Featured Reviews

Dibyendu Das - PeerSpot reviewer
Director at a tech company with 11-50 employees
Ultra-low latency networking has delivered reliable video workflows and critical operations
The support of Arista Networks Platform is quite complex; it is not very easy to configure. It needs a lot of network expertise for token sheddings and different kinds of configurations. It is very difficult to configure because Arista Networks Platform does not have a flexible GUI like Huawei or Netgear; everything is a very CLI kind of mainframe architecture. Scalability at every single step has a huge upgrade cost which is required for port mapping, connectivity, and transceivers certified by Arista Networks Platform, then the fabric upgrades from a software firmware level. Arista Networks Platform should improve commercial aspects to be affordable. There is no path for growth with a perfect score because the focus is more on reducing costs globally.

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 features of Arista include low latency, scalability, and sustainability of the products."
"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."
"The solution offers a lot of features and we were able to organize our network around them, and the configuration capabilities were good."
"Great latency (bundled with great L1/L2/L3 features) depending on platforms."
"The most valuable feature is the Linux shell, which is useful for troubleshooting or capturing traffic."
"Arista Networks Platform's features have significantly improved network visibility and operational efficiency."
"Arista Networks Platform is comfortable, easy to deploy, and easy to manage, with non-blocking technology. Additionally, it has a useful CloudVision platform and automation capabilities."
"What we like most is its performance to price ratio."
"It also allows for frequent manipulation or configuration."
"It is a highly scalable solution, and we mainly use it for 100 gig connectivity."
 

Cons

"They need to enhance their code and their EOS. They need to improve some security features, and there are quite a number of bugs in their system."
"The product is fairly expensive. It's not a cheap option."
"The community is good but is not good enough. It still needs to grow more."
"The product fails to offer functions related to cloud orchestration, making it in areas where improvements are required."
"A smoother transition between ISPs during failover would improve the user experience by reducing unnecessary notifications and interruptions."
"The overall price of the Arista Networks Platform is expensive. It should be reduced."
"For my particular use, the only potential improvement I see is in power consumption."
"Arista is very expensive."
"It would be good if they added a redundant routing engine."
 

Pricing and Cost Advice

"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."
"It is pretty pricey for a networking platform. It is on par with Cisco."
"The price of the Arista Networks Platform could be less expensive for the hardware and license."
"Arista Networks Platform was cheaper than Cisco. I have heard that the product is affordable for enterprise-sized companies."
"Network devices are generally expensive. However, during the evaluation, Arista was the most inexpensive vendor."
"If one is cheap and ten is expensive, I rate the product price as seven out of ten."
"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."
"I rate the product price a seven on a scale of one to ten where ten is high price and one is low price."
