內容安排NAS、iSCSI、SAN技術簡介IBMNAS存儲產品整體介紹傳統NAS——NSeriesScaleOutNAS——SONASNAS、iSCSI、SAN技術特點及使用簡介數據結構應用系統操作系統文件管理系統RAID控制磁盤讀寫I/O調用模式數據結構結構化數據半結構化數據非結構化數據NAS為解決數據共享問題和優化文件（File）存儲而產生的存儲技術文件管理系統在存儲設備端，是文件服務+IP的一種技術多應用于非結構化數據（文件）、OLAP、數據共享SAN為解決DAS的問題而產生的存儲技術是DAS+網絡的一種技術多應用于OLTP聯機交易系統iSCSI為解決SAN的成本、兼容性、不易部署和管理等問題而產生的技術是SAN+IP的一種技術，所以iSCSI也叫IPSAN多應用于PC服務器平臺NAS、iSCSI、SAN技術特點NAS、SAN、iSCSI

技術優勢一覽表NASSANiSCSI結構化數據

（數據庫）√非結構化數據

（文件）√共享√中小型數據庫√優勢1.優化文件系統，文件存儲性能好2.天然共享架構和安全保障，滿足共享需求

3.易管理、低成本

4.開放、兼容性好1.結構化數據情況下性能好1.易管理、低成本2.開放、兼容性好IBM存儲產品整體介紹IBM存儲產品整體介紹Distributed,OpenSystemsHetero-geneousMainframe,SystemiEnterpriseClassMidrangeDS8000Solutionformainframe,I,&opensystemsplatformsDisasterRecoveryacross2&3sitesSecureencryptionContinuousavailability,nodowntimeforupgradesExtremelyfastresponsetimesSVCBlocklevelvirtualizationofmultiplevendorenvironments,includingIBM,EMC,Hitachi,Sun,NetApp,HPandothersDS5000Opensystemsenvironmentsupport,includingIBMisupportCostefficientstorageforcapacitiesupto448TBsModularstorageXIVOpensystemssupportEaseofManagementFuture-proofcapacityexpansionandmanagementWeb2.0workloads2sitereplicationAllinclusivesoftwareNASNseriesCombinedNAS(file)andSANrequirementsSimpletwo-sitehighavailabilityApplicationaffinity(SnapManager)ReplicationHeterogeneousgatewaySONASVerylargeperformanceandTBdemandsIntegratedILMAllinclusivesoftwareEntryDS3000Forveryprice-sensitivecustomersFlexibleinterfacechoicesModularstorageNAS分類ScaleOutNAS傳統NASSingleNamespace.Abilitytoscalelargenumbersofclusters.Aggregationofstorageforhighutilization.IndependentscaleofGBs/secofperformancevs.PB’sofcapacity.N+1AvailabilityGeneralpurposefilestorage.Oneortwonodeclusters.Usuallyallowcapacityexpansiononlybehindtheclusters.Costeffective,lowerpricepointseffectivelyaddressingthesmalltomidrangeNASmarketspaceScaleOutNASparallelfilesystemclusteredNASservicesCIFSNFSHTTPSFTPIPLayer傳統NASNAS架構sharedintegrateddiskstoragepoolslocalfilesystemNASservicesCIFSNFSlocaldisklocalfilesystemNASservicesCIFSNFSlocaldisklocalfilesystemNASservicesCIFSNFSlocaldisk傳統NAS——NSeriesIBMNSeries硬件產品簡介N6070N7700N7900N6060N6040N6040
