Arista 7000 series vs. Cisco 1000 Series Connected Grid Routers (CGR 1000)

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.

This tool is suitable for smart grid environments where remote monitoring and control is required, and arguably it may be a little less appropriate for organizations with limited resources for initial implementation and configuration. But in general it can help improve the efficiency of the electrical grid. Its advanced security, scalability and analytical capabilities distinguish it from other similar programs.

• 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.

• Segments the network.
• Provides security through the use of Access Control Lists.
• Makes routing decisions using routing protocols such as OSPF, RIP, BGP etc ...
• Provides fault tolerance.

Incentivized

• 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.

Incentivized

• Improve integration with other systems
• Some advanced features may require complex configuration
• Some functions take a long time

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.

Cisco and HPE Routers are comparable products. Both do the job well without many differences. I would say HP Routers are easier to configure but come with a small performance hit compared to Cisco routers of the same size/scope. Cisco has the brand recognition and many more certified professionals using them though.

• 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.

Incentivized

• Improvement in operational efficiency
• Reduced downtime
• Greater reliability in the electrical network
