ARISTA BASICS
This is Arista’s operating system that runs on ALL of their switches.
EOS (Extensible Operating System)
Cisco’s data center switching platform that Arista most directly competes against.
Nexus 9000
The three-year financial model you build to show a customer that Arista’s lower operational costs beat the upfront price difference.
TCO (Total Cost of Ownership) Model
Arista only sells to giant hyperscale cloud providers like Amazon and Microsoft.
FALSE — Arista sells broadly: enterprise, financial services, healthcare, media, and more.
Arista’s management and automation platform that gives you network-wide visibility and change control.
CloudVision (CVP)
Cisco’s campus switching line that Arista competes against at the enterprise edge.
Catalyst 9000
The two roles you need in any Arista deal — one who signs the check, and one who recommends the technology.
Economic Buyer & Technical Champion
CloudVision can manage both Arista and third-party switches.
FALSE — CloudVision manages Arista devices. Multi-vendor is not its primary design. Can have visibility, but limited.
Arista is best known for dominating this type of network environment — high-speed, low-latency switching for servers.
Data Center / Cloud Networking
Arista has ONE operating system. Cisco has several — name two of them.
IOS, NX-OS, IOS XE, IOS XR (any 2)
The best way to get a foot in the door at an account with no active network project — propose this low-risk first step.
Proof of Value / Pilot / Lab Trial
Arista’s EOS supports Python scripting natively on the switch itself.
TRUE — EOS has a built-in Python interpreter allowing on-box automation.
The big competitive advantage of having a single EOS image across all platforms — fewer OS versions means less of this for IT teams.
Training / Operational Complexity
This Cisco controller for campus networking is the comparable product to Arista CloudVision.
Cisco DNA Center / Catalyst Center
This vertical in MA has exploding infrastructure needs due to AI and genomics workloads — a top Arista prospect.
Biotech / Life Sciences
The best time to approach a Cisco customer about Arista is BEFORE their hardware hits End of Sale.
TRUE — You want to be in the conversation before they re-up with Cisco.
Arista’s API that lets customers automate and program the network using standard tools like Python and REST-like interface.
eAPI (Extensible API)
When a Cisco product hits this milestone, the clock starts ticking on support — making it your best entry point for displacement.
End of Sale (EoS) / End of Life (EoL)
Arista’s primary financial argument isn’t just cheaper hardware — it’s savings in this area, because one OS means less training and fewer outages.
Operational Expenditure (OpEx) / Labor Savings
Arista was co-founded by people with ties to Cisco’s early history.
TRUE — Andy Bechtolsheim and David Cheriton were early Cisco investors. CEO Jayshree Ullal is a former Cisco SVP.
