RAID Hardware sees.... drives destined for RAID arrays. MD sees everything on the system. They are very different from that one perspective alone.
OK, great, I get that - but nothing stops you from saying, this array is these device only, and when a fail happens do x.
So do it. Nothing is stopping someone from automating the process. It's just never sold to someone like that.
And the question is, why not?
Scott clearly loves software RAID - So why not make systems that automate this process based around limits you put in place? If something falls outside those limits, manual intervention will of course be required.
Because there is generally too much desire for flexibility and in large shops there is no need for this and small ones there is no market pressure.
No market pressure in small shops because they just go hardware RAID instead?
Yup, they aren't looking for a solution like that. And it would be rather complicated because you still can't visually inspect for it and know that it is always going to be the same and so forth.

No money in not selling solutions - huh? NTG for example could make money selling this solution. They get paid to set it up. Assuming the solution can blink the lights, then from that point forward, a bench tech can swap drives without concern.

Right, but you have a disconnect. The money to be made is from people unrelated to the ones that would spend the fortune to build the software to do it. And those that get paid to set it up that way already get paid to set it up the even longer way. So it's negative money to them.
Who do you foresee investing money into this that could ever recoup it?

- Get paid to set it up = negative income since they are now paid less to set it up AND they had to spend $100K making this solution and supporting it for forever.
- Letting "just anyone" swap drives lowest the dependence on an MSP, against, negative money.
I'm not saying that MSPs / ITSPs wouldn't use it if it existed. I'm saying that none are going to be making wise business decisions to invest heavily in obsoleting themselves. They could just "do the work for free" if that was their goal. And the biggest beneficiaries would be "every other MSP" who would get it for free.

I'm really lost again - MSPs / ITSPs are setting up hardware RAID today. This typically takes mere mins or less to configure, so setting up MD would take longer (probably) and give them more billable time.
The hardware RAID is already taking away the work from MSPs / ITSPs, so what's the difference there?

It doesn't work that way. It takes no time to set up either. MD RAID is already a "zero effort" set up process. But there is pay for supporting it. It's not that this would really hurt an MSP, but it would cost a fortune to make it and support the code, money that could never be recouped, not even with tens of thousands of customers all using it.

Takes me less time. But neither takes like over two minutes.

LOL, if you know what you want it to be, it should be a very fast process.

So each Linux distro has it's own version of MD? it's not universal like so many other components?
And they would never make any money ..... because they are already getting support contracts from those willing to pay, they likely wouldn't pick up additional ones, so this would be only a net negative? Is that what you're saying?

If you don't know, then the automated scripts won't work. It's one or the other.

It's a negative because there is no money to be made, just money to be lost. You would not gain customers from it, nor make more money from the customers that you have. But you'd have to invest a tonne making it in the first place and would need to test and support it for forever. There is no business case for it.
-
Try making the business case for it. State where the investment money would come from, how you will continue to pay for supporting it and how you will recoup the money.

You don't think that XenServer could get more customers by having this included? The customer wouldn't need a 1000$ hardware RAID card anymore.

XenServer doesn't even care to officially support MD RAID the normal way which is already there and works great. No, I don't think there is any way for XenServer, RHEL, ESXi or anyone else to make this make any financial sense whatsoever.
