Do you want Hyperconvergence?

But it makes no sense "for learning purposes". The Scale team has highly customized their system so it works as well as it does with the management tools they provide.
You're next best approach would be a shadow of what scale offers.

For 'learning purposes' doesn't have to make sense. Try and figure out a way to make it work -- because you want to. No, it won't look or work as well as Scale, but you will at least understand how the pieces fit together if nothing else.

But the pieces that would be missing is the entire management interface. So in this case, he'd purely be building his "own" solution.
Hyperconvergence is an easy need, and there are solutions for it, but not many with a full management stack baked into it.

Anyone can build a sort of hyperconverged "node" of multiple systems with the tools that are out there.
That is a great learning task if you want to know that skill.
But you cannot say you want to build a "Scale" system.
So if the OP wants to clarify that he simply wants to build some kind of hyperconverged system using KVM, then sure.

How can I build a 3 node cluster like scale on my own?
So what you have here is a lot of things (The Scale HC3) so we have to ask which parts you mean...
Scale HC3 has...
- Hyperconvergence
- A proprietary RAIN storage system.
- A custom orchestration management interface.
- Integrated support.
- Integrated hardware testing.
And more, but those are the highlights. Which of those things do you want? Without all of them, you don't really have a "Scale-like" device, but something else.
We understand you probably don't mean 4 & 5, but you likely mean 1, 2, & 3. And that's really hard, depending on how much flexibility you want to have.

I have a scale cluster already. I bought it I am just interested in doing to myself for learning purposes. '
Thats all.
Then it really comes down to defining your learning goals more closely. Once it is clear what you want to learn, then I'm sure a lab path will be easy to define.

I Understand now. so i wanted to build something that is like "SCALE" meaning the vm's with failover and I can spin up a vm fast. just to understand the technology.
I heard of KVM. Never played with it yet.

You can do this with any (pretty much any) hypervisor. Where the VM's will be running on one host 1 moment and a different one the next if a host goes offline.
Nothing here requires something as complex as what you're initial stated goal started out as.

KVM is the hypervisor behind Scale (and loads of others.)
So the things you want from your setup are a tiny function of what Scale does. All you are looking for is "high availability virtualization" which is a massively broad category. Scale does it in a very specific way, that is very good. But it's a cat and there are many ways to skin it. Some good, some bad, some just different.
