电力云资源池存储域的研究与实现 Study and Implement of Storage-Pool in Electric Cloud’s Resource Pool

国家电网公司从2010年开始建设电力云资源池，存储域作为资源池的必须部分，设计和实现存储域是资源池建设重要部分。首先明确存储域中各种主机和业务对存储的需求、存储域的设计目标和设计原则，提出了两级三类的存储域总体架构，并详细阐述了每类每级能满足的存储需求和业务需求，存储域中监控模块和管理模块的结构和功能也作了详尽说明。该存储域的架构设计不仅可以满足电力云资源池的各种存储需求，符合存储域的设计目标和设计原则，还可以给其他企业的存储域设计和实现提供可借鉴的蓝图。 State Grid Corporation of China (SGCC) has been building electric cloud’s resource pool from 2010, and as the necessary part, storage-pool’s design and implement is the key step. In this paper, the storage requirements analysis of all kinds of host computer and business in storage-pool, and the design aim, design fundamentals are all clearly defined. On this basis, this paper proposed two-level and three-type schema of storage-pool. Storage and business requirements satisfied by each level and each type storage-pool are also explained in detail, and the monitoring model and management model in storage-pool are also declared. This schema of storage-pool can satisfy the storage-requirement, the design aim and design fundamentals. It also provides practical experience for other enterprises.
