Is HyperConvergence Even a Thing
-
@John-Nicholson then there has to be a set of descriptive terms for the items you're describing.
Multiple SAN's tied together to act as a HA SAN doesn't make it Hyperconverged. Because the system as designed is only working at the storage layer/network layers. There would be no hypervisor or processing power there.

@John-Nicholson This makes me wonder what D&D alignment @scottalanmiller would be. Chaotic good?
-
HC eh... What does HC multi box look like if not HA'ed?
For example, I'm not sure I consider MS's hyper-v manger a HC interface even though I'm sure you can put many hyper-v hosts into it so you have a 'single pane of glass.'
If you have 3 Hyper-v or ESXi or whatever all with their own storage, yet managed by a single console are you really HC?

I see hyperconvergence as taking multiple nodes and making them closer to behaving more like one node (again, like Scale does).
But it's not. Using definitions like that, we are back to SAN being HC, which isn't the case.
But SAN is not like Scale. It only does storage. The Hyperconverged idea brings everything (virtualization, storage, networking, etc) under a single console...whether one node or 10. (Ha! I managed to not say single pane of glass, lol)...
No, but SAN meets the definition given. That's the thing, we have to be careful with the definition or we are just overlapping with other terms.

I worked at a place that used those terms. It's one of the reasons I couldn't work there. I'm very chaotic good, while my boss was lawful evil. The degree of fundamental opposition was astounding. What's interesting, though, is in a world of strict rules, which that job was, being chaotic good allowed me to play the rules, hard. I was able to control a lot of things because I knew and understood the rules, even if I didn't believe in them.

It looks like Scale does if you don't use HA

If some marketer decided hyperconvergence is a thing, then it is obviously a thing. All hail the marketing department!!!! Believe all their dicta!!!!! Why would vendors, marketers, or sales d*cks want to lead us astray? Certainly not for profit.....

Not sure what you are describing. Do you mean that they are not a cluster, just managed together? Or are they a single cluster?
For example, a non-HA Scale cluster maintains all features of HC, just not HA.

How does SAN meet the definition of hyperconverged? It provides only storage. Hyperconverged supposedly brings storage, networking, and virtualization all under one roof. In HCI, you don't use separate SAN software to manage the storage, and separate networking software to manage the network, and separate virtualization software to manage the virtualization.
You have one interface to manage the complete infrastructure. Again, like Scale Computing. You keep going back to SAN, but SAN is nothing like what Scale computing is doing with everything (again:storage AND virtualization AND networking) in one platform.

Go back and read the definition that I responded to. It left out bits like having all of the pieces.

I keep going back to prove the point that the definitions being given have to be wrong.

I must be blind, lol. I'm not seeing which definition you responded to. Which post is it?

This one that I quoted: "I see hyperconvergence as taking multiple nodes and making them closer to behaving more like one node".
Clustered SANs do exactly this. They take multiple nodes and make then behave like one node. But they lack the convergence piece. That's why that definition is bad, it leaves out the parts that matter and focus on the part that isn't actually part of hyperconvergence.
Convergence is about collapsing the vertical stack, not about scaling it horizontally. By collapsing, we get to scale horizontally more easily, but even at a scale of one, we are still hyperconverged. Just like how RAID 0 is still RAID 0 with just one drive.

Okay, let's clearly define the term hyperconvergence.
-
Hyperconvergence is merging of the platform components into a single node: with hypervisor, storage, networking and generally management.

Hyperconverged is a software and management concept in my head. It really has nothing to do with the underlying hardware or infrastructure.

Not sure what you are describing. Do you mean that they are not a cluster, just managed together? Or are they a single cluster?
For example, a non-HA Scale cluster maintains all features of HC, just not HA.
What is the point of non HA cluster? You're still managing each hosts load individually just through a single pane. Is the really HC then? I'd say no... Because to be HC all things have to looks like one giant thing, and the where and how it's running really don't matter.. i.e. normal Scale setup.
But if your remove the system self managing what work load is where, what vhds are where, then you are back to managing many things. With the exception of a single box, well because as already stated, a single box is HC, and always has been.

What do you mean by "single system"? Single management platform?

I reworded as that was definitely weird.

Why do you think that? HA means high availability, it doesn't imply that the loads aren't clustered and managed as a single thing. Just look at Scale.
