Fewer cablesand reduced powerconsumption, thereby loweringoperational costs.Higher throughput andincreased security as trafficleaving the rack is minimised.Flatter network for moreflexible and efficientvirtualisation.Easier design for scale-out(adding racks) – simply add2 power cables and 2 networkuplinks.Simplified cabling and reducedpower consumption, therebylowering operational cost.Provides the ability toreduce operating costs bylowering the baseline powerconsumption.May not generate sufficientsavings to justify for smallerdata centres.Server – increasing thedensity and cooling loads mayrequire additional investmentthat counters benefits.Client – not suited toenvironments requiringhigh processing power andbandwidth.Requires high capital costand down time to managethe migration.Additional overheads willbe required to collect keyinformation where it is notreadily available.Requires a blade chassis(e.g., HP BladeSystem orIBM BladeCenter).There are additionalcomponents to manageunless an element manageris used as part of the systemsetup.This is not the only solutionavailable for lowering baselinepower consumption. Furthergains in lowering baselinepower consumption can beachieved by investing in moreefficient computer processinginfrastructures.Page 37
5TakingFurtherAction5.2 Case Study: Corporate Express – DataCentre Optimisation (Technology Innovation)SynopsisCorporate Express, Winner of the 2008 Australian Sustainability Awards, designed and built ahighly efficient, next generation data centre facility that provided minimal footprint and maximumflexibility, whilst aligning the design to company CSR strategies.‘Better than best’ practice Power Usage Effectiveness (PUE) was achieved by leveraging thebenefits of first virtualising the existing infrastructure to minimise the requirements of the new datacentre facility.Initial virtualisation activities achieved include:• A 70-80 percent reduction on data centre space, power, cooling requirements.• The removal of 184 physical servers.• The reduction of Total Cost of Operation (TCO) of servers by 40 percent.The next generation, purpose built data centre achieved:• A PUE of 1.49 – where 67 percent of all energy is consumed for computer processing.• Minimal construction costs – approximately halved the construction costs for a TIA-942 Tier IIIdata centre.• A reduction of $23,000 per year in electricity costs.Though more suited to larger organisations with a large number of servers, the same principlescan be adapted to an organisation of any size in relation to aligning the data centre strategy withcorporate sustainability objectives. The larger the data centre, the larger the potential savings thatcan be achieved.“A key element in optimising the purpose built data centre was to firstly virtualise theenvironment. This allowed the new data centre to be built with a much smaller footprint,providing large savings on construction costs.Though great efficiency gains have been achieved, ongoing monitoring and adjustment is stillrequired to ensure the optimisation of the hot/cold aisle configurations, keeping temperaturedifferences between hot/cold aisles exactly seven degrees Celsius. This can be achievedby using an aneometer to adjust the air velocity at each individual floor tile to preventovercooling and wasted energy”Mark Jones, Technology Infrastructure Manager, Corporate Expresswww.ce.com.auDownload the full version of this case studyPage 38
