Arista Network Advantage: Lower TCO with Power-Efficient Platforms

The data centers contribute 4-5% of the world’s total electricity usage.  This signifies the role it plays in GHG emissions and the worrying climate changes.  It is important that organizations consider energy-efficient systems for their critical IT requirement to meet their business objectives. And the same time reduces their carbon footprint and gets the benefit of reduced OPEX and TCO.

As organizations looking for ways to reduce their environmental impact and lower their energy costs. One way to do this is to invest in energy-efficient data center solutions. These solutions can help to reduce the amount of power that data centers consume, which can lead to significant savings. This blog compares the usual top-of-the-rack (ToR) data center switch models from Arista Network and Cisco Systems. And compares the power efficiency based on the numbers published in their corresponding switches datasheets

ToR Switches Comparison

As you can see from the table, Arista Network switches offer advantages over Cisco switches. Arista switches typically have lower power consumption, higher throughput, and lower latency. This can make them a more cost-effective and energy-efficient option for organizations looking to improve their data center efficiency. Now let’s come to the pricing part! For this let’s use the UAE power tariff with some relevant assumptions and considerations, as shown below.

For simplicity and easy comparison, the table below only selected two models from the above switching comparison table, which are almost similar in key specs [ Bandwith, throughput, etc].

OPEX- Power Calculation: Arista-7050SX3-48YC8

OPEX- Power Calculation: Cisco-Nexus 93180YC-FX3

Below are the key assumptions and Notes

Summary

Data centers are a major source of energy consumption. By investing in energy-efficient data center solutions, organizations can reduce their environmental impact and lower energy costs. Arista Network and Cisco Systems are both leading providers of data center solutions. Based on the calculation Cisco Switches’ power consumption price/utilization is 162% higher than Arista Network Switches. However please note that the power consumption of the switches varies based on its traffic load, performance capabilities, etc. Hence, you may see a difference in results if you test this in real time. We advise validating and reviewing the numbers and capability before buying. For more information and reading on the related solutions please refer to the Datacenter Networking Section.
