Arista Networks: Why the Modern Network No Longer Looks Like It Used to
EOS, CloudVision, Deep Buffers, and open standards
When we at Aixia discuss infrastructure with our customers, the network often takes center stage as the critical nervous system of the business. But the truth is that many companies are still struggling with network architectures designed for a bygone era. Traditional solutions are often inflexible, difficult to automate, and subject to proprietary lock-ins.
This is where Arista Networks comes into the picture. Arista hasn’t just built faster switches; it has redefined what a network should be in an era marked by cloud services, AI, and massive amounts of data. Here are the reasons why Arista is the most interesting player on the market right now.
EOS – An Operating System for the Entire Portfolio
The single biggest advantage of Arista is its operating system, EOS (Extensible Operating System). Unlike many competitors, Arista runs the exact same binary image on all of its devices.
Consistency: Whether it’s a switch in a small office or a backbone switch in a data center, the logic and commands are the same.
Programmability: EOS is built on an open-source Linux kernel. Network engineers can use Python and Ansible to automate the network.
Stability: The state-sharing architecture separates the network protocols from the operating system. If a process fails, it is restarted without taking down the entire switch.
CloudVision: Complete Transparency and Automation
Managing a network via the CLI is an outdated approach. Arista’s solution is CloudVision —network-wide automation and telemetry.
Instead of just SNMP alerts, Arista devices stream data in real time to CloudVision. This creates a digital twin of your entire network. You can go back in time, identify bottlenecks before they become problems, and roll out configuration changes to hundreds of devices with the push of a button.
Designed for AI and Storage: Deep Buffers
One aspect that makes Arista particularly interesting to Aixia’s customers—AI and high-performance storage—is Deep Buffers.
When running heavy AI workloads or NVMe-over-Fabrics, short but intense traffic spikes occur. Traditional switches drop packets and introduce latency. Arista handles these micro-bursts and ensures a consistent data flow.
Open Standards Over Lock-in
Arista is based on open standards such as VXLAN and EVPN. This gives you, the customer, freedom—you own your architecture and aren’t tied to a vendor’s roadmap.
🔧 Why choose Arista through Aixia?
At Aixia, we have in-depth technical expertise across Arista’s entire portfolio. We don’t view the network as an isolated entity, but rather as an integral part of your overall infrastructure.
- Easier to operate thanks to EOS and CloudVision
- More reliable with the market’s most stable software architecture
- Ready for the future, whether it’s 400G or extremely demanding AI environments
Is your network a bottleneck or an enabler? At Aixia, we’d be happy to help you evaluate how Arista can modernize your infrastructure. Contact us for a demo of CloudVision.
