I've been reading a number of interesting commentaries on Cisco's launch of UCS and thought you might find them interesting. Having provided data for similar tools while at IDC, I'm convinced that these tools should be completely understood before their results are taken as gospel.

Dan Busby, VP of Engineering for eGenera, in a post titled,A closer look at Cisco pricing, pointed out that it appears that the Cisco's study was evaluating was an HP Bladesystem and that the cost calculator included some hype that would tend to confuse the uninformed.

When reviewing Cisco's TCO data, I can't help but be reminded of something attributed to Benjamin Disraeli, "There are three kinds of lies: lies, damned lies, and statistics." I'm sure he would have added benchmarks, ROI studies and TCO studies to the list had he known about them.
