“The Arista EOS is absolutely critical as it allows us to embed our custom software in each switch to detect and block issues like denial of service attacks and other threats in the most efficient manner.”

Joakim Sundberg, co-founder
.Baffin Bay Networks

“I really took a risk moving off the incumbent vendor, but it has more than paid off. The network is so stable I haven’t had to touch the network much in 3 years.”

Eric Perkins, Senior Network Engineer
.Littleton Regional Healthcare

“We weren’t just looking for a piece of hardware, we were looking for a partner. The impact of this project will affect not just us but research projects around the world and we were embarking on a bit of a journey of discovery.”

Dr Peter Clapham, Informatics Support Group Team Leader
.The Wellcome Trust Sanger Institute selects Arista for innovative cloud-based infrastructure as a service platform to aid scientific breakthroughs

“We effectively process more transactions than the London Stock Exchanges combined and our development teams are continually working on a variety of projects that require our infrastructure to deliver both high performance and the ability to rapidly scale.”

Richard Haigh, Head of Delivery Enablement
.Paddy Power Betfair selects Arista Networks as the critical network layer in its transition to an Infrastructure-as-a-Service and DevOps focused environment

“We have the Arista platforms running operationally now for nearly five years and the performance along with the integration into our SDN architecture is phenomenal, but what is just as important is our relationship with the Arista team – this goes beyond just support, by providing us access to some incredibly knowledgeable people has allowed us to develop new features that have added some unique capabilities to the way we manage our cloud.”

Edwin Beekman, a Mission Critical Engineer
.Schuberg Philis selects Arista for its Mission Critical Cloud as part of a successful and ongoing journey to meet its 100% principle

“We selected Arista for its known performance and robustness. Being a proven technology in combination with the fact that it runs Linux provides us the flexibility we need in a switch platform supporting a fast changing technology such as OpenStack.”

Tjebbe de Winter, co-founder of Cyso
.Cyso selects Arista as critical foundation for low cost, reliable and scalable public cloud service.

"The decision to go with Arista also gave us an opportunity to revaluate our architecture and start to take advantage of extensibility features within the platform such as buffer monitoring, that offer us more visibility over traffic flow, and to take proactive capacity planning measures to avoid any future issues.”

Aaron White, Global Head of Networks for Options
.Options selects Arista to deliver ultra-low latency access to a diverse range of order execution and broker services for over 200 financial services firms.

"We looked at a number of options and only Arista’s implementation of universal spine plus FlexRoute offers us the performance benefits of deploying a traditional routing platform with cost savings and flexibility of a switching architecture. In terms of performance and reliability, the Arista solution has been faultless and integrated seamlessly with the other elements within our plant with enough density and headroom to allow us to scale to meet new business demands”

Gabriele Ubertini, Head of Technology Research and Engineering
.Sky Italia selects Arista for innovative transition to SDI over IP networking while delivering broadcast grade performance and resiliency.

“The architecture is designed to cope well with unanticipated issues and we have worked with a fantastically responsive team at Arista to do things which would normally be incredibly challenging with monolithic network operating system architecture - and crucially, while delivering the highest levels of performance and availability for the network.”

Oliver Gorwits, Head of Networks and Computer Security for ECMWF
.Arista Selected for ECMWF Critical and Extensible Network Infrastructure

“The advantage of the solution offered by Arista is a combination of MLAG functionality with very low packet latency, which is a very important feature when it comes to distributed calculations.”

Adam Padée, Head of the Computing Infrastructure Team at the Centre
.National Centre for Nuclear Research

“The Arista switches will allow us to work smarter not harder, and staff and students will certainly notice and benefit from the performance hike delivered by the upgrade.”

Sean Ashford, The University of Winchester’s Network and Systems Manager

“I’ve been building networks at AWE for 27 years. This project has been really exciting as it’s the first time we’ve set up a whole new network from scratch and implemented the latest state of the art equipment. Based on the commitments made to the business 12 months ago, working with Arista has meant we’ve achieved what we set out to do. Our requirements have certainly been met.”

Neil McMahon, Atomic Weapons Establishment’s Networking Manager for HPC
.AWE Case Study

"For the cost, density and performance we were looking for, we could find no other solution that got close to the level of the Arista switches. The move to Arista has led to a 6 to 8 times increase in throughput with a latency reduction."

Christian Marnitz, Head of Technology, Picturemaxx
.Picturemaxx Case Study

"I would say that Arista has the best technical support in the business. We got nothing but highly knowledgeable people at initial contact, and an excellent and honest sales staff, with no gray area or misunderstandings. It was an excellent decision to turn our network into an Arista data center."

Len Gedeon, Information Technical Consultant, Medical Mutual

"Cloudera Enterprise, the core of an enterprise data hub, gives our customers access to all their data whether structured or unstructured. It's the foundation for the next generation of data management infrastructure, and provides insights that haven't been possible until now. Arista's Map Reduce Tracer provides similar insights to network administrators in understanding network performance and big data workloads across a variety of large data center and computing environments offering us high availability, which is critical for our success."

Tor Amundson, Network Engineer, Cloudera

"NPL holds the time source of highest accuracy in the UK, participating in the UTC definition. NPL employs Arista 7150S high precision Ethernet switches to deliver its NPLTime® service, which offers a certified time distribution for the financial sector. NPL employs PTP across a network of Arista 7150S, selected for the accuracy of its hardware-based timestamping and OCXO, providing highly precise and stable PTP time distribution, hence preserving the highest precision timing towards the organizations and customers that receive a certified precise time signal, directly traceable to UTC and independent of GPS."

Dr. Leon Lobo, Business Development Manager (Time and Frequency), National Physical Laboratory

"The network is critical to maintaining the services our customers depend on. With Arista EOS and the Arista 7300 platform, we will be able to automate and program our network, ensuring high availability and uptime while also reducing our operational costs."
