Yeah, that is what Hyperconvergence (in the modern) sense means, so there is no single node where something may be running at.
I've never seen that in any definition. That's the definition of HA, not HC.
A hyperconverged solution usually has more than a single node, and while it doesn't require it. If someone is looking to buy a hyperconverged system, they are looking for a node-n setup.
Not a single server, at my last job it was totally a hyperconverged setup, but without the HA aspect. SA was what it was setup for.
2 Servers, 1 running production, the other sitting there as a hot standby receiving CR jobs every 15 minutes.
All components contained individually in each server, but each server able to operate the business needs at a moments notice.
What you're describing here is a failover type setup in my mind.

I was of that a hyperconverged setup blurs the line between one node or several (like @scale does)...
But... what changes between one node and two or three? If the tech is the same, what makes one hyperconverged and one not? What isn't hyperconverged about a single node?
With a single node, you are limited to a single node.
I see hyperconvergence as taking multiple nodes and making them closer to behaving more like one node (again, like Scale does). Of course there are limits on each node, but the special sauce (yes, I'm stealing that term) ties the nodes together in such a way that some of these limits can be worked around.

Hyperconverged to me is bringing disparate interfaces and technologies into one box. Storage, Hypervisor, Management, and Network on a single box managed from a single interface.

But it's not. Using definitions like that, we are back to SAN being HC, which isn't the case.

That's what it has always been and the only thing that makes sense as a term.

Exactly. Which might be his point... end users use HC to mean HA. But HC itself isn't HA nor does it imply it.

Neither did my description of it

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)...

That's just boring virtualization. (Virtualizing networking, storage, and compute of a local server).
Hyperconverged infrastructure is an evolved term from converged infrastructure.
It was introduced to argue that CI systems were made of disparate vendor solutions and bringing it all together into a system where the hosts compute and disk bays took on the role of the storage controller in providing HA storage. The SAN component was rolled inside the server It was "moar" converged than a traditional CI stack.
Now some people are abusing this term. Netapp is describing a bundled deployment of SolidFire and SuperMicro servers is HCI.
Coheisity is arguing that they are hyperconvered secondary storage (because they converge secondary storage roles).
for a while Gartner said HCI had to be an appliance.
They are/where all wrong.

@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?

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.
