* FlexVol M is scaled to enhance read performance via a load-balancing, asynchronous mirroring capability. Some applications often require scaling read throughput well beyond write throughput and this scaling option is an effective choice in these cases. Best practice: create a mirror on each node, including the node hosting the source volume so that access is always local Typical use cases: reference data, shared libraries or binaries netboot images * * * * HA HA 重复数据删除 数据压缩 基于指针的克隆 存储空间动态精简分配 B A1 A2 B1 B2 C1 A C R D D ‘ A C B2 Before After Before After Used Free All Protocols NetApp Confidential – Limited Use NetApp DataOntap 8.1 Cluster Mode——提升存储效率的技术 NetApp DataOntap 8.1 Cluster Mode系统管理和监控介绍 NetApp Confidential – Limited Use 可以从集群的任何一个节点来管理整个集群的所有节点 对所有的节点进行全局化管理 compared to NetApp Confidential – Limited Use NetApp DataOntap 8.1 Cluster Mode——单系统映像管理 Command line interface (CLI) System Manager 2.0 基于图形化界面的管理平台 对于大部分的日常管理任务提供智能化向导工具，大大简化了日常管理 OnCommand 5.0 基于图形化界面的管理平台 以资源管理为导向 Cluster View 通过图形化视图监控整个集群存储系统的实时状态 NetApp Confidential – Limited Use NetApp DataOntap 8.1 Cluster Mode——管理工具 * Q/A? * ? 2008 NetApp. All rights reserved. * * * * * * * So far, we’ve only shown one Vserver Vservers are the basis for multi-tenancy operations This shows a second Vserver VS2 – and associated volumes/LUNs and logical interfaces. Notice one node is hosting volumes from both Vservers, VS1 and VS2. This is fine and expected – but the logical separation is maintained. The new Vserver presents another namespace and set of LUNs, that is, another potential CIFS share or NFS mount for the same or different clients – with secure administration and delegated administration. The same or different clients/hosts – can mount it using a logical interface from the new Vserver. Again, each Vserver exists with volumes/LUNs on one/some/all of the aggregates and nodes. You can define 100’s of Vservers in a single cluster. Vservers can use any combination of NAS and/or SAN
