Validating datacenters at scale
Proceedings of the ACM Special Interest Group on Data Communication, 2019We describe our experiences using formal methods and automated theorem proving for network operation at scale. The experiences are based on developing and applying the SecGuru and RCDC (Reality Checker for Data Centers) tools in Azure. SecGuru has been used since 2013 and thus, is arguably a pioneering industrial deployment of network verification ...

The stellar transformation: From interconnection networks to datacenter networks
Computer Networks, 2017 The first dual-port server-centric datacenter network, FiConn, was introduced in 2009 and there are several others now in existence; however, the pool of topologies to choose from remains small.

Practical Packet Deflection in Datacenters
Proceedings of the ACM on Networking, 2023Bursts, sudden surges in network utilization, are a significant root cause of packet loss and high latency in datacenters. Packet deflection, re-routing packets that arrive at a local hotspot to neighboring switches, is shown to be a potent countermeasure against bursts.

Energy proportional datacenter networks
Computer Architecture News, 2010Numerous studies have shown that datacenter computers rarely operate at full utilization, leading to a number of proposals for creating servers that are energy proportional with respect to the computation that they are performing.

Proceedings of the 29th ACM on International Conference on Supercomputing, 2015
Over the last 10+ years, large datacenters have benefited from computer technology and physical infrastructure advances that substantially improved their efficiency. However, there is still much room for improvement, as the datacenters' computational resources are often poorly utilized and technology advances are starting to falter.

Optical Components for Datacenters
Optical Fiber Communication Conference, 2017• There is currently little near-term incentive for large-scale datacenter operators to change the way the build datacenters. • Future datacenters will becoming increasingly difficult once the data rate for a single switch chip saturates. — When this will occur is subject to debate.

Silicon Photonics for the Datacenter
Optical Fiber Communication Conference, 2015To fully benefit from silicon photonics technology at the system-level, novel electro-optical assembly techniques are required enabling a close integration with the processor or switch chip. Optical coupling and signal distribution options are discussed.

SCautz: a high performance and fault-tolerant datacenter network for modular datacenters
Science China Information Sciences, 2012Modular datacenters (MDCs) use shipping containers, encapsulating thousands of servers, as large pluggable building blocks for mega datacenters. The MDC’s “service-free” model poses stricter demand on fault-tolerance of the modular datacenter network (MDCN).
