Isilon数据保护– FlexProtect
FlexProtect在降级状态下检测和维修文件和目录 基于文件级别保护,以确保快速恢复 Inode/ directories/其它元数据的保护在相同或更高保护级别 在集群范围内分布所有数据、元数据和纠错信息 从OneFS 6.0开始典型的保护方式是N+2:1，这意味集群可 从两块磁盘同时故障的情况下恢复或在一个节点故障下，不 会发生任何数据丢失

NetApp Cluster-Mode的技术优势
业界第一套真正意义上的统一集群存储系统：
多节点集群架构提供超高性能和海量存储 同时支持FCP、FCoE、iSCSI、NFS、CIFS、pNFS主流存储协议 前端主机可以通过任何一个节点来访问数据，实现Global NameSpace 功能 VServer实现逻辑隔离，从而在多租户环境下实现数据访问的安全隔离
实现单一映像管理，利用图形化界面通过任何一个节点就能 对整套集群存储系统进行集中管理和监控，并能通过VServer 实现授权式管理
NetApp Cluster-Mode的技术优势（续）
在线操作能力（NDO）提供数据永久在线能力：
在线卷迁移功能，可以实现
系统的按需扩容 系统的在线负载均衡 数据的层次化存储 系统硬件的在线更换升级 在线逻辑接口（LIF）迁移，可以实现 保证逻辑接口的可用性从而保证数据访问不受物理接口故障的影响 在线调整各节点的负载，避免出现热点节点出现而影响整体性能

具备了4D扩展能力，用户可以Pay On Growth
Scale In：节点本身可以通过增加FlashCache、前端通道卡、后端通 道卡来提升其处理性能和通道带宽 Scale Up：节点可以在线的升级到更高端的型号 Scale Out：可以在线增加节点（最大支持24个节点），随着节点增加 整套集群存储系统的处理能力和最大能支持的存储容量也呈线性增加 Scale Deep：可以连接外部第三方存储实现存储虚拟化
