28、MC CX3-20/40,FAS3020C VS EMC CX3-20/40,FAS3020C VS EMC CX3-20/40,NetApp的优势全面提高生产力,简单性NetApp存储设备的简单易用是业界公认的简单的操作系统(Data ONTAP)所有设备使用统一操作系统，了解了一个设备，就可以管理全部设备简单性包括SAN/iSAN,LUN管理,DR的数据复制,归档和备份更高的存储空间利用Flexible Volume技术，使得Volume和LUN的管理，与RAID和磁盘的管理想分离易于使用脚本管理用户可以非常方便的通过rsh,ssh和Manage ONTAP APIs来管理存储设备易于和V
29、Mware的命令行结合，便于用户管理虚机(VM),其它厂商的空间分配方法介绍,RG1,RG2,RG3,RG4,RG5,APP1,磁盘,LUN,APP2,APP3,APP4,APP5,APPn,其他厂商在空间分配方法上的局限性,RG1,RG2,RG3,RG4,RG5,APP1,磁盘,LUN,APP2,APP3,APP4,APP5,APPn,访问热点,FlexVol给性能和管理上带来的变革,磁盘,LUN,更好的实现了磁盘IO的平均分布，提升了整个系统的性能 消除了磁盘访问热点的出现 大大简化了存储空间分配和管理上的复杂度,Volume,NetApp的优势灵活性,存储协议支持支持FCP,iSCSI,
30、NFSVMware ESX 3.0全面支持上面三种协议，同时强调NFS协议对于VMware管理带来的便利性。NetApp是目前业界唯一的在同一存储设备上同时支持这三种协议的存储厂商。在SAN/iSAN只见切换非常简单混合磁盘支持在同一存储设备上同时支持FC和SATA硬盘多种接口支持2g 和 4g FC1g(光纤/铜线)和 10g(光纤)以太网TOE/iSCSI 扩展卡,#3 简单快速的存储管理,不仅是简单的存储和LUN的管理，跟是快速的部署能力不需要BIN文件或者其他的需要厂商支配的管理(从低端到高端）在创建RAID组、Volume和LUN是不需要进行长时间的格式化如果VMware的datas
31、tores需要进行空间的扩展，只需要1到2个命令就可以立即完成扩展空间增加即可完成增加磁盘，磁盘柜以及增加额外的环路，均可即可完成,简单快速管理所带来的好处,EMC,EMC,NetApp:30 seconds,65 min.,Clone LUNS,EMC,85 min.,Extend Size of Oracle DB,70 min.,NetApp:30 seconds,NetApp:35 min.,Create RAIDGroups,Volumes,&LUNs,Elapsed Time:,Source:Veritest,5/05.NetApp FAS3020 vs.EMC CX500,2X
32、Improvement,140X Improvement,130X Improvement,NetApp的优势快速有效的虚机(VMs)克隆,VMware ESX 包含了克隆,但是每一个克隆消耗100%的存储空间需要消耗一定的时间完成克隆(实际是数据拷贝时间)NetApp LUN Clone 和 Volume FlexClone几乎是瞬间完成克隆当克隆创建时不占用额外的空间随着克隆的虚机不断的使用，数据不断变化，克隆的LUN或者使Volume会占用变化的空间，非常明显的是swap的空间占用应用创建一个虚机的模板(并经过sysprep)，然后利用这个模板Clone新的虚机利用克隆创建开发，测试，Q
33、A以及报告等数据对大型数据库进行快速克隆,NetApp的优势Thin Provisioning,VMware ESX 包含部分的thin provisioningVMFS或NFS中的Virtual Disks(VMDKs)但VMFS本身并不具备这个能力NetApp thin provisioning对基于FCP或者iSCSI的VMFS提供thin provisioning功能对RDM提供thin provisioning功能,40,Thin Provisioning,NetApp的优势快速备份,NetApp SnapShots快速的“拷贝”而完全没有拷贝所带来的负面影响（时间和行呢个开销）没有
34、性能的影响（不采用写时拷贝的技术）每个卷最多255个Snapshots通过SnapRestore实现几乎瞬间的恢复在Snapshot基础上实现FlexClone和SnapMirror技术能够与VMware结合实现基于SnapShot的一致性备份,不同的快照实现的性能差别,CX500 performance with their snapshots goes to 40%,VeriTest:Network Appliance FAS3020 and EMC CX500:Comparison of Usability and Performance,2600,2730,2860,2990,3120
35、,3250,3380,3510,Elapsed Time in Seconds,CX500 R&W,FAS3020 R&W,NetApp的优势高可靠性,冗余的双控制器冗余的前后端链路RAID-DPSNIA认可的RAID实现，但是没有RAID6所带来的性能严重的开销允许一个RAID组中的任意两个硬盘出现故障，提供比 RAID 1,10,0+1更高的可靠性，但是不需要100%的磁盘的额外开销VMware整合了多个物理服务器，因此后端存储提供更高的可靠性。VMware建议采用RAID0+1的方式，但是这种方式会带来额外的空间开销（增加了成本）,NetApp的优势冗灾,VMware不提供数据的远程复制功能建议采用基于存储的数据复制功能NetApp SnapMirror在level 0的基准复制后，以后的复制支持传输变化的数据块（而不是变化的文件）提供多种复制方式（双向，一对多，多对一，以及级联方式）同步，半同步和异步传输链路可以是IP或者，不需要额外的硬件设备非常简单地打破镜像，resync和翻转同步VMWorld 06所建议的功能,QA,
