Abstract
Traditional data centers, which are based on wired networks, have been installed many years. However, they often suffer from high cost of construction and management. The data-intensive workloads motivate modern data centers to utilize higher-bandwidth networks like 10 Gb Ethernet (10 GbE). Traditional wired data centers, suffering from complex wiring and management, can not always satisfy this requirement. Wireless data centers have some advantages such as economical installing and no worry about wiring. This paper proposes a new completely wireless data center, which has good performance and high fault tolerance to the network failures. We propose a novel data center design including intra-rack and inter-rack architectures. Especially, inter-rack data transmission can be finished by one hop when we transmit data via the ceiling. Data center, built with this methodology, is significantly convenient to be deployed and managed, which avoids the complex wiring and too much material cost. Extensive simulations have been conducted to verify the effectiveness of our proposal. Our novel design of wireless data center outperforms Cayley data center on bandwidth and good fault tolerance as well as reducing hotspot in the network.
