Great latency (bundled with great L1/L2/L3 features) depending on platforms.
Vice President, Network Engineering at a financial services firm with 201-500 employees
Easy to work with, has good load latency, and is slightly less expensive than Cisco
Pros and Cons
- "The solution has good load latency. They're the market leader in this aspect right now."
- "The solution needs to accommodate new features."
What is most valuable?
What needs improvement?
There is a lot of room for improvement within the solution. Any product, however, can improve. No product is perfect.
The solution needs to accommodate new features.
I have personally made some recommendations in the past and hope to see this implemented in their product line.
I think there is a need for improvement in the area of their VXLAN/EVPN capability but their current solution is great regardless but may be not very scalable for a global deployment.
For how long have I used the solution?
I've been using the solution for three years at this point. It's been a while.
What do I think about the scalability of the solution?
Again, this depend on the solution and requirement. Arista has different models that can fit into small, medium and large datacenter. Scalability is a factor in any design for expansion.

Arista and Cisco are comparatively the same or Cisco a bit more expensive depending on the platforms. However, I like Arista's licensing approach. Cisco licensing could be made simpler.

Every industry is different, so what is going to work for a service provider might not really work for an enterprise environment. Requirement is key in any design proposal.
Vendor/Platforms should tailored to the requirements and solutions.
