Switch Recommendation for my Infrastructure

So, I have a PA850 on the perimeter, and downstream into my datacenter (4 Hosts, 1 SAN 100 TB,...) our existing virtual to storage infrastructure is utilizing a Dell N4032F 10g, we wanted an easy backup solution in the event of a device failure.

One of my partners is quoting me about $10,000 (with modules + cables) for the same 4032f switch while just as a second opinion (typically don't do that) another partner was asking me to think beyond Dell's networking and look at Arista. Not familiar with them at all. But when i checked, he might have a point - I am still learning my work in parts, so any input will help here.
