    Er... windows 3.11 had the same minimum spec as Windows 3.1... 2Mb RAM. And a 15Mb hard disk. So the point still stands.

    And I have personally contributed to a project that brought Linux networking and TONS of extra features that we'd have died for in the 3.11 era to a single, bootable, 1.44Mb floppy disk.

    Sure, Windows 95 upped the ante, but in terms of what you were given was it really that much of an advance? That's where things started to go downhill if anything... networking stack, yes. Firewalling of any kind? No.

    And Windows 95: "To achieve optimal performance, Microsoft recommends an Intel 80486 or compatible microprocessor with at least 8 MB of RAM.".

    I think you're forgetting how much you could get done in 2Mb of RAM. Hell, Windows 95 can't even boot if you have 512Mb, it was never designed to have that much RAM EVER. I'm just not sure there was ever a feature worth quite that amount of system resources - at this moment in time, my Bluetooth tray icon takes more RAM than Windows 3.1 needed to load everything. I can't see the justification for that at all.

    CPU speed, yes, devices nowadays shove data through them a LOT faster than they ever used to so you need to be able to keep up. Disk space, possibly. But RAM usage? Why should a Bluetooth icon take more RAM than an entire former OS?

    The chances of the code even compiling any more are slim. Let alone the required hardware and devices being present in a PC.

    You're looking at a full emulation environment, which would kill all the performance anyway. It'd still fly on a modern PC, even so, but I can remember entire games fitting in 16Kb of RAM and Windows graphical interfaces that you needed to upgrade to 2Mb of RAM in order to run.

    Of course they'd be fast on modern architecture. But they won't run directly. And by the time you get them to run, you could have wrote a basic GUI that did the same in a language of your choice.

    The problem is not that we should be running ancient systems as they were back then. It's asking ourselves why Windows needs a Gig of RAM in order to even boot properly, when the user "experience" of such is a desktop background bitmap and a clicky button in the corner. Windows 3.1 could do that in 2Mb of RAM.

    Our DR plan is that we have an identical rack at another location with blades / storage / VM's / etc. on hot-standby

    Our DDR (double-disaster recovery!) plan is to restore the VM's we have to somewhere else, e.g. cloud provider, if something prevents us operating on that plan.

    The worries I have are that storage is integrated into the blade server (a SPOF on its own, but at least we have multiple blade servers mirroring that data), and that we are relying on a single network to join them.

    The DDR plan is literally there for "we can't get on site" scenarios, and involves spinning up copies of instances on an entirely separate network, including external numbering. It's not a big deal for us, we are merely a tiny school, but if even we're thinking of that and seeing those SPOF's, you'd think someone writing their article into Slashdot would see that too.

    All the hardware in the world is useless if that fibre going into the IT office breaks, or a "single" RAID card falls over (or the RAID even degrades, affecting performance). It seems pretty obvious. Two of everything, minimum. And thus two ways to get to everything, minimum.

Because they are made of cheap metal, they tend to be easier to forge than expensive security features like holograms, etc. The only "solution" is to follow what happened with the 2GBP coin, and that's to make it bi-metallic - which is the next plan from the Bank of England.
