Calculating your TCO for a Server Upgrade

Home » Blog » Calculating your TCO for a Server Upgrade

It is amazing what lives out there in the vast interconnected set of servers in the cloud known as the internet. We have all done the “use Google as my brain” exercise when someone casually asks “why does the data for Good Friday keep changing every year?” The answer by the way is the resurrection was thought to have occurred near the Jewish Passover, which was held on the first full moon following the vernal equinox. But this led to some churches celebrating Easter on the day of Passover while others celebrated the Sunday after. So the Council of Nicaea in 325CE established that Easter would be held on the first Sunday after the first full moon occurring on or after the vernal  equinox.

A similar Google search on “Cost of operating IT IBM i” brought up the IBM POWER8 Cost Savings Estimator at the link here:

In a previous blog, the Help Systems IBM i Marketplace Survey indicated a high percentage of shops (52.1%) still running on Power 6 and older servers, and of course this is a concern to IBM. How do you convince shops to spend money when everything is running well on the existing server? This may be the reason why the POWER8 Cost Savings Estimator is out there. The POWER8 Estimator shows you a 3-5 year cost comparison between POWER* and previous generations of Power server or commodity x86 server, including savings on hardware and software maintenance, facilities and labor costs.

You enter a basic comparison category (Compare to POWER* or Compare POWER8 to commodity x86 servers), and then on the next screen, enter some simple information from pull downs such as your primary operating system, the model you would like to compare to the POWER8 (i.e. your existing server), whether or not you are running multiple partitions and finally your primary workload. You can add up to 10 servers to handle your own particular environment.

Below is an environment with 1 Power 6 520 just running DB2 and a second with multiple partitions running JDE ERP:

Once all servers are added (you can use the red – icon to delete a server and add a different server) you click on Continue and you are prompted for the number of years of ownership to use for total cost of ownership (TCO), the type of POWER8 server being considered and your top 3 data centre concerns.  Click on Calculate TCO to get the results.

NOTE: In the results below a single Power520 running DB2 DB as opposed to our 2 server example so that the graphs actually showed more details.

We see a 62% lower TCO with significant savings in HW purchase and Application Software. If you click on the Register button on the same page it will show you detailed costs savings as below.
