虚拟化中存储性能瓶颈研究

Research on Storage Performance Bottleneck in Virtualization

随着信息技术的发展,越来越多的行业都向信息化、智能化发展,随之而来,业务系统也不断增多,那么就需要更多的服务器,更多的存储空间来满足业务系统日益增多的需求,传统的增加物理服务器方式难以满足日益扩增的数据存储需求,数据存储也逐渐由单一的硬盘管理向数据中心发展,虚拟化技术的诞生对IT行业产生了重大的影响,也对存储性能提出了更高的要求,尤其是大量并发用户在同时访问数据中心时,更是要求存储具有较高性能,虚拟环境下面临着各种各样的难题,其中最主要的就是存储性能瓶颈。

With the development of information technology,more and more industries are developing towards information and intelligence.As a result,more servers and storage space are needed to satisfy the requirements of the increasing business systems.However,the traditional way of adding physical servers is difficult to meet the ever-increasing demand for data storage.Data storage has gradually evolved from a single hard disk management to a data center.The birth of virtualization technology has had a major impact on the IT industry,imposing higher requirements for storage performance.Especially,when a large number of concurrent users access the data center at the same time,the storage is required to have higher performance,and the virtual environment is faced with various problems,the most important of which is the storage performance bottleneck.
