The Founders' Circle
This hardware legend designed the first Sun workstation and famously wrote Google’s first $100,000 check.
Who is Andy Bechtolsheim?
This is the full name of Arista’s core software, the "Extensible Operating System."
What is EOS?
Arista famously runs this many automated software tests every single day to ensure reliability.
What is 250,000+?
This Arista platform provides a "single pane of glass" for managing Data Center, Campus, and Cloud networks.
What is CloudVision?
Arista’s security philosophy, which assumes no user or device should be trusted by default, is known as this.
What is Zero Trust?
Before becoming Arista’s CEO, she led Cisco’s multi-billion dollar switching business for 15 years.
Who is Jayshree Ullal?
Arista switches run on an unmodified version of this open-source kernel, making it easy for customers to run 3rd party agents like Splunk or Wireshark directly on the switch.
What is Linux?
In 2024/2025, Arista reached this "world-class" Net Promoter Score (NPS), placing them in the top 1% of global companies.
What is +93?
This standard protocol is used for network virtualization and is a key component of Arista’s cloud-scale designs.
What is VXLAN?
This Arista technology allows for "Micro-segmentation" to isolate threats without needing a complex firewall at every port.
What is MSS (Multi-Domain Segmentation)?
Arista's "Employee #1" and current CTO, he is the primary architect of the EOS operating system.
Who is Ken Duda?
This "centralized state" database architecture allows EOS to recover from process failures without a system reboot.
What is NetDB (Network Database)?
This common abbreviation refers to the unique ID assigned to security vulnerabilities that Arista aims to minimize via rigorous testing.
What is a CVE (Common Vulnerabilities and Exposures)?
Arista is a founding member of this consortium, designed to create an open standard for high-performance AI backend networking.
What is the Ultra Ethernet Consortium (UEC)?
Arista expanded into this market to challenge the "Wired and Wireless" dominance of Aruba and Cisco.
What is the Cognitive Campus?
This Stanford Professor and Arista co-founder is known for his work in distributed systems and being a "billionaire professor."
Who is David Cheriton?
Arista's software allows for this type of upgrade, which enables updating a switch without dropping a single packet of traffic.
What is a "Smart System Upgrade" (or Hitless Upgrade)?
Arista's high-speed switches are often measured by this, the time it takes for a packet to travel from one port to another, often in nanoseconds.
What is Latency?
Arista's high-memory switches use these "deep" components to prevent data loss during heavy bursts of AI or "incast" traffic.
What are Virtual Output Queues (VOQs) or Deep Buffers?
This cloud-based Wi-Fi management system was part of the Mojo Networks acquisition.
What is Arista Cognitive Wi-Fi?
In 1995, Bechtolsheim and Cheriton founded this Gigabit Ethernet company, which was later acquired by Cisco.
What is Granite Systems?
Arista famously uses a "single" one of these for its entire product line, unlike competitors who have different software for every hardware family.
What is a Single Binary Image?
This was the approximate year Arista went public (IPO) on the New York Stock Exchange.
What is 2014?
This specific Arista routing architecture replaces legacy complex protocols with a simpler, cloud-scale approach.
What is Cognitive Adjacency (or Universal Cloud Network)?
This feature allows Arista switches to "snapshot" the entire state of the network for retrospective security analysis.
What is DANZ (Data Analyzer)?
