Gartner warns about virtualization & blade hype
Blades have nothing to do with virtualization. By chance both technologies can be used to achieve server consolidation. But beside that, at least at today, they are not enhancing each other in any other way.
And I'm glad Gartner seems to think in the same way, as SearchServerVirtualization is reporting:
Gartner's research vice president John Enck is tired of the hype around blades and headlines about blades and server virtualization being the perfect marriage in particular.
"It isn't a marriage I want to be engaged in," Enck told attendees at his session, titled "Blades and Virtualization: Choose One, Both or Neither," held at the Gartner IT Infrastructure, Operations and Management Summit in Orlando last week...

I could not agree more. I get phone calls on a weekly basis from some kind of HP or IBM reseller telling me that I would be much more better off with blades as opposed to my 4U 'monster' servers. Then they go on about higher density and reduced power consumption and save the planet. The reality is that density is 100% not an issue anymore in UK data centres but rather the 16amp limitation per rack which typically limits the number of servers you can have per rack to 5-6 ... the discerning reader just found out that by racking only 5, half of the rack is empty! Why do I need blades? Ohhhh, they use less power. We did detailed measurements with various loads and could not find a significant power saving between the two. The only thing I accept is that cabling will be a bit simpler, as long as the chassis provide enough connectivity per blade, something that is not the case for all models. My two cents.
