Many of us who pay attention to the Linux community recognize that moving from a proprietary hardware and OS (such as Solaris on SPARC hardware) to an open source OS (such as
SUSE Linux Enterprise Server) and commodity hardware can save a lot of IT budget. But the question is… how much will it save and how long before I recoup my migration costs?

Novell recently posted a
Solaris-to-Linux TCO Calculator which calculates the total cost of ownership over a 3 or 5 year period. It gives you nice charts like these and you can customize just about every parameter. Using mostly default selections, I threw in some basic figures (1000 users, 10 Sun servers, running a database), and the calculator showed a savings of well over $5M in direct costs over 5 years!
Check it out at the
Unix-to-Linux home page.
Plug in your numbers and post a comment letting us know how much you can save…
