A row-level backup disaster recovery scheme is proposed in this paper for solving the defects of rack-level cooling system in data centers. The cooling performance is compared with traditional room-level backup disaster tolerant scheme using computer fluid dynamics (CFD) simulation software. The simulation results show that the cooling effect of IT equipment under row-level cooling backup disaster tolerant scheme is significantly better than that of room-level backup scheme. The devices can work in normal temperature range when one air conditioner fails in row-level backup scheme, while hot spots will occur in row level backup scheme.
