PRS200磁盘阵列是美国 GVG 公司 PDR200的外接阵列,它由20个9G 硬盘组成,每5个硬盘组成一组RAI03,总有效容量为144G.若存储9万字节/场的图像,可存约9小时节目,而这个阵列需9万美元.我们使用通用的 SCSI 阵列5960RN 代替 PRS200,选用稀捷36G 硬盘,每8个硬盘组成一个 RAID5,总有效容量为252G,可存约15小时节目.配置4个5960RN 阵列仅需40多万人民币,可存约60小时的节目,这次扩充阵列后,能满足我台两套节目全天播
PRS200 disk array is an external array of GVG’s PDR200 in the United States. It consists of 20 9G hard disks and each of them has a total capacity of 144G. If you store 90,000 bytes / field, you can save 9 Hour program, and this array needs 90,000 US dollars. We use the common SCSI array 5960RN instead of PRS200, the choice of thin Jie 36G hard drive, hard disk each consisting of a RAID5, the total effective capacity of 252G, save about 15 hours. A 5960RN array only needs more than 400000 yuan, about 60 hours of programs can be saved, this expansion of the array, I can meet two sets of programs broadcast all day
