Automation and visibility have simplified data center operations and improved network control
I see some areas for improvement, particularly with pricing. I think that not all features that are needed are already in Arista. AI power is required nowadays. AI would be needed for understanding data traffic flowing in my network. Sometimes I have a vision of what data traffic is flowing in my network and I want to capture that data. Using AI, I can understand how my entire organization operates and what kind of applications are being used, what the peak times are, where there is a bottleneck if any exists. This kind of report should automatically generate and provide clear-cut visibility.

Has consistently supported high availability with reliable performance and minimal disruption
Cisco Nexus 9000 Series and the routers are good, but the FMC or FTDs still need some improvement. We have Palo Alto firewalls and Next-Generation Firewalls in our environment. In comparison to the main firewall, we moved from Cisco FTDs to Palo Alto. We still have FTDs in our environment, but the majority of the firewalls have been moved to Palo Alto. They are more user-friendly, give more visibility, and are more efficient. The performance is better than Cisco. With the new features, Cisco is having some improvement for the FTD. I am currently evaluating the FTDs. The new version has better features like the encrypted visibility engine and user-based changes in FMCs, and other things are quite useful for us. FTDs do have limitations and other issues. We communicated that limitation and feature support to the Cisco account manager. We do have support for the devices. We currently have a weekly call with Cisco and they are making progress regarding new versions of the FMCs and introducing new features. The performance of deployment has improved quite a bit compared to four or five years ago.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature is the Linux shell, which is useful for troubleshooting or capturing traffic."
"The best part is the single operating system that they have. Regardless of your model, it's the same operating system functioning across the board, which means you don't have to worry about backward compatibilities between your older switches and the new ones that you deploy."
"It's an extremely reliable platform for the network switches we use."
"Arista Networks Platform has a feature that helps with monitoring and management."
"Great latency (bundled with great L1/L2/L3 features) depending on platforms."
"We are always surprised about the proficiency of the speed of the technical support."
"The product's initial setup phase was straightforward."
"The most valuable features of the Arista Networks Platform are the EVPN and VXLAN. It has comprehensive features."
"Cisco Nexus 9000 Series is quite a complex machine, but we are using a very simple configuration with basic Nexus switching, and we don't have many issues with Cisco Nexus 9000 Series at the moment in our present infrastructure."
"Performance has been great with no abnormal behaviors detected, and the network remains stable even in failover scenarios, supporting vast environments with high availability."
"Cisco Nexus 9000 Series is very durable and very reliable, and there has never been any issue with it."
"RealPresence works effectively."
 

Cons

"I see some areas for improvement, particularly with pricing."
"Arista Networks Platform should focus on improving the compatibility or integration with Cisco solutions."
"I know that Arista is more expensive than the Catalyst or Nexus."
"The documentation did not explain that we could not vary the speed between ports that are in the same block. For example, we cannot have 1G and 10G on the neighboring ports; all four ports have to be 1G or 10G, which was very annoying for us when we realized that we needed to change the configuration and the cabling that we had already prepared."
"The CVP management platform needs to be improved."
"The community is good but is not good enough. It still needs to grow more."
"Something that you will often hear about Arista products is that the price is a bit too high and, like with Cisco, we sometimes have problems with our customers because of its pricing."
"Arista Networks is currently less popular as they were initially more focused on data centers than campus networks. They should expand further into campus networks."
"Cost-wise, Cisco Nexus 9000 Series is very expensive."
"We find that Cisco has been left behind by the other vendors. The other vendors have adopted new technology, and we find Cisco lagging behind."
"The SFP modules we are using have had issues. We have Cisco modules, but they frequently heat up or there are packet error issues."
 

Pricing and Cost Advice

"There is an annual license required to use the Arista Networks Platform."
"I rate the product price a seven on a scale of one to ten where ten is high price and one is low price."
"The price of the Arista Networks Platform could be less expensive for the hardware and license."
"Network devices are generally expensive. However, during the evaluation, Arista was the most inexpensive vendor."
"The customer price for an Arista router is approximately $7,000 USD, while Cisco's is around $18,000."
"I remember that when our customers were offered the Arista Networks Platform, they used a checklist to compare the prices between Arista and Cisco for their requirements, and found that the prices were almost the same."
"Specific tools definitely require a license for the subscription. But we are not using these tools in our environment. In terms of licensing, you need to spend approximately $10,000 per month."
"Arista is very expensive. Not everybody is in a position to spend $70,000 to $80,000 for one switch."
