Executive Summary Virtualizationtechnologies, includinghypervisorsandcontainers,arenowthedefaultmethodusedtodeliver IT infrastructure in both enterprise and private cloud environments. While virtualizationprovides a technical foundation for these environments, it is imperative that the infrastructure alsodeliverstheoperationalbenefitsnecessaryforbusinessestorunsmoothly.Therearemanyaspectstoefficiency,includingperformanceandeconomicmeasures,alongwithoperationalelements.

One challenge has beenmanaging resourceswithin a virtual infrastructure,whilemaintaining insightintotheapplication.Storageinparticularhasbeenanissue,withstorageusinglogicalvolumesthatdonotmap to virtualmachines or their applications. IT administrators need visibility into resources inorder to optimize application performance while minimizing consumption. Without visibility intoutilizationonaVM level, applicationmanagementbreaksdown. This canhave significant impactonapplicationperformanceandefficiency,andtheeconomicsofthedatacenter.

In this paper,we examine the performance and economic benefits of a storage systemdesigned forvirtualserverandcloudenvironments.Traditionalstoragemanagementisfocusedonmanagingstorageresource capacity and allocating those resources to multiple hosts.

Evaluation Overview EvaluatorGrouputilizedtwodifferentvirtualizedapplicationworkloadsused inenterpriseandprivateclouddeployments, virtual desktopVMs (VDI) and virtual application servers. TheseworkloadsweregeneratedutilizingthestandardIOmark-VDIandIOmark-VMbenchmarks.

EvaluatorGroupcomments:Applicationbenchmarkswereusedtoprovidereal-worldperformanceandprice/performanceresults.Unlikeartificialworkloads,thecertifiedIOmarkresultsprovidemeasurableapplicationperformanceandprice/performancedatathatiscriticalforITorganizationschoosingstoragefortheirenvironments.

Storage Considerations in Virtual Environments Virtual workloads place high demands on the storage infrastructure, primarily in terms of theperformance requirements. Additionally, managing applications can be challenging in virtualenvironments, due to the lack of direct visibility into the causes of performance problems. Storagesystems for virtual application environments need to meet the management and performancerequirements:

• Predictablehigh-performance,ideallyusingallflashtoeliminatelatencyspikesofHDDmedia• Capacityefficiencythroughuseofin-linedatareductiontechnologiesincludingthin-provisioning,

datacompressionanddeduplication

• Integration with the hypervisors to facilitate management of the virtual infrastructure by ahypervisoradminorITgeneralist,withoutrequiringdedicatedstorageadmins

• Qualitatively, a low management overhead to minimize the amount of time spent managingstorageratherthanmanagingapplications

Tintri Test Configurations TestingTintriperformanceutilizedstandardbenchmarks,designed tomeasureperformance invirtualenvironments,usingapplication-focusedtesting.

Quantitative Testing

The performance evaluation consisted of running a VDI application workload (IOmark-VDI) andseparately running a virtual server application workload (IOmark-VM). The storage system wasoptimized to establish the maximum level while running a particular workload. The maximumperformanceofaconfigurationwasdeterminedbyaddingmoreworkloadsuntilthestorageresponsetime’s thresholds rose above IOmark’s required maximum values. The details of IOmark-VDI andIOmark-VMaredocumentedinAppendixBalongwithfurtherdetailsintheIOmarkcertifiedtestreportspublishedontheIOmark.orgwebsite.

Qualitative Testing

The experiential testing occurred during configuration, setup and management of the Tintri systemrequired during normal operations, and during configuration of performance and other testing.Qualitative assessments and statements are based upon Evaluator Group’s experience using otherstoragesystemsandourexperienceconfiguringsystemsthathavebeentestedintheEvaluatorGrouplabs.

Tintri Quantitative Test Results It is critical to evaluate a system based upon the applications thatwill be used in production. Eachapplication has its own I/O profile, and performance on one type of application is not indicative ofperformanceofanotherapplication.Inadditiontothedifferencesinworkloads,thecapacityutilizationalongwith the provisioning of storage forworkloads can differ greatly. We evaluated the twomostcommon application types used in virtual environments, virtual desktops (aka. VDI) aswell as virtualserverworkloads.

Tintri Usability Testing Usability Criteria Themany qualitative factors involvedwith using a system are often just as important as the price /performance attributes.

Evaluation Summary Efficiency in virtual application environments requires equipment that provides goodprice/performance and integrates with the infrastructure to increase operational efficiency. Theproven performance of Tintri for both VDI and server VM workloads are validation of the strongeconomicsoftheTintrisystemtested.

Theabilitytoanalyzecapacityandperformanceonaper-virtual-machinebasisprovidesoperationalefficiencies and is a differentiating factor for Tintri. This is due in part to the fact Tintri storagesystemscanprovideresolutiononaper-virtual-objectbasis,ratherthanatavolumeorLUNlevel,asistypicalwithblockstoragesystems.Additionally,Tintriaddstoolsandmonitoringcapabilitiesthatgobeyondthoseofcompetingstoragesystems.

Storage capacity efficiency is another aspect that directly impacts the economics of the overallsolution. All-flash storage systems have become key part of most solutions designed to achievepredictablehigh-performanceacrossmultiplevirtualapplications.However,duetothecostofNANDflash media, it is imperative that the capacity is utilized efficiently, leveraging data reductiontechnologies when possible to decrease the amount of capacity required. For this reason, storagecapacityefficiency,orasystem’sabilitytominimizephysicalcapacityconsumedforagivenamountofdatastored,isanotheraspectthatdirectlyimpactstheeconomicsoftheoverallsolution.

Tintri’sdatareductiontechnologiesprovedtobemoreefficientthananysystemEvaluatorGrouphastested to date. For virtualized server workloads, the data reduction rates achieved by Tintri wereidenticaltothedatareductionpotentialofthedatabeingstored.Usingserverapplicationdatawith2 to 1 compressibility yielded data reduction rates of 2 to 1. For persistent VDI workloads, Tintriachieveddatareductionrates60timesthatofsystemswithoutdatareduction.TheseratesarehigherthanVMwareandCitrixclaimsfortheirlinkedclonesornon-persistentdesktops.Thisisasignificantoutcome, enabling IT administrators to chose the type of VDI deployment based onmanageabilityrather thanconsidering thespaceefficiencyadvantagenon-persistentdesktops typicallyhaveusingotherstoragesystems.

These certifiedbenchmarks reportedbyTintri forbothVDIandVMworkloadsprovideamethodofcomparing Tintri’s price/performance to other systems, using a standard benchmark designed forvirtualdesktopandvirtualserverapplications.

Grouptestinfrastructure.Therewerenoreliabilityorsystemunavailabilityeventsoverthecourseofmultipleweeksoftesting.

Final Observations Performanceisoneimportantconsiderationwhendetermininginfrastructurecomponents.However,the more important factor is a system’s price for a given level of performance, particularly forworkloads that scale out. In today’s highly virtual datacenters, workloads are scaled out acrossmultiplephysicalserversandstoragesystems,withnooneapplicationconsuminganentireserverorstoragesystem. ITarchitectshavefounditfarmoreeconomicaltousethisscale-outmodelforthemajorityofapplications, leavingonlya fewapplicationstorunonphysicalsystems. Withscale-outworkloads,theprice/performanceofasystemismoreimportantthanthetoplineperformance.

Beyond the economics of price/performance, are the storage capacity considerations, along withmanageability. Typically, IT administrators assume that capacity utilization is constant acrossdifferentstoragesystems,withonesystemprovidingnearlythesamelevelsofefficiencyasanother.However, this isnot true,particularly forsomespecialworkloadssuchasVDI thatcanachieveveryhighefficiencieswhendatareductionisappliedataper-virtual-disklevel.

Althoughmanystoragevendorshaveplug-insforhypervisors,thedegreeofintegrationprovidedbyTintri enabled seamless management from either the VMware vCenter console, or Tintri’s webmanagementinterface.Allneededfeatures,includingsnapshotsandcloning,alongwithperformanceand capacity tracking, were available via either interface. Together, these features reduce themanagementoverheadandallowITadministratorstofocusontheVMsandapplicationsratherthantheunderlyingstorageinfrastructure.

Finally, Tintri’s ability to manage objects at a native virtual machine and disk level provide muchbettercapacityoptimizationthanalternativesystems.ThisenablesITarchitectstochoosedeploymentoptionsthatalignbetterwiththeirusersneeds,ratherthanbeingforcedtochooseoptionsbasedonlimitations of their storage infrastructure.
