IBM's mainframe-blade hybrid to do Windows

The point of this?

I'm not wholly sure I see the point of all this (at least from a customer's point of view). There seems to be precious little real commonality of technology between the mainframe side and Xeon blades. I hope this thing is properly modular so that swapping out your mainframe to a later generation doesn't mean you have to change all the Xeon blades too (or, more likely, vice-versa).

The clue on the this would appear to be the wording of a "land grab" by the mainframe execs. That rather gives an impression of IT department warlords at battle with one another, with this as another weapon. Not a great way to run any company.

I rather suspect that, in the x86/x64 space, IT managers are better off picking the best and most cost-effective solution for their purposes (which might well be a single-source supplier), but it's not obvious what a mainframe integration will do for most customers, even the mainframe ones unless that's almost all that they do.

IPv6

It's a pain to configure as well, IPv6 is mandatory when setting the IEMN link and based on the *ahem* wonderful atempt at installing our first z196, it would be nice if the engineers had documentation that was correct.
