一次基于系统性能分析的存储设备升级
A Storage Device Upgrade Based on System Performance Analysis
摘要
Abstract
China integrated meteorological information service system (CIMISS) collects, processes, stores and shares massive meteorological data.With the equipment running for many years, more and more data are accessed, and the system has a bottlenecks in performance.Through the analysis of the system business requirements and IO of storage disk, it is concluded that the run file system has larger IOPS and high data throughput.The ORACLE database and the data file system need large data capacity, and also have high requirements for the random IO.Configuring new storage based on business analysis and cost performance, it uses 2 Active-Active mode controller of32 GB cache, with SSD solid disk and high speed SAS disk for IO performance requirements, and 4 TB SATA disk with capacity requirements, which can be expanded flexibly.In the implementation using FAST VP function to realize hierarchical data management, through a period of steady running, the run file system has the most"hot"data, accounting for 50.63％ and 34.22％ respectively on SSD and SAS.The access rate of most data in ORACLE database and data file system is low, so these"cold data"will automatically be migrated to SATA disk, accounting for 64.7％ and 74.31％ respectively.关键词
