We use Arista 7000 series switches at two levels. First, we use two 7304's as our core distributed across two data centers. Second, we user 7050T's as our data center top of rack switching.

Pros and Cons

The 7304's along side our core network design has provided 100% uptime during the 5 years of deployment.
The multi-chassis LAG has provided near 100% connectivity to the distribution and access switches.
Very low maintenance attention is needed.

The 7304's lack a graceful non-intrusive upgrade method even though they are dual supervisor.
I would like to see more integration with Aruba's ClearPass and Airwave products.

Likelihood to Recommend

Core and data center applications are the strengths of Arista products. The distribution layer is also a good fit. For the access layer, it would be more of a niche product.

Return on Investment

The Arista 7000 series met or exceed our data center switching and routing needs.
It provided a more cost effective alternative to other products we were considering.
Implementation was quick and easy due to the simple standards-based configuration.

Alternatives Considered

Cisco Catalyst, Cisco Nexus and Aruba Networks Wireless

I have used the Catalyst 6500 series in the past. From my point of view, the Arista surpasses the Catalyst on just about every front. Originally we were planning on implementing the Nexus 7000/7700 series switches for our core. Though a little more feature rich, it did not provide features we needed that the Arista did. The Nexus also was a confusing and complex platform to work with. Also, the Nexus was a significantly more expensive solution. Although very happy with the Arista switches we may evaluate the Aruba HPE 8400 chassis-based switches along with Arista switches in the future.
