The invention discloses a
data center, and belongs to the technical field of
data center process
layout. According to the scheme, a cluster unit of the
data center is of a three-layer annular structure and is divided into a plurality of modules in the radial direction; a spine switch is deployed on the first annular layer, GPU
server cabinets are deployed on the second annular layer and the third annular layer, and a leaf switch is further deployed on the second annular layer; the distances between the
layers and the positions of the spine switches and the leaf switches are reasonably set, so that the distances between the GPU servers and the leaf switches in the modules, between the leaf switches and the spine switches and between the spine switches in the cluster units are all smaller than 5 meters, the GPU servers and the leaf switches are connected through
copper cables, the leaf switches and the spine switches are connected through
copper cables, and the spine switches are connected through
copper cables. According to the scheme, through reasonable
layout, the reliability of the network is improved, and the
network delay, the networking cost and the
power consumption are reduced.
