What makes a system HCI?

Oh, missed the second part. By magic I mean the vendor talk where I keep hearing you just plug in another HCA unit to expand resources. You don't need to understand whats happening under the hood, you just need to drop some cash and plug the next node in to the HCA to grow. That is what I meant by magic.
That's automation of HCI. It's what makes it really, really nice. But it's not HCI itself.

Just had a look on the VXRail spec pages and that also allows for expanding network cards for capacity/failures. So that helps my argument at least.
Your argument to avoid VXRail?
If you are shopping for HCI your short list should be Scale, Starwind, and maybe Simplivity.
Your absolute never, ever, ever even talk to them or let anyone who sells them ever through your door is Nutanix.

I get that a vendor has some cool tech they stick on top of their HCI hardware to sell me a HCA, but you can still have HCI without that super cool layer on top that they have, right? Or are we saying HCI can only ever be HCI if it has all the bells on top that vendors sell through their proprietary software/stack?
You could do HCI yourself, sure but building the tools to get it aren't something any individual would reasonably do.
And loads of people do. I've been doing it in production for almost 20 years. We used to use things like DRBD for it.

Yeah - I thought this when others were saying the "tooling" was a requirement of HCI... uh.. nope, not a requirement.. but a definite nice/want to have.

What I am trying to get an insight in to is..... if the system does not do the above, does that mean the system is not HCI?
HCI does not, in any way, imply that it does what Scale HC3 can do. Scale HC3 is high end of HCI solutions. If everything that Scale did was required for things to be HCI, no one but Scale would be making HCI!

Would users of Starwind vSAN, running a three node setup using their vSAN with WFC on top be HCI? Three nodes, all shared storage, to a Windows Failover Cluster running over all three nodes... sure, its not as polished as the scale solutions (never said it is).... but does that mean it is not HCI?
Starwind is the leader in high performance HCI. Starwind leads performance and scaling. Scale leads ease of use and automation. The two together effectively define HCI capabilities on the market. Everyone else is an "also mentioned."
How can this be when right at the start somebody said HCI is:
Compute virtualization
Networking virtualization
Storage virtualizationBecause no aspect of that statement is true. Storage virtualization means nothing. NEtworking virtualization is very rare even in HCI. Compute virtualization is ubiquitous and you can't even call something production without it. None are a factor in defining HCI.

No, one does not mean that the other HCI solutions aren't HCI. It just means that the tooling isn't there / included.
Different HCI solutions can have different features.
Ok gotcha. Thats what I suspected. I do see the value of such solutions, but I am trying to understand why my teams are arguing one solution is HCI, and the other is not. Where the only real difference is this tooling.
HCI is all about the tooling. Without the full stack tooling, it cannot really be HCI. Just cobbled together pieces of hardware that might mimic HCI.
So HCI can only be obtained by purchasing a solution from vendors like Dell, Scale, Nutanix, VMWare?
Simply then, if the solution is not some proprietary tech from a company like that it will never be HCI, as it does not have the tooling?That's what vendors want to sell you. The vendors work hard to promote this "special sauce" vision of whatever products are out there. We went through the same crap with SANs if you remember. People were convinced that it was the bells and gimmicks, not the tech, that made something a SAN. But in reality, every USB hard drive is as much a SAN as an EMC Clariion.

Proxmox offers Hyperconvergence and HCI if you have multiple hosts in the same pool. This is free and open source (and clearly isn't propietary).
If you wanted to test it setup 3 servers and go to town.
Yup, ProxMox is an HCI offering. XCP-NG / XO is one. Straight Linux will do it. Ubuntu offers a couple options right in the OS. Windows offers one. Starwind offers components to build one on top of other things. ANd on and on.

Of course not, the linux community could (and likely are working on) an HCI solution right now.
HCI != ProprietaryIts about having the tooling, not the provider of the tooling.
Ok, I can take that on board. So... let me rephrase with that in mind...
Is this correct to say then: If the system does not have the tooling on top of the hardware it cannot be HCI.
Correct?
You don't need tooling to be HCI. You need tooling for HCI to have any particular value.

In what insane universe does a board...
- Talk about IT
- Know what HCI is.
- Have any ability to discuss this.
- Get into the weeds of understanding really, really technical IT underpinnings that no normal IT department knows?
-
@Jimmy9008 said in What makes a system HCI?:
"So on HCI I think most people agree that you need to have:
Compute virtualization
Networking virtualization
Storage virtualization"Yes, but, absolutely no one agrees with that. No HCI vendor, including Scale, VxRails, Starwind, or Nutanix, does those things.

I didn't notice this or maybe I just read past it. But @Jimmy9008 are you being asked to present to a "board" what HCI is?

@JaredBusch said in What makes a system HCI?:
@Jimmy9008 said in What makes a system HCI?:
So, which is it?
Both.
HCI does not require more than a single box. It is stupid, sure. But to quote, stupid is as stupid does.
Technically, a stand alone server meets the criteria of hyperconverged because it has all the things.
Technically a lot of things are factual from a very specific definition. Just poke @scottalanmiller on any number of subjects....
But no one can seriously consider anything, single box or a hundred, hyperconverged with out the tooling that manages it all as a cohesive thing.
Exactly. What "is" HCI is a factual thing that is very technical and while potentially interesting, is of zero value to IT to know and literally negative value for a board to know or discuss.
What IS HCI is one thing. What makes HCI valuable is a different thing. The tooling is the value, just being HCI alone isn't really a value.
That's why it is both. What makes HCI important and what makes something HCI aren't the same thing.
That your board needs THAT explained to them is what's of real concern.
THink about cars. WHat makes something a car and what makes a car valuable isn't the same thing. A car that costs too much, breaks down constantly, can't be fixed and is super dangerous has no value, but remains a car.

Nonono, not at all. I mean this in the sense of I can take the idea on board/understand what was said/incorporate it in to what I think... nothing to do with boards.

By "on board" did you mean - that you could accept that definition personally? or did you mean you would take to the Board of Directors at your company?

OH!! I was confused to. WHat kind of BOARD would want to know these things, LOL.
Okay, makes way more sense now.

So with this in mind, that architecture I wrote out above which is quoted is in fact HCI then? It may not have the bells that Scale has, but it is still HCI, right?

Yes, it's poormans HCI, because it lacks of lot of the tooling you (generally) would find great value in.

I think Scott misread that comment to mean something it didn't.. but time will tell.
