Dear Big Switch Networks Customers and Partners,

We have some exciting news that I am pleased to share with you. Arista Networks (NYSE:ANET), an industry leader in software driven cloud networking solutions for large datacenter and computing environments, today announced that it has acquired Big Switch Networks.

We would like to thank you for being a valued Big Switch customer and for the faith you have put into our team and our products. We are incredibly proud about the technology we have built to address complexities related to networking and monitoring. Each of you have played an important part of our journey and we thank you.

Last year, Arista announced multi-cloud networking, designed to address transitional changes as enterprises move to hyper-converged private cloud as well as hybrid cloud. Designed to bring deep visibility, operational simplification and modern cloud principles to the enterprise hybrid cloud, Arista extends this architecture with the addition of Big Switch by enabling security monitoring, predictive analytics and automated HCI interconnect at enterprise scale.

The team at Big Switch looks forward to working with the Arista team to deliver new visibility and analytics solutions for high performance network monitoring. Big Switch’s transformative solution for next-generation Network Packet Broker (NPB) and HCI interconnect have brought radical cloud-like simplification and scale-out deployments. Our recent positioning as a Visionary in the Gartner 2018 Magic Quadrant for Data Center Networking validates the powerful technology that we have developed.

Arista Perspective

The Arista team is very enthusiastic and believes synergy between the two companies is a compelling combination for enterprise customers. “We are excited about Arista's acquisition of Big Switch and its significance to Arista's cloud networking and monitoring vision. We welcome the Big Switch Networks employees to the Arista family” stated President and CEO of Arista Networks Jayshree Ullal.

In terms of day-to-day business with our valued customers and partners, there will be no immediate changes. Both Big Switch products, Big Cloud Fabric (BCF), Big Monitoring Fabric (BMF), continue to be developed & supported by Arista and offered through our OEM and resell partners. As Big Switch becomes part of Arista, we will be integrating our sales and partner personnel into Arista. You may be introduced to some new people that will support you going forward. If any of these personnel changes affect you, we will let you know the details very soon.
