摘　　要：为解决数据中心统一存储环境的架构设计和设备选型困难的问题,提出了存储系统的关键指标集。通过分析清华大学数据中心当前统一存储环境中存在的问题,力图从高可用、高伸缩和自动分级存储等方面建立统一存储环境所需的关键指标,并基于SPC和SPEC的性能评测方法提出了改进的指标。该指标集为清华大学建设绿色节能、高可用、高伸缩性的数据中心统一存储环境提供了重要指导,并促进了数据中心评估指标体系的研究。To solve the problem of architectttre designing and equipment selection in data center＇ s unified storage environment, a set of key specifications of storage systems is presented. By analyzing the current problems met in data center＇ s unified storage environment of Tsinghua University, this paper aimed at forming key specifications necessary for unified storage environment such as high availability, scalability, automated tiered storage and so on. Meanwhile, a improved specification on storage performance is presented based on be- nchmark of SPC and SPEC. The set of key specifications provided important guidance for building green, high available, scalable data center＇ s unified storage environment for Tsinghua University, and promoted the research of data center＇ s evaluation specifications.
