AFAIK Fujitsu still manufacture mainframes
- dralley 3y agoOxide could probably be considered a "modern mainframe" if you squint. The architecture is of course much different, but server CPUs from the likes of AMD are gradually catching up with the purpose-built stuff in raw power and I/O capabilities.
- zozbot234 3y agoOxide hardware is more comparable to a midrange computer. Though they are apparently planning to add support for having multiple physical racks in a single managed "silo", which enables HA scenarios and gets a bit closer to what mainframes provide.
- hindsightbias 3y agoThere's an article where their pitch was "It's the new AS/400" Or, you could just buy a new AS/400 that already does all that.
- msh 3y agoI think its only IBM people who calls computers midrange ;)
- steveklabnik 3y agoYes, like many kinds of comparisons, it really depends on what you mean by the thing. The architecture of Oxide is very different than a mainframe, but the "big computer that's a fully integrated system" vibe is kinda similar.
- timbit42 3y agoAlso HP NonStop (Tandem).
- osullivj 3y agoYes, I've worked on Fujitsu ICL clones running VME.
- pdw 3y agoThis is an interesting overview of mainframe vendors and how many customers they might have: https://arcanesciences.com/os2200/app1.html https://arcanesciences.com/os2200/app1.html Most of the "dwarves" are now using emulation...
- fomine3 3y agoFujitsu is planned to exit selling mainframe in 2030. NEC also still make mainframes and no plan to exit.
- lproven 3y agoIt does, but AFAIK, while it has 1 or 2 mainframe OSes still in maintenance, still getting updated, they run under emulation on x86-64 processors now. All the mainframe OSes I know of except IBM's run under software emulation nowadays.
