Discovering FakeRAID in the Real World

@scottalanmiller said in Discovering FakeRAID in the Real World:
Dell and HPE both make some really silly software RAID devices that require hardware dongles and configure through the BIOS, but are NOT FakeRAID.
You talking about the S series, or the Intel CPU ROC functions for NVMe drives (which have a dongle for certain features, or the ability to use non-Intel drives). I thought the OEM's were shunning VROC.

The controller industry is crazy opaque.
This is really the only thing worth considering when looking for a controller. .

At home, I'll use LVM to build the RAID when using Linux, or the built-in RAID on my mobo with Windows. I don't want to spend extra money on enterprise RAID for at home. 99% of what I have at home is stateless, so reloads are easy. Worst case is I have to reinstall 70GB of games, but that's backed up so it's easy if I hit a scenario I cannot recover a RAIDed disk, or whatever.

@scottalanmiller What about RAID 1 on the motherboard? Yeah it's "fake", but it's still effectively mirroring the drives. I use that on my home pc and it hasn't failed me.

Thats what we use .

Depends on the implementation. Normally the question is not about whether it is better than nothing, but how is it better than the Windows OS' included RAID 1?

Is it? I thought you just determined that you didn't have FakeRAID, but had to use Windows RAID instead (which is the recommended choice anyway.)

That IS enterprise in the Linux case. Windows Software RAID is free, too, maybe not enterprise, but not horrible to the point of not being better than nothing.
Enterprise RAID is almost always free.

That's newer, and there is some interesting stuff there.
But I'm talking about the older SAS controller options (maybe it is S series?) that are basically just SAS controllers with drivers to install, but they are open about it and don't hide anything. Basically just a trivial step up from Windows Software RAID, but with support for Hyper-V, VMware ESXi, and most everything else, plus really simple management utilities.

@scottalanmiller there isn’t a software based raid option on ESXi unless you pass it to a VM or use vSAN. The cheapest raid controllers supported are the BOSS modules M.2 mirroring things.

I think that's what our VxRails are coming with.

I just know that we mirror Drives, WE use RAID 1 : Using
CLTR+Fduring the boot. Is it possible we are using FakeRAID? Completely! like we have all came to the conclusion of: This place is diseased with horrible practices. Why we dont use Windows RAID- but instead use FastTrak? I have no Idea. -

14Gen VxRAIL and ReadyNodes use's BOSS for the boot modules. VxRAIL keeps the factory re-install image I think on the SD Cards in case you need to factory nuke a node.

But the one in your other thread didn't support that. That's a unique one, though?

There used to be the S100 or something. I've seen VMware deployed (some time ago) with Software RAID from a third party.

Unique for sure, Because we us FakeRAID: but we could set it up to use Software RAID..

Right, you have options, but chose the weird one, it would seem. And the one that can't be used uniformly.

Sadly this falls under : Being Plagued by horrible practices . . .
