The maths must be contagious

So I'm still on holiday, but while getting myself prepared for the final stage of the re-decoration efforts at home I was browsing while having my morning intake of caffeine and came across an interesting viewpoint reported at Blocks and Files claiming that HDS are the #1 in storage virtualization...
I did a little digging and found the report on TheInfoPro (select storage on the right and it wants some details before it lets you view it). Now its difficult to actually see for real, but on the slide on page 3 it looks very much like IBM is ahead of HDS if you include in pilot projects. So have HDS been sharing their mathematical models with this research group too?!
A couple of things worth noting :
Anyway, statistics can tell you anything you want, and all vendors do it, but it would be nice to compare apples with apples, people who bought the USP primarily for its virtualization capabilities and not as a storage brick - however such data is subjective, difficult to obtain and probably not worth the effort. If you are one of those customers, be sure to contact your IBM sales rep when it comes to replacing your USP, you may find that SVC can solve the problems without resorting to days or weeks of downtime while you replace it.
Update: 21/4/08 : 10am I can't find the 10% reference, but I did track down a claim of only 50% of the USP out there have been sold with virtualization licenses. Case closed.
"IBM claims to have sold 10,000 of the SAN Volume Controller storage virtualization that it launched in 2003. Hitachi's virtualization software runs on the USP disk array that was launched in 2004, and the Japanese company claims that over half of the 6,000 USPs and diskless variants have shipped with a license for that virtualization software" CBR Online
Update: 24/4/08 : 1am A colleague found the link (thanks Chris), here HDS quote the 10 percent of virtualization use. Amended text in main body.
