Data CenterIn general, administrators will first apologize for messy cabling. Wiring is simple-connecting servers to network switches with cables. However, cable placement like "noodles" affects the cabinet space utilization and appearance. chaotic scenes are like the tangle of many snakes, which cannot be clarified. We understand how things have evolved so far, but we cannot determine the root cause of this result. Is such chaos the result of technol
