct installa-tion is thus assured!

Constant access to a high performance network

NOTEOptical fiber

This is a transmission medium that enables a largerbandwidth to be used than copper cables. Optical fibercables have major advantages over copper cables:total immunity to electromagnetic interference, hightransmission capacity, low attenuation, much smallercable sizes (10 times smaller than a copper cable)…

PoE certificationWith PoE technology, devices (Wi-Fi access points,cameras, etc.) can be supplied directly with the Ethernetdata cable. In a single cable one has the passage of dataand voltage to supply the peripherals.There are three types of PoE in relation to the powersupplied:- PoE standard IEEE 802.3af (2003),- PoE + standard IEEE 802.3at (2007),- PoE ++ standard IEEE 802.3bt (2018).

For PoE++, the choice of connectors is fundamentalbecause the powers in play begin to be considerable. Thewiring standards must be respected because, when a liveRJ 45 connector is disconnected, an electrical arc can becreated, which damages the connector’s contacts.All the LCS3 connectors are certified PoE + and guaranteedfor PoE++.

High Density (HD)The main advantage of HD optical fiber solutions (panels,racks, optical fiber drawers, cassettes, etc.) is a largenumber of physical connections in a minimum amount ofspace.Another advantage is that they can be used for a scalable40 or 100 Gigabit installation.

NEW CAT. 8 CONNECTORThe new toolless connector in Cat. 8 STP,with transmission speed (BIT rate) from25 Gb/s to 40 Gb/s, is at the heart of the per-formance of the new LCS³ system.Tested up to 2500 connection/disconnectioncycles and in accordance with ISO/IEC 11801standard - third edition, this new connectorensures a perfect connection in just a fewseconds, giving a link providing excellentperformance levels!

ACCESSIBILITY TO THE NETWORKNetwork identification systems

In its LCS³ solutions, the Legrand Group stillgives more space than average to the alpha-numeric means of identifying the connectionson copper and optical fiber patch panels, inboth standard and high density solutions.All patch panels can, thus, be equipped withlabels available in numerous colors!As for all 19”uprights used for fixing in wiringracks and server racks, they incorporatemarking of the units that can be read fromthe top or the bottom.It is also important to identify the various flows(copper, optical fiber, technical network, etc.).Legrand therefore offers you solutions withcable trays, cords and connectors available invarious colors for optimum identification!

Marking of the unitson 19’’ uprights

NOTEAs servers consume increas-ing amounts of energy, thermalundersizing must be avoided as itcould lead to faults (due to overheat-ing of the infrastructure) and a breakin continuity of service. A data centertherefore requires solutions that pro-vide continuous cooling of the equip-ment, for a building that provideseven better performance!It is therefore important to chooseproducts that provide high thermaldensity, such as air conditioning units,the cold aisle containment, etc.

This high thermal density ensures:- internal modularity of the fansthat can be hot-swapped for ease ofmaintenance, and an optimum powersupply- absolutely no contact between theconnections of the water inlets (lowerpart of the units) and the electricalinlets (upper part)- simple, effective visual feedback forquick identification of alarms

“HOT PLUG” SYSTEMThis system enables components tobe connected and disconnected in aninstallation while energized, withoutany interruption to the system and withno risk of damaging the rest of theinstallation. Even when high currentsare interrupted, continuity of service isassured.The Hot Plug system can be applied tovarious components in an installation,such as the low voltage electrical panel,energy distribution solutions in thecomputer room, IT equipment, etc.

NOTEThe Hot Plug system is also used for managing maintenance andthe scalability of the installation, enabling the time taken for work tobe reduced considerably and therefore increasing the availability ofdata centers.



Low voltage electrical panelIn the context of the IEC 61439 stan-dards, which govern low voltageelectrical panels, the concepts of con-nection/disconnection associated withrequirements for upgrading the panelare essential. To meet these require-ments, the Legrand Group uses twoindexes which provide information onthe level of continuity of service of anelectrical panel, which are assigned tothe panel according to its character-istics and its components: the ServiceIndex and the Mobility Index.

SERVICE INDEX (IS)French reference index, its aim is todefine the service level provided byany type of low voltage distributionpanel when undergoing all types ofwork, during the three phases of its life(operation, maintenance, upgrading). Ittakes the form of a 3-number code.The IS, through the choice it offers,helps to augment the continuity ofservice and the safety and security ofthe installation.Although this index is not mentioned inthe IEC 61439 series of standards, thereis certainly some correlation, in particularwith regard to the.”Mobility index”.

MOBILITY INDEXInternational reference index deter-mining the design of the functionalunits in the panel, it takes the form of a3 letter code (see page 38).

STANDARDSThe main preliminary step for sizingthe energy source(s) is to carry outa “power analysis”, to ensure thereis an optimum power supply for allthe consuming receivers in the datacenter: lighting, heating, air condi-tioning and utilities… and of coursethe racks and IT systems. This poweranalysis must take the conditions ofuse, possible degraded modes (nopower) and even electromagneticinterference (harmonics) into accountin the dual interests of continuity ofservice and energy saving. The qualityof the energy (standard EN 50160) andthe distribution conditions (supplier,operators, proportion from renew-able sources, etc.) are parameterswhich must also be managed in thisoperation.Standard EN 50600-1 gives gen-eral design recommendationsfor data center installations andinfrastructures.Standards EIA/TIA 942-A (US version)and EN 50600-2-2 (EU version) giverecommendations on energy distri-bution, in particular for the Serviceindex/Mobility index.The Green Grid, an international ref-erence system, also provides adviceon configuring energy distributionsystems.In addition to specific standards, it isalso essential to comply with safetystandards for electrical installa-tions (IEC 60364-X set of standards)regarding equipment choice andimplementation, protection of people,and installation safety. Similarly, allactive products (servers, switches,etc.) integrated in racks must complywith the IEC 60950 standard regardinginformation technology equipmentsafety, to which they must refer.For further information,see p. 60 to 65 (Safety and Security)

It consists of converting the current supplied via the raw mainssupply twice before supplying the installation: once to DC via therectifier, and once to AC via the inverter. This provides increasedprotection against power cuts and micro-cuts, interference,frequency variations, voltage dips, overvoltages, lightning, etc.

Energy efficiencyAll Legrand UPS are optimized so that they provide maximumenergy efficiency between 45 and 80% load, which ensuresoptimum efficiency in the various types of architecture (n+1 or 2n).

16% CAGR expected betweennow and 2026 regardingenterprise cloud spending

REQUIRED FLEXIBILITYOF THE SERVER ROOMThe temporary physical reduction in thesize of server rooms will lead to increasedenergy density due to the use of servers withmedium and high density power requirements. Due to the changing needs in termsof numbers of racks and power and thefluctuations that this involves in regard tocooling, it is essential for the design of serverrooms to be flexible and scalable.

A MODULAR APPROACHIt must therefore be possible for the capacityof a modern server room to be increased ordecreased quickly and easily. It is thereforeclear: the building of server rooms requiresa modular approach in order to provide anoptimum response to current and futureneeds and to changes in the market.A modular approach to building a serverroom involves a great deal more than simplymaking it easy to add or remove racks:modularity also applies to the energy distribution, the backup power supply, the cooling,the network, etc. This enables the need toconstantly adapt the consumption of theserver room to the needs of the computerinstallation.

In the era of virtualization and cloud computing, enterprise cloud spending is expectedto grow at a 16% compound annual growthrate (CAGR) between now and 2026 (source:Wikibon). This rapid growth will have a majorimpact on how we design our server rooms,with scalability becoming vital. In fact it willbe essential for a server room to adapt toconstantly changing requirements dictatedby the growth in volumes of data.Conversely, virtualization and cloud computing will have less and less impact on thephysical sizing of server rooms. But thistemporary phenomenon will be followed by asignificant increase which will then necessitate the physical expansion of server rooms.The massive growth in data volumes forecastover the coming years will contribute to thisconsiderably.

All Legrand Group’s data centersolutions are designed based on theconcepts of scalability and flexibility.

3 SCALABILITY › LEGRAND GROUP’S RESPONSE

Legrand recommends that you take thescalability of the infrastructures into accountat every stage.

When designing the data centerOur teams are available to support you inconsidering this as a whole!When selecting solutions to beimplementedThis means choosing products that provideaccess to greater performance withminimum dimensions and which enable youto keep some space in reserve, providing anoptimized and scalable area.

DESIGNLegrand can work with you on the entiredesign of your infrastructure: the grouphas a centralised expert department whichcan provide you with expertise in its variouscompetitive areas, working with you to definetechnical solutions by looking at the projectas a whole, over and above single products.Our expertise is your assurance of having adata center with optimum design, guaranteeing you reliable communication between thevarious interfaces.

AnticipateneedsThe infrastructure requirements of all data centers have to change,all the more so with the increasing emergence of cloud computing.Anticipating future needs is therefore essential: adapting the physicalspace in the data center for the envisaged workload and the possiblechanges is therefore a real necessity.

CHOICE OF SOLUTIONSThere are two objectives: to optimize thespace for optimum performance in minimumspace, and to keep some space in reserveso that new devices can be added while theinstallation is energized.

Optimizing the space

COMPACT PRODUCTSThe LCS³ range provides an infrastructurewhich supports today’s most commonly usedprotocols on Ethernet and Fiber Channel. Ithas been designed and produced to optimizespace and make future upgrades easier.It gives you access to higher performancelevels without requiring any additional space:the copper system now comprises HD panelsthat house 48 ports (4 blocks of 12 connectors) in the same amount of space as the24port panels, and the HD/UHD optical fibersystem offers innovative panels that canhouse up to 144 connections in 1 U!As for Legrand’s smallsized protection solutions, such as the 4module 4pole RCBO,they guarantee space saving with no loss ofefficiency!

MICRO DATA CENTER SOLUTIONSTo make you benefit from an efficient andscalable IT infrastructure in minimum space,Minkels and Legrand have developed microdata center solutions. Our experts havebrought power distribution, cooling, housingand mechanical infrastructure together inan allinone solution. The micro data centersolutions offer you a complete and compactserver room on which specific modifications can be made to meet your exact needs.Numerous options and accessories areavailable to expand the infrastructure as yourneeds evolve!

Micro data centersolution



COOLING SOLUTIONSMinkels’ Free Standing Corridor offers youthe ultimate freedom to add or switch racks,or integrate equipment and racks withabnormal dimensions during the product’slife cycle.The selfcarrying character of the FreeStanding Corridor offers a large number ofadvantages, among which: ultimate modularity: you can install, removeor change the racks quickly and easily, optimal flexibility: you can fit different typesand sizes of racks, for example for storageand network equipment at a later time. optimal system integration from day 1: youcan, for example, fit all integration parts formonitoring, security and the extinguishingsystem before placement, even for the rackswhich have not yet been installed.

Keeping some space in reserve

PHYSICAL SPACEIt is important to keep some space in reserve in the secondary distribution board tomaintain the scalability of the data center. Arack that is large enough to provide sufficientreserve space must therefore be chosenfrom the outset. With preequipped spacein reserve, there is no need to switch off themain supply when making modifications tothe installation: scalability and continuity ofservice are assured.

ENERGY DISTRIBUTIONThe use of modular UPS, with a chassis witha high enough rating for maximum capacityand equipped with modules for the currentrequirements, provides a highperformanceresponse to scalability requirements.The versatility of Legrand’s PDU range,available in both standard and customizedconfigurations, offers greater flexibility andresponsiveness. The modular design ofZEROU and 19’’ 1U customized solutions,with expandable outlet and function modules,allows new specific configurations as yourneeds evolve.

Scalability requirements in regard to capacity,resulting in increasing numbers of servers,concern 3 main areas:

ConnectionVarious systems are necessary, from solutions prefitted with connectors to Hot Plugsolutions for IT equipment, as well as highdensity solutions and flexible electricaldistribution.PowerIncreasing the capacity of a data centerinvolves the installation of powersolutions which combine adaptabilityand high performance both in termsof the architecture and their technicalcharacteristics.CoolingThermal high density solutions providecontinuous cooling of the equipment!

Increasecapacity

Since IT equipment requirements change, the infrastructuresmust adapt to your requirements and allow upgrading withoutdisturbing the operation of the existing installations.Some systems incorporate this concept: using a particular technology (modular UPS system) by design (cold aisle containment, PDU and structured cabling,

electrical distribution in the computer room) by means of standards (eg: IS standard for distribution panels).

CONNECTIONDigital infrastructure

The LCS³ system provides solutions withsmall copper and optical fiber cablesprefitted with connectors.LCS³ solutions can be installed at the topof the rack, by fixing on cable trays, whichincreases the flexibility of the installation andthe server rack capacity.To be noted: LCS³ links, either with barecables or cables prefitted with connectors,can perfectly be added in an installationequipped with the EZPath cable routingsystem. (for further information, see p. 65)

High Density (HD)HD solutions allow upgrading because theyare small. This ensures a high degree ofavailability of spaces for adding equipment inorder to provide higher performance levels.

Electrical distribution for PDUsThis involves choosing the right electricaldistribution mode for the PDUs.For optimized distribution, Legrandrecommends a Legrand BUSBAR solutionMR DC with tapoff boxes, with or withoutmetering. When it includes metering, thissolution is ideal for colocation data centers.The complete unit, which can be connected tothe power and to the metering bus while theinstallation is energized, provides maximumflexibility as its equipment is easy to adaptto the type of power supply required (threephase/single phase, 3263125160 A).For small applications, Legrand offers Plug& Play solutions for cable routing and theIS 223 distribution panel. Offering goodscalability at an optimum cost, this solutionis ideal for enterprise data centers.

NOTEWhen adapting an infrastructure in order to increase adata center’s capacities, it is essential to control capitalexpenditures (CAPEX), which can be substantial.This is possible by resorting to solutions which allow anevolution of capacities at the rate of the data center’s realneeds. Implemented in a modular design, these solutionswill limit the engendered operating expenses (OPEX),all the while controlling scalability and availability.



“Hot plug”This system enables VDI equipment to beconnected/disconnected while is energized,with no damage to the installation and withno break in service. (for further information,see p. 36)

POWERA modular architecture

With the Legrand range of modular Uninterruptible Power Supplies it is possible toadd power and battery modules, and thusto increase the capacity inside the UPSitself. Additional advantage: the connectionsupstream and downstream of the UPS arealready made.The Legrand range of parallelable UPSenables, together with IS optimized distribution solutions (HX3 range), an additional UPSto be added with no break in service, andprovides for the necessary upstream anddownstream connections.With the KEOR HP solution, it is thus possibleto connect up to six UPS in parallel to providevery high power capacities.Note: the physical location of the UPS andsome reserve space (unequipped space)must be provided in the electrical panel!

“Hot swap” systemLegrand UPS incorporate the Hot Swapfunction which enables UPS to be replaced/added while energized, with no damage tothe installation and with no break in service.(for further information, see p. 40)

USB and Ethernet Mix and MatchCascading

Choose the best way to daisy chain up to8 PDUs using one of the two USB ports ofRaritan’s iX7 controller. Or leverage the

Gigabit Ethernet port for cascading and thefree USB ports for other applications.You can mix and match USB and Ethernetconnections, and even include other PX andEMX products as part of the daisy chain.

Physical upgrading of the white roomIncreasing the number of racks requires theaddition of data and electrical connections. Italso implies sufficient air conditioning powerin the room.

COOLINGThermal high density solutions providecontinuous cooling of the equipment: theassurance of a highperformance buildingthat can incorporate upgrades without anydamage! (for further information, see p. 12)

SAFETY AND SECURITY4

As data centers house strategic dataessential to the operation of thecompanies to which that data belongs,it is essential to ensure the data isprotected. For this, two aspects mustbe considered.

EQUIPMENTAs data security is crucial for any datacenter owner (or for the owner’s customers), increased protection of the equipment on which this data is located must beimplemented.

PEOPLESince data centers cannot operate withouthuman intervention, whether this is formaintenance or monitoring purposes, it is vital to ensure optimum safety and security forall workers/visitors who need to be onsite orin the data center.

In 2015, approximately 10% of thebudget for building a data center wasallocated to safety and security of thebuilding, with more than half of thisbeing dedicated to fire detection andsuppression.

EMX EnvironmentalRack Controller



ELECTRICAL PROTECTIONShortcircuits, overloads, voltage peaks, etc.are electrical events against which protection isprovided by circuit breakers. It is important toprovide total discrimination between the various levels of protection and a very high level ofselectivity.Compatible with all Legrand PDUs, a surgeprotection module protects equipment againstovervoltages. As for ZEROU PDUs, a powersupply cord locking system (for C13 and C19outlets) guarantees absolute safety.For further information,see www.datacenter.legrand.com

CABLE ROUTINGThe EZPATH mechanical firestop caulkingsystem provides optimum protection againstfire spreading, whatever the load factor of thecables.Because it enables cables to be added or removedwithout affecting its firestop performance, it isparticularly suitable for infrastructures requiringmodifications to the electric wiring, and ensuresdurable, flexible and sealed cable routing ininstallations.For further information,see www.datacenter.legrand.com

POWERThe power devices are key components in a datacenter, and particular attention must be paid totheir safety and security. It is essential to manage the risks concerning these devices, using:

Optimum manufacturing techniquesThe manufacture of the insulating parts ofLegrand transformers and capacitor banksusing vacuum pressure moulding avoids any riskof fire breaking out, compared with manufacturing technologies using oil for cooling.

Capacitors in compensation systemsThese do not contain oil or gas and have a triplesafety system, comprising fuses and pressuremonitoring devices. The materials used complywith standard UL94V2. This helps to limit therisks of fire as much as possible. The capacitor banks can also optionally be equipped withsmoke detectors.

Optimization of the electricity systemManagement of the harmonics in UPS will, forexample, provide a better quality system, forgreater durability of the electrical infrastructure.

Residual current monitoringBy measuring current flowing in the groundwire, the residual current monitoring option(available on several of Raritan’s intelligent PXPDUs) reduces the risk of electric shock.Residual currents generate a system alert,keeping technicians safe!For further information,see www.datacenter.legrand.com

FIRE SUPPRESSIONIf a water fog or sprinkler fire suppressionsystem is used in the white room in acontainment situation, it is necessary toensure suppression of the fire (in the eventof an alarm) via an opening in the roof.For this purpose, Minkels elaborated twohighly efficient solutions incorporated in thecold aisle containment systems: an opening roof system, either automaticabove 50°C or controlled electronically. Drop Away Panels : they ensure theseamless integration of aisle containmentsolutions with sprinkler or water mistsystems. In the case of a fire in the datacenter, the plastic Drop Away Panelsautomatically soften and fall down so thatthey do not form an obstruction whensprinklers are activated. The system isspecifically designed for use with sprinklerinstallations.For further information,see www.datacenter.legrand.com

LED LIGHTINGMinkels energyefficient LED Tubes deliverimproved visibility in data centers, providinga safer and healthier working environment.Safety certification to the highest level (IEC62471:2006) offers the user a guarantee ofexceptional eye protection.For further information,see www.datacenter.legrand.com
