In December 2011, I wrote a post highlighting a valuable tool for Avaya stakeholders interested in various solutions, titled Check out the Avaya Product Calculator Toolkit. Today, I am pleased to revisit that tool, which has added important functionality from Avaya Networking. In this post, I want to walk through how this new functionality works as well as point users to the testing that underpins the results.
Calculator Homepage
On the homepage of the Avaya Solutions Calculator, there is a new radio button titled Networking. Interested in giving it a whirl? Just click through and selected the number of employees in your organization and select Continue.
Ethernet Comparison Savings
Now, select your existing switch vendor and model, as well as the quantity of switches currently deployed for your solution.

Results
This yields comparisons between your existing deployment and the savings potential. Outputs include yearly maintenance and energy costs, as well as TCO (Total Cost of Ownership) results. Should be straightforward enough and I highly encourage you to give it a try for your organization.
The Math behind the Calculations
Of course, a product calculator is only as good as the data that underlines its assumptions and methodology. In this case, Avaya has "engaged Miercom to evaluate the plug and play features and ease of configuration of the ERS 4548GT- PWR Edge Switch. The energy efficiency of the ERS was compared to similar switches and is discussed in this report as well." It is important to get verified, repeatable and documented analysis, and we are proud to have worked with Miercom to ensure a fair and accurate test.
Miercom testing methodology
To determine the power efficiency of the Avaya ERS 4548GT-PWR and how it compared to similar switches, the power consumed was analyzed at various load levels and with a variety of frame sizes. Testing was performed at frame sizes of 64, 512 and 1518 bytes at rates of 70% and 100% line speed.

Comments
Great work - really nicely executed tool. TCO matters!
