Dangit, you have a nice nerf gun to hit me with till I get those straight in my head?

Remember... Starwind is Network RAID and Scale is RAIN.

@dashrender I think I will setup a desktop and do some testing myself. I was originally curious if there was a consensus but I think it's pretty obvious there is not.
I think I will now setup raid on a desktop
To what end? If it's for testing purposes, I suppose that make sense, to give you experience, but practically, it's rarely worth it. RAID's purpose from my point of view is to survive some type of drive failure. But there are many failures your PC can suffer (mobo, power supply, RAM, etc). For most users, even CEO of fortune 100 companies don't have RAID on the workstations. (Scott will likely say that CEOs aren't the ones you'd see with this tech, and I agree, it's more likely that workers like CAD people, etc would be the ones with RAID in their workstation).
Most workers just need to make sure their data is backed up, then IT gives them another machine with their apps installed. -

- Is there much of a difference between Windows and Linux software raid?
Huge. One is enterprise ready and the other is so bad that it creates the need for the hardware RAID industry.
This statement no longer has any value, and hasn't for a long time now. It's based off of ancient data, yet you still say the same thing every time it's mentioned.
Don't confuse the lack of technical skill regarding a specific technology, with the tech itself being bad. I agree with your statement over 10 years ago, but this is no longer the case.
Personal experience of a tech in SMB does not reflect an entire industry or enterprise industry.
That said, I have used both almost equally in a number of scenarios, and in every case, I would say the opposite of you.
I think what it comes down to being "enterprise ready" is a proper GUI tool to manage it... but the tech itself, definitely enterprise ready.
A proper GUI makes something enterprise ready, really?
We've had GUI tools to manage LVM and drive partitions on Ubuntu/Red Hat/Etc for decades. Doesn't mean any sane person would run a GUI on one of those servers!
That's why nobody seems to use it... because lack of PS ability to manage the tech.
Ah, see there is the gap... it's used EVERYWHERE. It's super common. So that is the disconnect. It's insanely broadly used, without a GUI. Sure GUIs are available, but using one would be silly and non-enterprise. You are approaching this from a basic bit of misinformation - believing that some of the most common storage tools in teh world are not commonly used, and then making a logical mistep in trying to explain that misinformation connecting it to a lack of a GUI when there isn't even a lack, nor a need.
No, I'm trying to take guesses on why people can't manage it properly, screw it up, cant fix it, and blame it on the technology not being enterprise ready. My guess was that there isn't a GUI available and it has to be done via PowerShell, like most enterprise tools.
With Windows, GUI is bad and means you can't manage things correctly, because the GUO is always missing most features and management abilities... but not via PS.

OH, I think that I am following you now.

@dashrender Yeah it really is for testing purposes. I opened this topic because I wanted to get a better understanding of Raid than my limited experience had to offer and the various guides you can read explaining it. Every guide I have found does not go into any depth at all. I have learned Much more from this topic than from any previous article I have read.
At work I don't have any users who it would make sense to have a Raid system set up for currently. I just want to be prepared and know exactly what steps to consider if the use case ever does appear. While I am a noob compared to most of you all I still have no trouble setting up raid when I want to as I have a few times. I just wanted a better understanding of why and what other things to consider.
For myself there is value in me running a good Raid system at home. Who couldn't use a little better performance and reliability? I will do Raid 10. The most important thing to me is the learning experience and I like knowing best practices if at all possible. However, there are still things to consider. Remember everything I do at home is to help me learn something else in case I ever need it and I just like understanding things and am constantly trying to learn more. For home, what negatives do you see in using KVM so i can run lots of vm's in a Raid 10 system?
-
@tim_g That makes a lot of sense and just re-enforces the need to be powershell competent. I think your right about the rest too

None. It's all positives if comparing against the alternatives.

That's actually great for learning at home. Nothing is handed to you on a silver platter ready to go. That said, getting KVM and software RAID running is straight forward (notice I didn't say easy.)
