The South African Department of Trade and Industry (DTI) had already completed a pilot of server virtualization for its disaster recovery and wanted to extend the benefits of server virtualization to its main production site, where it was running out of floor space and power. This is their success story.

South African DTI Cuts Power and Cooling Costs by 75%

  1. 1. S U C C E S S S T O R YThe South African Department of Tradeand Industry Streamlines ServersExecutive SummaryINDUSTRY DESCRIPTIONThe South African Department of Tradeand Industry (DTI) works to ensureeconomic development and employmentthroughout South Africa. The DTI’stasks, such as producing statistics andpromoting inward investment, requiresignificant IT infrastructure.BUSINESS SITUATIONThe department decided to explorevirtualizing its physical servers to reducepower consumption, free data center floorspace and reduce costs.THE NETIQ DIFFERENCEUsing PlateSpin® Recon, the departmentwas able to identify the best candidatesfor virtualization, determine the optimalhardware for the virtualized environmentand estimate the final cost savings.NETIQ PRODUCTS AND SERVICESPlateSpin® ReconThe South African Department ofTrade and Industry (DTI) operates onan annual budget of more than 16billion rand. Over 1,200 employeesproduce statistics on the South Africaneconomy, promote inward investmentand foster employment creation.The ChallengeThe DTI had already completed a pilotof server virtualization for its disasterrecovery. The department wantedto extend the benefits of servervirtualization to its main production site,where it was running out of floor spaceand power.Many servers only average 5 to 10 percentutilization, yet experience peaks andtroughs of use at different times. It canbe a significant challenge to size newphysical host servers correctly for a givenset of virtual machines. The DTI neededa way to determine which productionservers could be virtualized together onthe same hardware, based on expectedperformance and availability demands.The Solution“We needed to determine whichmachines would be the easiest and mosteffective to virtualize—in a nutshell,those with the lowest average utilization,”said Poppy Tshabalala, chief informationofficer at the DTI.“PlateSpin Recon gaveus a detailed view, pinpointing the serversthat would most benefit from beingvirtualized.”Of the 55 servers in the DTI’s primary datacenter, some could not be virtualizedbecause of vendor software licensingconditions, while others running sharedservices for other departments fell outsidethe scope of the project. The DTI askedLSD to monitor 23 servers in total. Thecombined team used PlateSpin Recon tomonitor the DTI servers for just over onemonth, then produced a detailed reportwith recommendations for virtualization.“PlateSpin Recon worked unobtrusivelyin the background, and had no impacton the performance or availability of ourproduction systems,”said Tshabalala.

However, if all 10 of the virtualservers peak at 80 percent utilizationbetween 9:00 a.m. and 11:00 a.m. on aMonday morning, even more powerfulhost hardware could be massivelyunderpowered.PlateSpin Recon gave the DTI theconcrete data it needed to buildits server virtualization strategy byproviding consolidation scenariosshowing how the peaks and troughs ofdifferent combinations of virtual serverswould combine when those workloadsran together.The Department of Tradeand Industry LowersEnergy Use 75 PercentUsing PlateSpin Recon, the DTIgained a clear view of the pattern ofresource use across its infrastructure.PlateSpin Recon identified 11 serversthe department could virtualize andconsolidate onto a single virtual hostserver. The DTI plans to do so on a two-node server cluster for high availability.This change will produce a 75 percentreduction in power and coolinguse, making the department’s mainproduction site much less expensiveand more environmentally friendly. TheDTI will also save significantly in theongoing acquisition of server hardware,and will be able to focus any investmentin server upgrades on just two servers.“Beyond the savings in hardwareand operational costs, moving to avirtualized server environment meansthat we’ll eliminate all of our potentialsingle points of failure,”said Tshabalala.“Currently, a failure of one of the 11servers will completely knock out theservice running on that machine. In thefuture, the loss of individual processorsor even one entire server from thecluster will not cause any downtime.”Learn more today by contactingyour NetIQ partner or a local NetIQsales representative, or by for contactinformation in your area.“PlateSpin Recon gaveus a detailed view,pinpointing the serversthat would most benefitfrom being virtualized.”Poppy Tshabalala,Chief Information Officer,Department of Trade and IndustryNetIQ, the NetIQ logo and PlateSpin are registered trademarks of NetIQ Corporation in the USA.
