Each node supports 24 hard disks of 3 rows and 8 columns. In addition, the nodes are independent, when one node needs to be operated and maintained, the node can be directly pulled out of the system, the backflow preventing structure (baffle) above the node falls down at the moment, the channel is blocked, wind is ensured to flow through other nodes, and the temperature requirement required by normal work of hard disks of other nodes is met. The design cost of a guide rail, a cable, a wire arrangement frame and the like is saved in the hot maintenance data design of the cold storage type server, so that the investment and the operation cost of a terminal client server can be greatly reduced; the partitioned design also provides great convenience for hard disk maintenance and data recovery.
