Powerful servers combined with high-performance storage and applications that use increasingly complex computations are causing data bandwidth requirements to spiral upward. Whether looking at price-to-performance or energy-to-performance, these systems offer superior performance, power and space, reducing capital and operating expenses and providing the best return-on-investment. These systems are the industry's most cost-effective building blocks for embedded systems and storage with a need for low port density systems. These switches deliver 7.2 billion packets-per-second (Bpps), or 390 million pps per port. The Journal of Supercomputing Springer Journals Mellanox QM8700/QM8790 switch systems provide the highest performing fabric solution in a 1U form factor by delivering up to 16Tb/s of non-blocking bandwidth with sub 130ns port-to-port latency. By comparing with the existing data center network topologies, we show that HHS is a promising candidate for large-scale data centers because of its ability to achieve a desirable trade-off between performance and cost, without introducing any overheads on servers.

Our simulation results show that the HHS network offers low latency and high throughput under different workloads. We also present a multipath routing algorithm for HHS. The proposed topology can accommodate a large number of servers with small network diameter, low cost and high bisection bandwidth. HHS is a symmetric multi-dimensional topology, in which switches form a Hoffman–Singleton graph in each dimension. In this paper, we propose a novel switch-centric data center network topology called Hyper Hoffman–Singleton (HHS). Although the current switch-centric network topologies have high bisection bandwidth, they bear the disadvantage of high network cost.
