COMMON 2008 announced the POWER platform. Which is of course just brilliant. The IBM i is now just an OS, and to beat all that IBM released some new blades that are POWER based, so in fact you could run any of the the greatest OSes on the face of the earth on them, IBM i, AIX, or Linux, so why are they not selling. I think it’s just a matter of time and IBM doing what they don’t do best, marketing.
I have tried everything to get the company I work for to replace some older System i units with Power Blades but they have the same fears that is pointed out by this article by Mark Fontecchio.
I would urge anyone who has a need for 515 and 525(520) based server to really take a long hard look at blades. I think over time you will see the blades are actually cheaper.
