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.
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.

@Dashrender said in The Software RAID Inflection Point:
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.
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.

Who pays for MD development now?
The OS vendors, of course. It's part of the OS.

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.

Why would a company be willing to pay for support of RHEL, but not this?
Why would someone be willing to pay for XS support, but not support of MD in XS?

Then why not abandon it completely?
-
Here is the thing, I think you are scratching an itch that just isn't there. Who actually needs this functionality? Who is the real world use case where this script would change buying decisions? And how do those changed buying decisions turn into direct financial benefit for the company that makes and supports the new software?

Why do people pay for VMware with the same limitations (actually with fewer limitations?) Because you are picking something no one cares about and wondering why it doesn't drive decisions. It doesn't because no one cares.

Because there is no reason to spend money to abandon something that some people use and taking it out would make it super duper easy for someone to repackage XenServer with it and cut the XS team out of the equation.
Reverse the question, why WOULD they take it out?

Because one is important and the other doesn't matter. How much money are you willing to spend to get support for the sole purpose of avoiding buying a $700 hardware card that comes bundled with the server and is fully supported by the hardware vendor? In real dollars, how much will you convince your company to invest in software support for RAID to replace their current hardware spending on the same functionality?
-
aww, so that it. The price of a RAID controller is so low that getting a software solution isn't worth the effort. OK I think I'm on the same page now.
They can't do it cheaper, and still make money.. so why bother doing it at all. That makes sense.

Right, they don't care because it isn't much money and hardware RAID is universal (doesn't care which OS or hypervisor is used on top). If they need to pay extra for software RAID, the benefits diminish. And if you really need to save money, you can use MD RAID already today. Or you can get hardware RAID refurbished and it is not all that much, maybe $400. So the total amount of savings for customers is tiny, the effort is bigger, there is more risk and the potential profits to a vendor are super tiny, especially as RAID is basically dead already, and no direct way for any vendor to capitalize on it.
So no one is looking to pay for this solution, and no one is looking to make money by creating it. There is neither an itch to be scratched nor a scratch looking for an itch.

What does @scale use? RAIN?

Yes. Must like I describe with an additional layer that understands the drive speeds (like SSD, 10K and 7.2K.) So it does the things I mention plus it knows which bits go onto which type of storage.
