基于插件模式的私有云存储系统的存储池设计

A Plugin Model Based Storage Pool Design for Private Cloud Storage System

为满足私有云存储系统中采用不同底层存储介质的需求,提出了一种基于插件模式的私有云存储系统的存储池设计.在数据存储层与数据管理层之间建立统一存储层,包含各类插件并基于适配插件提供的动态性能参数,由统一存储层管理器制定存储策略和IO策略,以平衡存储节点流量,提高存储池的整体性能.实验结果表明,该设计可以提高企业存储资源利用率,提升异构存储横向扩展能力,有效降低私有云存储服务的整体运营成本.

In order to satisfy private cloud storage system using different underlying storages, a new plug-in model based storage pool design model for private cloud storage is proposed. A unified storage layer between data storage and data management is established, which contains various plu-gins and provides dynamic performance parameters based on the adapter plug-in, for managing storage strategy and IO policy, balancing dataflow of storage nodes, and improving the overall per- formance of the storage pool. Practice shows that it can improve utilization of storage resources and improve horizontal scalability for heterogeneous storage, effectively reducing the overall operating costs of private cloud storage service.
