摘要: 为研究影响基于粗波分复用存储扩展系统性能的因素,采用OPNET仿真软件建立基于粗波分复用的存储扩展仿真模型,对扩展距离、信用值、FC帧大小以及链路带宽等因素对存储扩展性能的影响进行仿真分析。结果表明,随着扩展距离、链路带宽和FC帧长的增加,需要相应用于流量控制的信用值,才能维持存储扩展系统的高性能。

Abstract: In order to analyze influential factors of performance of storage extension based on Coarse Wavelength Division Multiplexing (CWDM), this paper prestents simulation environment by using OPNET software to study how distance, credit, FC frame size or bandwidth of extension link impact the performance of stroage extension based on CWDM. Simulation results show that with the increase of distance, credit, FC frame size or bandwidth of link, more credits need to be allocated to sustain high throughput.

Key words: Coarse Wavelength Division Multiplexing(CWDM), disaster recovery, performance simulation
