The last blade server for BladeCenter chassis is the HS23, but I think these one will be hard to find too... since there is a new chassis for IBM that is PureFlex System and that was sold to Lenovo... but based on trust you have in IBM I recommend you take a look a IBM Flex System x240 node or if you need a bigger node, check out the IBM Flex System x280 X6.---

I purposely avoided moving to flex. I have 10 chassis of the HS, my only goal is to extend the life of these as long as possible so that some of the dust settles and when I move into the next phase of compute, it's the right step. Right now, I'm leaning towards complete SDDC (read evo), so the expensive arrays go out the window. I see the "pod" as not only rapidly growing, but achieving dominance. If I can get a couple more years out of these chassis, I see no reason I can't start into the more modular design.
