4Introduction
Data center design is changing. Designers are eager to reduce capital expenditures (CAPEX), operating expenses, and the time spent in planning and construction. Yet they also want to retain flexibility for expansion.
For reasons like these, innovative designers are focusing on a modular approach for data center facilities. The advantages of using standardized designs and techniques, industrialized precast assemblies for construction, and prefabricated power and cooling components are becoming clear. Besides the benefits of lower expenses and reduced time to commissioning, modular design makes it easier to offer mixed levels of capacity within the same facility, and allows expansion in phases as requirements change over time. Modular design is also a perfect complement to the modern trend toward infrastructure convergence and cloud computing.
This white paper explores data center modularity as demonstrated in HP Flexible Data Center (also known as Flexible DC or FDC). Youll learn in detail about how HP Flexible DC challenges conventional thinking about data center design. And youll come to understand how FDC delivers on the promise of flexibility, and provides faster, less costly construction, lower capital expenditures, and improved operating expenses.
Levels of modularityFigure 1 shows the basic levels of data center modularity. At one extremeyoullfindthetypicalmonolithicbrick-and-mortar data center. This type of data center is usually custom-built onsite. It can be costly and not very scalable. It often requires a long deployment time. Its design has one goal in mind: build it now for all future eventualities.
Even though its possible to construct such a center using a phased approachthatallowsforsomeexpansion,youstillneedtoplanseveralyearsinadvance.Atthesametime,thecustom-designeddatacenteroffersmanyadvantages,includingaverytraditionalenvironment.Itsspecificallytailoredtoyourneedsandevenoffersa good measure of creature comforts for operators.

This solution takesaminimalistapproach,withracksofserverspreinstalled in an industrial-type container.

The container solution enables very rapid deployment of IT assets when the capabilities of a more permanent facility arent required.

6The core-and-quadrant buildingBasicHPFlexibleDCarchitectureisshowninfigure2.Thedatacenter consists of a central core administrative area surrounded byquadrants,orquads,thatarethedatahallsforhousingITequipment.Thismodularstructureallowsone,two,three,orasmany as four quads around the core. You can construct all quads atonce,oraddtheminphasesasneeded.Soyouhaveanavenue to deal with unpredictable changes in technology today while deferring remaining data center build-out until the appropriate time in the future.
The quadrantsFigure 3 shows details of one quadrant. Each quad contains a datahalltohouseracksofITequipment,andincludesexternalassembliesforpowerandcooling.Aquadrantcanbeconfiguredforacriticalloadcapacityof500,750,900or1,500kW.Thesmallestminimumconfigurationforadatacenterdeploymentisone500kWquadrant;however,withallfourquadsconstructedandfittedout,thefacilitycandeliveranywherefrom2to6MWofcriticalITpower.

71 The only requirement is to specify the maximum capacity (for example, a maximum of 750 kW or 1,500 kW) before construction. This will allow future expansion to that capacity.
Mechanical and electrical components are mounted in external containers that allow easy access for maintenance. Outdoor mounting preserves indoor space for IT equipment and allows forquickandeasydeploymentoffutureelectricalandmechanicalcontainerized infrastructure. External mounting also removes potentialsourcesofequipmentfailure(suchassmoke)fromshutting down a quadrant. Containers have plenty of space for testingandequipment,too.

Youcanevendeployastandalonequadwithoutacore,ifnecessary.This option is ideal if core functions are already part of an existing data center and you need just one quad for expansion.
Mixing capacity in the data center
Ifdesired,youcanconfigureeachquadranttoadifferentlevelof power density and redundancy. One of the best features of thishighlyflexiblesolutionistheabilitytosupportdatacenterconsolidation by arranging IT assets logically. You might want toseparateassetsaccordingtogroup,securitylevel,orevenfunctiontypeforexample,softwaredevelopment,production, or disaster recovery.
Implementing mixed levels of capacity within the data center is comparativelyeasyandstraightforward,simplybyconfiguringeachquaddifferently.Thisapproachcanreducecostsviastrategicalignment of infrastructure and capacity requirements.

8Energy-saving cooling designWedesignedHPFlexibleDCwithenergyefficiencyinmind.Powerand cooling equipment have been selected for the minimum possible energyconsumption,withamajorfocusonpart-loadoperatingconditions.Figure6showsthemechanicalandelectricalsystems.
Mechanical cooling components include prefabricated self-contained air handlers with air-to-air heat exchangers. Overhead convection cooling,usingafloodedcoldroomandhotaisles,reducespowerandwater consumption. Options include DX refrigerant cooling to assist during periods of the year that the local environment cant provide all necessary cooling for the data center IT space.
Maximum use of external cooling
Thissolutiontakesadvantageoftheexpandeddatacenterenvironmental standards published by the American Society of Heating,RefrigeratingandAir-conditioningEngineers(ASHRAE)2. Itusesthetypesofcoolingtypicallyseeninindustrialenvironments,adapting them to the data center.
Thedatacenterisdesignedtoworkwiththeexternalenvironment,usinganaireconomizerastheprimarycoolingsource.Thatis,thebuilding obtains the majority of its cooling by relying on the local climate to absorb and dissipate the heat it generates. This cooling isespeciallyeffectiveinlocationsthathavelargedifferencesinthedry-bulbandthewet-bulbtemperatures(e.g.,largewet-bulbdepression),aconditionnormallyfoundinaridordryclimates. An HP Flexible DC located in such an environment can operate successfullywithoutusingmuch,ifany,mechanicalrefrigeration,savingnotonlyenergy,butalsowater.(Althoughtheyuseoutside airasmuchaspossible,allHPFlexibleDCcoolingsystemsaredesigned tobeeffectiveandprovidehighefficienciesinallenvironments.)
Choice of cooling technologies
Table 1 shows menu choices for cooling technology. Each of these technologies utilizes the local environment to its maximum potential andprovideshigh-efficiencycooling.Allareabletomaintainthedata centerenvironmentwithinrecommendedlimits.Furthermore,thesetechnologies limit the entry of environmental contaminants into the datacenter,whichcanoccurwithtypicaloutdooraireconomizers.
The DX system can be sized for full or part load depending upon the required system redundancy level. Air handlers are located on the exteriorwallsinprefabricatedweatherproofhousings,providingcost-effectiveandtimelyinstallation.
The cooling capacity of the system decreases as the temperature rises. But due to the sensible heat reduction of the evaporative water,theevaporativecoolingsystemefficiencyincreasesastheexteriortemperatureincreases.Moreover,locationsthatnormallyexperience high humidity can still fully utilize any of these cooling systems;thatsbecauseheatistransferredacrossanair-to-airheatexchanger,whichprovidesisolationbetweenthedatacenterspaceand the local environment.

Saving OPEX during operationEnergy is the major cost component of data center operating expenses. For that reason weve developed a state-of-the-art energy evaluation program to help you plan for and select your data center systems.
Duringtheplanningphase,onceyouvemadeyourpreliminaryselectionsforFlexibleDCcapacity,power,cooling,andothersystems,engineeringprofessionalsfromourCriticalFacilitiesServices arm use the evaluation software to perform a comprehensive review of the energy requirements of your facility. The software provides insight into the potential performance of various data centerchoices.Itallowsrunningextensivewhat-ifscenarios, andisinvaluableinthefinalsystemselectionprocess.
Thissoftwareillustratestheadvantagesinefficiencyofourmodularsolutionoveraconventionaldatacenter.Asanexample,weveused this program to evaluate energy usage for a traditional data center andaFlexibleDClocatedinCharlotte,NorthCarolina.
