Network storage provides high scalability,availability and flexibility for storage systems,and is widely applied to many fields.Particularly,I/O performance is of great significance.Its application is wide and expanding rapidly.I/O performance has already become the bottleneck of the whole performance of computer systems for a long time,and under the condition of the present computer technology,I/O performance optimization method looks especially important.In the paper,I/O performance model was analyzed based on the combination of quasi birth,death process and queuing model,and then solved the model.A number of important related performance indicators and the relationship between them were given.By the way of example,this method can show the I/O performance more accurately.Finally,we got some useful conclusions,which may be used to evaluate network storage performance,and are the basis of confirming I/O scheduling strategy.
