Product Portfolio Introduction Tiered Storage Maturity Model 虚拟存储的三种实现方式 寻找可控制的、可行的虚拟化存储技术 Gartner Hype Cycle Hitachi Universal Storage Platform VM- Externally Attached Storage Architecture 不同的应用特性和数字资产需要匹配不同的存储平台 不同的应用需求： I/O 特性 性能 可用性 数据保存策略 数据保护 数据恢复 虚拟专用存储分区基本概念 Cache Logical Partition (CLPR) 指配一定的缓存 指定一个或多个Raid Group使用这些缓存 Storage Logical Partition (SLPR) 指配一个或多个 CLPRs 制定一个或多个目标端口使用这些 CLPRs Storage Navigator maintains user access control 管理员或用户的管理权限控制 访问控制目录跟踪和控制所有的操作 动态调整虚拟存储系统满足变化的业务要求 * * Storage tiers can be designed around many characteristics including availability, performance, costs, protection. Tiering around: Availability: Raid types, controller architecture etc.. Performance: 15k fast storage (internal) that is typically assigned to the most demanding and important transactional applications. Probably only one RAID type used here. Also probably remote replication used. 10k 300GB internal for daily business/Web applications. Possibly multiple RAID types deployed (could be considered ‘sub-tiers’). Depending on critic business nature remote replication and/or ShadowImage software. 10k FC external storage for daily or less than 24hr/day applications that are not as demanding. Slower external storage (as low as SATA caliber) for saved snapshots, read-only historical data, data warehousing, etc ?? Cost: Use of SATA Protection: Tiering around protection to include VTL and Active Archive Solutions. Data Mobility * * * We need to go back to the original definition of Storage virtualization that visionaries like Vincent Franceschini, the current chair of SNIA helped to develop. This definition comes in two parts: The first talks about independent or common management of heterogeneous storage. All virtualization solutions do this to some degree of success. The second talks about aggregating storage services, and adding new capabilities to lower level storage services. That is close to our definition of services oriented storage! We are the
