RecoverPointprovidesmanyfeaturesandbenefitsthatbuild onpreviousRecoverPointversions.The multiplesitesfeatureallowsyoutokeepuptofourindividuallyjournaled copiesofyourproductiondata,enablinggreaterdataprotection, increasedaccesstodifferentpointintime(PIT)copies,andawiderrangeofDR,testing,andbackuptopologies.AndwithsynchronousreplicationoverIP,oneoftheseremotecopiescanbeasynchronouscopywithouttheneedforremotefibreconnectivity.Theintroduction ofvRPAs relievestheneedforphysicalRPAs.TheintroductionofUnisphereforRecoverPointallowsforconsistentmanagementinterfacesandmethodologiesacrossEMCtechnologies.TheRecoverPointRESTAPIinterfaceenablescustomscriptingandapplicationsviastandardRESTfulprotocols.ImprovedintegrationwithVMwareSiteRecoveryManager(SRM)allowsfortestingandfailovertoanypointintimecopy.IntegrationofRecoverPointlocalreplicationandSRDFallowsforlocaljournalcopiesinconjunctionwithremoteSRDFcopies.Thisenablesaccesstolocalanypointintimecopies,whilestillmaintainingSRDFfunctionality.CompleteFIPS1402complianceensuresthattheRecoverPointenvironmentissecure.Otherperformanceandscalabilityenhancements,suchas400MB/sreplicationforasynchronousdistributedconsistencygroups,enableevenmoreefficiencywiththesamephysicalconfiguration.



RecoverPointgivesyouachoiceofthephysicallocationofthecopiesoftheproductiondata. Localcopiesforoperationalrecoveryorremotefordisasterrecovery.WithRecoverPoint4.0andabove,recoverablecopiescanexistinmultiplephysicallocationssimultaneously.RecoverPointisintegratedwithallofEMCsblockstorage,including VMAX(10K/20K/40K),VPLEX,VNXseriesandtheVblock 300/700.WhenusingtheVPLEXwritesplitter,whichcomesinstalledintheVPLEXGeosynchrony code,RecoverPointsupportsnonEMCstorage.

This modulefocusesonthearchitectureandcomponentsoftheRecoverPointsolution.ThegoalofthismoduleisforyoutounderstandthebasicconceptsthatallowRecoverPointtodowhatitdoes.



ARecoverPointsystemisalloftheRecoverPointcomponentsthatareusedtoreplicateandprotectdata.AsystemcanincludeasingleRecoverPointclusterormanyconnectedtogether.ARecoverPointsystemconsistsof:RecoverPointappliances(physicalorvirtual),RecoverPointClusters,Writesplitters,andRecoverPointvolumes.WithRecoverPoint4.0andlater,aRecoverPointsystemcanreplicatedatatouptofourremotecopies.Shownhereisanexamplewithallfourcopiesinfourdifferentremoteclusters.Eachofthesecopieshasitsownjournalandcanbeindividuallyaccessed.Ifwehadalocalcopy,wecouldhaveuptothreeremotecopies.Havingtworemotecopiesinthesameremoteclusterisalsoasupportedconfiguration.PleasenotethatRecoverPoint/SEsupportsamaximumoftwoclusters.Additionally,RecoverPoint4.0supportssynchronousreplicationtoaremotecopyoverIP.Previously,thiswasonlysupportedwithfibre connectivity.Regardlessofwhetheroverfibre orIP,onlyoneremotecopyperRecoverPointconsistencygroupcanbereplicatedsynchronously.Sincealocalcopycanalsobesynchronous,thismeansthatRecoverPointcanmaintaintwosynchronouscopiesatthesametime.AgeneralguidelineforsynchronousreplicationoverIPisforthelinktohavealatency(roundtrip)lessthan10ms.Multiclusterconfigurationsallowforgreaterprotection,increasedaccesstoPiT copies,andimplementationofawiderangeofdisasterrecovery,testing,andbackuptopologies.ItalsoenablesasinglepointofmanagementandminimizesthenumberofRPAsrequiredcomparedwithprevioussharedsplittersolutions.

TheRecoverPointsupportstheRecoverPointSymmetrix writesplitterontheVMAXfamilyofarrays.VMAXhelpscustomersachieveenterpriseclassreliability,availabilityandserviceability.CustomerswhoneedtoprotecttheirapplicationdatalocallyorremotelycanuseVMAXwithRecoverPoint.Forexistingorprospectivecustomers,theSymmetrix splitterforVMAXoffersanembedded,costeffective,andsimpleRecoverPointsolutionforthosethatusetheVMAXArray.



StartingwithRecoverPoint3.5,theVPLEXwritesplitterprovidesanypointintimebusinesscontinuityrecoverytoprotecttheVPLEXplatformacrossamixtureofEMCandnonEMCarrays.Inaddition,RecoverPointcantestreplicateddataonvirtualvolumeswithoutimpacttoproductionapplications.BeforeRecoverPoint3.5therewerethreetypesofavailablewritesplitters:host,arrayandintelligentfabricsplitters.AVPLEXSplittercontainsawritesplitterthatisbuiltintotheVPLEXengine.ThisisasimplemethodtoimplementaRecoverPointbusinesscontinuitysolutiontoprotectthemobility,availability,andcollaborationofVPLEXAccessAnywhereforbothdataandenterpriseapplicationswithVPLEX.TheVPLEXwritesplittersupportslocalandRemoteReplicationusinganysupportedarraytype.TheRecoverPointVPLEXsplittersupportsvirtualizedenvironmentsandclusteringenvironments.TheseenvironmentsincludeVMwareHA,MicrosoftMSCS/Failoverclustering,OraclestretchedRAC,OracleOVMandAIXstretchedclusters.



TheRecoverPointAppliance(RPA) isthedataprotectioncontrollerforRecoverPoint.RPAnodesutilizeprivateLANandsharedRPAvolumesforcommunicationsusingstandardTCPprotocol.NoFC/IPconvertersareneededtoreplicateacrosstheWAN.ThesetofRPAsateachclusterconstitutesanRPAcluster,whereeachclustercanincludebetweenoneandeightRPAs,assetduringRecoverPointsysteminstallation.Theclustersizemustbethesameatallclustersinaninstallation.Innormaloperation,allRPAsinaclusterareactiveallofthetime.Consequently,ifoneoftheRPAsinaclustergoesdown,theRecoverPointsystemsupportsimmediateswitchoverofthefunctionsofthatboxtoanotherRPAinthecluster.Generation5RPAsperformhardwarestatusnotifications.IfaharddriveorpowersupplyontheRecoverPointappliancefails,ahardwareeventnotificationwillberaisedinthesystemlogs.Ifconfigured,theeventwillalsocreateacallhomeevent,sendingasystemrequesttoEMCCustomerService.

Eachcopyofdatainaconsistencygroupmustcontainoneormorevolumesthatarededicatedtoholdingpointintimehistoryofthedata.Thetypeandamountofinformationcontainedinthejournaldiffersaccordingtothejournaltype.Thereare2typesofjournalvolumes: Copy Journals ProductionJournalsJournalvolumesholdsnapshotsofdatatobereplicated.EachJournalvolumeholdsasmanypointintimeimagesasitscapacityallows,afterwhichtheoldestimageisremovedtomakespaceforthenewest.Journalsconsistof1ormorevolumespresented toalltheRPAsforthecluster.Spacecanbeadded,toallowalongerhistorytobestored,withoutaffectingreplication.ThesizeofaJournalvolumeisbasedseveralfactors: Thechangerateofthedata beingprotected.
