Abstract: A wireless server-to-server datacenter network architecture uses wireless links to eliminate the need for power-hungry switching fabric of traditional fat-tree based datacenter networks. The server-to-server wireless datacenter network (S2S-WiDCN) requires Line-of-Sight (LoS) between servers to establish direct communication links. Utilizing this LoS links, a horizontal-first routing algorithm is developed which, will establish fast communication links between any pair of communicating servers in the data center. The wireless links can be realized in millimeter-wave (such as 30, 60, 120 GHz) or THz (such as 300 GHz) frequency bands. The use of antenna-arrays to create beam-steering towards communicating servers is necessary to establish the direct server-to-server links. In the presence of an obstruction such as an IT technician, the LoS between communicating servers may be blocked. To address this issue, an obstruction-aware adaptive routing algorithm for the S2S-WiDCN is proposed. Alternatively, the wireless links can be realized with FSO. The performance of such a wireless data center is better than that of conventional tree-based wired data centers while its power consumption is significantly lower than that of the conventional data center network.
