为了进一步提高光盘阵列的性能，在分析单个光盘驱动器数据传输过程的基础上，建立了光盘阵列数据传输的理论模型。从理论和实验两个方面分析了传输的数据长度、ＳＣＳＩ总线速度与光驱速度之比、数据分块大小对光盘阵列数据传输率的影响程度，并提出了优化设计方法。实验表明，通过选择合适的应用背景、减少总线冲突等优化设计方法，可使光盘阵列数据传输的实测并行度提高到４．２３６， 接近理想值。
In order to further improve the performance of the optical disc array, a theoretical model of optical disc array data transmission is established on the basis of analyzing the data transmission process of a single optical disc drive. Analyzed the length of data transmission, the ratio of SCSI bus speed to optical drive speed and the influence of data block size on the data transmission rate of optical disk array from two aspects of theory and experiment, and put forward the optimal design method. Experiments show that by selecting suitable application background and reducing bus conflict, the actual measurement parallelism of data transmission can be increased to 4.236, close to the ideal value.
