Is your data center infrastructure ready to meet theincreas ed demands of virtualization? Here are some

warning signals that your infrastructure may not yet meetthe increased power and cooling requirements:

Processes for moves, adds and changes are notstandardized and may be manual.

Power and cooling demands have not beencalculated for the consolidated environment.

Your critical power system consists of multiple smallUPS units rather than a centralized UPS system.

You have difculty keeping temperatures in theroom below 80 degrees F before new equipment isinstalled.

You have no way to target additional cooling to rackswith densities above 5kW.

You have not updated your vendor service levelagreements.

The Right StrategyServer virtualization creates a higher performing data center and lays the framework forcloud computing and enhanced disaster recovery. It also introduces power and coolingchallenges that, unless addressed, will limit your ability to realize its potential.

The ChallengesConsolidation and virtualization change the power and cooling prole of the data center. Thebenets of consolidation and virtualization may not be realized if power and cooling strategiesare not evaluated and modied.

phyc scyIT equipment is vulnerable to failures caused by unauthorized access, adds and changes. Server

consolidation concentrates applications on fewer servers, which then need to be protectedby lockable enclosures and software, giving you the ability to monitor and control access andequipment changes.

pw MgmServer consolidation will likely increase the power draw within the rack and may increase rackcriticality. UPS systems must be sized and congured for increased capacity, reliability andredundancy.

HDenser, more powerful servers generate more heat than the systems they are replacing. Bladeservers in particular concentrate heat within a small space. Building air conditioning is unlikely

to be sufcient for cooling consolidated environments and therefore precision cooling needs tobe added. Hot spots that arise from higher density servers may need row-based or specializedhigh-density cooling.

Vby CEnhanced monitoring and data center infrastructure management is critical in a virtualizedenvironment. Data centers need to bridge the physical layer of the infrastructure power,cooling and facilities resources and the IT infrastructure the actual computing, storage andnetwork activity.

Intelligent capacity planning enables enterprises to aggregate and correlate real-time data

across the data center and automate IT applications based on real-time server usage.

Proactive changes to critical systems can be automated more effectively, including asset andcapacity optimization, predictive analysis for energy forecasting and preventive maintenancescheduling.

Mc svcLack of scheduled maintenance and service can cause unplanned downtime in the increasinglycritical environment created by consolidation and virtualization. Extending the useful service lifeof the power and cooling equipment through proper maintenance, predictive monitoring, andkeeping systems up-to-date reduces the likelihood of downtime.

How to Ensure Your Infrastructure Is Virtualization Ready

Here are measures you can take to ensure your infrastructure is ready to adapt to

the changes brought on by a virtualized environment.

1. pfm w cg Your data center power and cooling prole will change with consolidation and virtualization.

You will need to determine power and cooling availability, capacity and redundancy needs for

the data center to identify risks and vulnerabilities that could adversely affect operations.Calculate the power required by your data center and within each individual rack to ensureyou have adequate UPS capacity where you need it throughout the virtualized environment.Look for potential points of failure, where the loss of one power component can threaten the

larger system. Data center infrastructure management technologies can provide insights intocapacity needs. Keeping power line drawings for the room up-to-date can allow you to identifywhere to employ redundancy.

Various cooling analyses can reveal potential risks to your IT environment. A ComputationalFluid Dynamics (CFD) assessment can show you exactly how airow will occur in yourconsolidated environment and where hot spots and other cooling challenges will exist. Your

room and rack power loads can help you determine where additional cooling might be needed

for hot spots. Redundancy can be built into the cooling system to eliminate potential points offailure.

2. pv hyc cyIn the more critical consolidated environment, equipment needs to be protected fromunauthorized access whether your data center is a single rack or multiple racks.

Utilize racks, such as Knurr racks and cabinets, which have key or card swipe locks ormonitored contact closures, so you can track and authorize access only by qualiedindividuals. Within your racks, utilize smart PDUs, such as the Liebert MPX, which let youmonitor power at the receptacle level and enable receptacles to be activated or turned off.This will help you prevent unauthorized equipment adds and changes that can lead to circuitoverloads, as well as simplifying in-rack power distribution and reducing cabling. Data center

infrastructure management software can also help you standardize and enforce processes forequipment adds and changes.

3. d gh f w ccy vbyIndustry analyst and author Barb Goldworm summed up the reality that should shape yourcritical power strategy: With virtualization, since each server runs multiple virtual serverworkloads, the server becomes a single point of failure. This escalates the issue of availabilityfor that physical server. If you put all your virtual eggs in one basket, then you need to takevery good care of that basket.

UPSs installed years ago may not have the capacity or reliability required for upgraded servers

or blade servers common to consolidation / virtualization projects. Ensure that UPS sizing and

backup are adequate for todays needs and future growth. Make sure you calculate your UPSsize based on the full load of protected equipment not nominal loads, which are estimatesof average loads and could result in undersizing your UPS capacity.

Implementing a high-density system conguration to increase efciency and performance isimportant, but it is also important to ensure those improvements do not come at the cost of

reduced availability.

To achieve the highest levels of availability, data center managers should examine theirexisting power infrastructures closely to identify and eliminate single points of failure.

Power protection, like computing, can benet from consolidation of multiple smaller systemsinto fewer, more powerful systems. When total room load exceeds 40kW, consider replacing


6/126

rack-based UPS systems with larger modular systems, such as the Liebert APM UPS, or withroom level systems, such as the Liebert NX with Softscale technology. The Liebert APM ts

in the rack row and offers the highest reported UPS efciency. It is scalable in 15kW modules forboth capacity and redundancy.

The Liebert NX provides higher capacity, reliability and redundancy than rack systems. TheLiebert NX with Softscale technology lets you increase capacity via a software key, withoutadding hardware.

4. ic h by f y upsYou may be using the same line-interactive UPS systems in your racks. However, theconsolidated environment increases criticality, and you may be better served by online UPSswith fault-tolerant design. The online Liebert GXT3 rack UPS is twice as reliable as morecommonly used line-interactive UPSs, as measured in MeanTime Between Failure (MTBF).Thats because it has an internal bypass that allows power to continue to protected equipmentin the event of a UPS component failure. Room-level UPS systems, such as the online LiebertNX, have even higher reliability due to their bypass technology and longer lasting batteries.

5. p f w cyThe critical environment of consolidation and virtualization will likely mean you want to addredundancy to your power system. The servers you use will likely be dual corded, which means

they are designed for power redundancy. The highest level of redundancy is providing aseparate UPS, PDU and circuit for each cord. Exactly how much power capacity and redundancyyou need depends on your organizations sensitivity to downtime and your budget.

For enterprises seeking to achieve scalability without adversely impacting availability, N+1

redundancy remains the most cost-effective option. In an N+1 system, multiple UPS modulesare sized so that there are enough to power connected equipment (N), plus one module for

redundancy (+1).

6. ic h ccy f y cg ymHigh-density rack congurations have become a best practice for virtualized data centersseeking the highest levels of capacity and efciency. If the heat from a rack is not effectivelyremoved, the performance, availability and lifespan of the virtualized servers can be reducedsignicantly. As you adopt the latest server technologies in your data center, you may beexposed to higher failure rates, especially in the top third of the racks where heat builds up.

The right cooling systems can eliminate the constraints to server deployment caused by highertemperatures, allowing you to fully populate your racks.

If you are using building air conditioning for your IT spaces, consolidation will likely createa need for dedicated perimeter cooling, row-based cooling or high-density supplementalcooling. Compared to comfort cooling, dedicated systems provide year round cooling, movemore air, eliminate large swings in temperature and humidity, and provide higher levels of air

ltration.

Perimeter precision cooling is available in many congurations in form factors and heat

rejection methods. Systems from Emerson Network Power include the ceiling-mounted LiebertMiniMate2, oor mounted Liebert DS and Liebert Challenger 3000, or the wall-mountedLiebert DataMate.

Row-based cooling systems include the Liebert CRV. Each unit provides up to 35kW of coolingcapacity and uses energy-saving compressor and fan technologies that continuously matchcooling to the load. It also uses unique Liebert iCOM controls which allow the teaming ofmultiple cooling systems. And it can be serviced right in the rack row.

For high-density situations where supplemental high-density cooling is needed, the LiebertXD family of products can be ideal. These systems bring cooling closer to the rack andtherefore provide an effective and efcient solution for high-density issues.

More efcient precision cooling technologies in virtualized environments reduce total cost ofownership (TCO). Using EC Plug Fans and digital scroll compressors, these systems can leadto energy savings of 65% compared to conventional components, and also reduce wear andtear on equipment. Aisle containment systems can also increase cooling capacity by returninghigher temperature air to the cooling units, allowing them to run more efciently.

Turn to your local Emerson Network Power data center design expert to evaluate your cooling

needs and recommend just the right solutions.

7. pg, mg c hgh fcmgmWith server consolidation and virtualization, the need to plan for capacity usage and to know

what is happening within equipment racks at any given time becomes vital.

Data center infrastructure management technologies provide real-time visibility into criticalsystems, as well as automated management capabilities. Capacity and space-planningtechnologies, such as Avocent Data Center Planner, enable managers to aggregate andcorrelate real-time data from IT and infrastructure technologies, so they can get the highestefciency and performance from equipment adds, moves and changes.

Ensure Liebert UPS systems are network-enabled, using technology such as the LiebertIntellislot Web Card. Software such as Liebert Nform will provide alerts for adverse system

or environmental conditions, and allow you to conduct graceful shutdowns of IT equipment inthe event of extended power outages.

Various rack-mount hardware devices and software technologies are available for monitoringof temperature, humidity, water leakage and contact closures.

Remote monitoring of power and cooling systems from Emerson Network Power is available if

you do not have the internal personnel to perform these important tasks.

8. ug vc mcThe addition of higher-criticality IT equipment is an ideal time to revisit your service and

maintenance processes and contracts.

Extending the useful service life of the power and cooling equipment through propermaintenance, predictive monitoring, and keeping the equipment up-to-date increasesequipment life spans and maximizes performance.

Service level agreements should be reviewed at this time and modied with higher criticalityin mind.

Emerson Network Power service providers are factory certied and are part of a continuoustraining program. When disaster hits, Liebert service contracts guarantee a four-hourresponse time.

Even smaller rack-mount UPS systems can be covered by maintenance and service contracts.

The Liebert Power Assurance Package provides on-site service and battery replacement

programs for the rack mount Liebert GXT3 UPS, from 1000VA and up.
