"Plenty of RAS advantages"
Enough of the "plenty of RAS advantages" press-release-fodder. Kindly put up or shut up, preferably with justified examples, and with particular reference to AMD64/Opteron rather than Intel's 2nd-rate clones. I'm sure Matt will be delighted to help you on the Itanic front.
As far as I can tell, any substantial differences in RAS between an AMD64 enterprise-class Proliant, a mainframe, an Itanium, or whatever come largely from the OS software and associated management tools these days, and possibly from the kind of people working with them, and that isn't necessarily anything to do with The Chip Inside. E.g. a decent AMD64 Proliant with the NonStop OS on it (if such were to happen) would have pretty much the same RAS features and benefits as any other NonStop box, they'd hardly ever FAIL.
I'd be delighted to be corrected if someone out there has *evidence* (not just unsubstantiated quotes from press releases and snippets from off-the-record vendor briefings) to show otherwise, but I've been waiting for "evidence" for years and not seen anything worthwhile.
Have a nice long weekend. Thank you.
