在计算能力与传输能力两个环节上,传统SAN存在很多先天的弱点。基于总线与交换机架构的SAN系统会因为计算能力与传输能力的配合瓶颈,不适合某些高性能的应用。目前市场上的很多SAN产品都存在这样的问題:在产品白皮书中宣称的性能非常优越,小规模的实测数据也不错,但在实际的安装运行过程中特別是大规模应用中,却只能发挥其标称性能的20％～30％,具体体现为性能曲线的突然下降。针对传统SAN传輸能力不足的瓶颈,DataDirect Networks公司提出了
In the two aspects of computing power and transmission capacity, the traditional SAN has many inherent weaknesses. SAN system based on bus and switch architecture will not be suitable for some high-performance applications due to the bottleneck of computing power and transmission capacity. Many SAN products on the market today have such problems: the performance claimed in the product white paper is superior and the small-scale measured data are good, but they can only be used in actual installation and operation, especially in large-scale applications Its nominal performance of 20% to 30%, embodied in a sudden drop in performance curve. DataDirect Networks has proposed a bottleneck that is not enough for traditional SAN transport
