Discovering FakeRAID in the Real World
-
The drivers you mention needing to install pre-installation (which are now included in most OS's) would be supplemental packs that you would install.

Something that used to catch people offguard with FakeRAID...
They'd start with a Windows system or something that had the RAID software on it. They'd use their box for a while. Then one day they'd install a different OS, one that doesn't include the driver, and suddenly their Windows data, and their RAID, is all gone. Just... poof.
Hardware RAID, even if coming from a motherboard, would still have the data there because it doesn't depend on the OS for the RAID. Download something like Dragonfly that doesn't include FakeRAID drivers and file up a LiveCD or whatever. The RAID won't be there, proving the motherboard, or any hardware, isn't providing it. The only thing removed is the OS that was doing it.

Right. Used to be required all the time. Now they are rarely needed. Nearly all FakeRAID vendors, especially the big mobos and Intel, have moved to standard, signed drivers that Microsoft bakes in for them. It's tiny code, so not a big deal in the grand scheme of the OS storage. Fedora, Ubuntu, all do the same thing.
-
Not long ago, almost no Linux included FakeRAID drivers. But as Linux use on consumer equipment got more popular, people wanted it for whatever reason. So they started including them. I think this was likely sponsored by the FakeRAID vendors because they wanted to make it less casual to accidentally prove that the system had no RAID on it like they'd been led to believe when they paid extra for the motherboard.

And what lets you do this by default out of the box. What's the enabler? Is it the power supply you are configuring? No, it's the motherboard. This is all about the motherboard doing this. This is what I mean by coming with RAID. THe means, the how, fakeraid/software/hardware whatever... makgin a config somewhere for software raid and drivers to pick up later after the OS is loaded, all irrelevant for my original point and the point i've been makign this whole time.

The OS, as I delved into above.

Beaten to death. The motherboard is not doing this. Why would you think that it is? How do you think that that is even possible?
The motherboard, of all things, is not the enabler of FakeRAID. It's the mobo manufacturer in this example making it fake, but it's not the motherboard providing any functionality.

Exactly, I understand that. And like I said, it's that the motherboard ISN'T doing this, is why I say it does NOT come with RAID.
Read my example of how it works. The RAID is, and always was, in the OS. It's provided by the OS installer, it doesn't exist without the OS installer. But it CAN exist without the motherboard.

We've covered this too. You can't state that your point is that it is hardware, then claim that it being hardware doesnt' matter. You can't have it both ways. The discussion is that we had said it was FakeRAID (not FROM the mobo), and you claimed it was hardware RAID (FROM the mobo.) That's the whole point. Anytime you say that this doesn't matter, conflicts with what you say the point is.
Bottom line, motherboard does not create, maintain, provide, or power the RAID. The RAID isn't part of the motherboard. The RAID exists with or without the motherboard. The RAID comes from the OS and / or third party drivers installed onto the OS. That installer is not from the motherboard.

If you got a motherboard that didn't "come with RAID", you'd have to either install hardware, software, or both to make a RAID. Regardless if the OS you use has the drivers/software built in, it won't do anything, because the motherboard doesn't have it in there to configure.
Now, if you buy a motherboard that does have RAID built-in, then you don't have to do anything other than have or install a regular OS.
In the case the motherboard didn't come with RAID built-in, well, then as i said above, you need add a RAID card, or do extra stuff to create a software RAID, like configure Windows software RAID. But when the motherboard has it built-in, you don't have to do anything.

Right, and I covered this ad nauseum. You DO have to install it to make a RAID and you do, every time. Are you telling me you didn't install an OS? If you installed an OS, then you installed the RAID software.

Incorrect, most of us do this all the time. Normal RAID has no such limitations. @WrCombs just did this in the other thread, in fact, while we were having this discussion.

In both cases you have to configure it and install the OS containing the software. The motherboard doesn't simplify the process. At best, you are arguing that you like one particular software RAID's menu better than another's. That's not really relevant.
In both cases you have to configure the RAID, and install the software. They are, quite identical. Except one tries to trick you into thinking your hardware is doing part of the work, and the other is honest. That's about it.

You took this out of context.
However, when in context, you'll agree that simply installing an OS does not give you RAID. That was the point there. You'd need to set up a RAID first, whether via hardware raid, software, or whatever. Don't take thigns out of context like that.

Many enterprise software RAID systems also do RAID without any work, out of the box. In fact, one could argue that most FakeRAID takes MORE work, and provides less than many normal software RAID systems.
Windows software RAID is clunky and confusing, and handled late in the process. That's unfortunate. But you can't use that one bad software RAID example to determine "how software RAID works." Take a Synology box, that will do RAID with far less configuration than any FakeRAID system I've seen.
FakeRAID could do a totally transparent install, too, if it wanted. Any software RAID could. It's not that one is easier than the other, it's that both are just the same thing. Both are software RAID. Neither has an advantage at the code level.
It's just the one is promoted unethically as a scam, and the other is up front and honest.

I had already written something up that disagreed with this.
In both cases, you have to set up the RAID equally. The motherboard doesn't make things easier here.
Both cases you configure, both cases you install. In both cases, the installation is typically done as part of the OS install and totally transparent. Both optionally require manual acquisition and installation.
But some software RAID, like common in a NAS, does not require that and does it all automatically. So even the configuration piece is not always required. That's simply a choice of the implementer.

Yes it does.
When the motherboard DOES come with RAID:
- Configure RAID in BIOS
- Install OS
That it's fakeRAID is irrelevant here. I'm just saying RAID.
When your motherboard does NOT come with raid:
- Install separate RAID hardware
- Configure RAID
- Install OS
or
- Install OS
- Configure software RAID in OS
-
@obsolesce What you are missing (it's easy to miss) is in the first scenario you are setting the options on a config file (at best) and the OS installation process is smart enough to see that the configuration file is "setup" and applies those settings while installing.
-
@obsolesce said in Discovering FakeRAID in the Real World:
Yes it does.
When the motherboard DOES come with RAID:
- Configure RAID in BIOS
- Install OS
or...
) Install OS
When your motherboard does NOT come with raid:
- Install separate RAID hardware
- Configure RAID
- Install OS
or
- Install OS
- Configure software RAID in OS
or...
- Install OS
In both cases you are making incorrect assumptions about what is needed. Both can be as simple or as hard as they want. In neither case is it the FakeRAID making the difference.
And, FYI, enterprise Software RAID can do all that BIOS menu stuff, too. That's not what makes it FakeRAID. So everything you are describing as an advantage, is equal. Silly, most people don't want that, but definitely an option to do.

Right, instead of doing the setup in reverse... starting the install then configuring. But if you need to configure it, it's the same two steps either way. Same effort.
