Maybe Hyper-V is more well known by more sys admins world wide and that's why it's so widely used?
Absolutely, marketing, not tech or business utility, drives 99% of IT decisions. As @StorageNinja once said, 99% of Hyper-V installations are done by accident or by mistake. People think it's supported when they install it, or they think it is requires for Windows or they think it gives them special licensing. Hyper-V is an okay product, but ask people who have been deploying it for any length of time, and nearly all of them will give you a reason that they chose it that is false, and almost always it's the same tired licensing mistake that tells us they don't know literally the first thing that everyone learns about Hyper-V.
Ask: What's the first thing to know about Hyper-V.
And everyone knows that it is "It's free and has no license and gives no licensing benefits."
Yet 90% of people using Hyper-V openly state that they use it because they "go the license as part of a package" or that they "need it because of Windows licensing", both of which contradict the very first thing you talk about with Hyper-V! It means the average deployment has never had even the most casual conversation about or investigation. It was not understood and someone deployed it thinking that it was something that it wasn't, and they kept it either because they never figured it out, it was too late, or whatever.

Everyone knows Windows Server, it's a natural and free progression from there.
In the world of IT doing things based on "what they heard of" and not "doing their due diligence", absolutely. There is no surprise at all that it is everywhere in bad installations.
Not that good installations don't do it, it's just that they are not the norm.

John White and I used to keep a list of people who were mistaken that Hyper-V had special licensing rights. At one point it was over 75% of why people went Hyper-V.

And, this is huge, that's 75% that had to have admitted it.... which is astounding given that it must have been almost always in a venue where people were constantly pointing out how silly that myth was. So anyone admitting it had to be very willing to look quite foolish. It's nuts that 75% even fessed up to that mistake under the conditions! The actual number has to be way higher.

Everyone knows Windows Server, it's a natural and free progression from there.People who's entry into the field is Microsoft certification training this may be true, but I find it's just enough to deploy and troubleshoot a non-clustered instance. Once you mix in clustering their ability to deal with CSV's generally isn't there.
Some small cluster deployments are because Microsoft paid (quite a lot of money actually) to the partners to stand up a Hyper-V Cluster. Throwing money at the channel will get a product deployed until it burns someone.

I think that he means that the name is more well known. I think it's very obvious that the product itself is not well known at all, and especially not known or understood by Windows admins. They are specifically the group that seems to have consistently no base level knowledge of it, it's relationship to Windows, and constantly repeat the "everyone has been told" myths over and over.
If you talk to other IT disciplines, knowledge of Hyper-V seems "normal". But specifically in the Windows Admin ranks, the pervasive misinformation appears to have taken such a firm root that the group you'd expect to have the best passing knowledge of it seems ot have the least.

This is what explains the numbers around things like S2D, too. Channel pushing it where it makes no sense and the customers are too small so that when it fails, no one hears about it.

What do you mean by this... that those people thought Hyper-V gave them special licensing rights to running Windows guests or something?

Correct. People who deployed Hyper-V because they believed it provided something that was not true.

Cosmos Darwin: Storage Spaces Direct: 10,000 Clusters and counting
I'm curious to see how much permanent data loss has occurred as a result of using S2D.
Very little, because no one is using it in production. This helps them hide just how bad the situation is. Only 10K clusters means it's not even being tested heavily.
"No one is using it in production." <-- False.
Making broad brush stroke claims like that is fallacious at best.
There are in-production S2D clusters.

The point being, extremely few. To the point of being statistical noise.

figure cited is the number of currently active clusters reporting anonymized census-level telemetry, excluding internal Microsoft deployments and those that are obviously not production, such as clusters that exist for less than 7 days (e.g. demo environments) or single-node Azure Stack Development Kits. Clusters which cannot or do not report telemetry are also not included.
When you have 10K clusters, and your competitors have (Singular) customers closing in on that many clusters that's noise. VMware is reporting over 14K Customers.
The industry standard for reporting product usage is reporting total customer count. Microsoft either knows is embarrassing low, or outright doesn't have the information. My lab which includes a SSD cluster (which is nested on top of vSAN) qualifies as "production" by this definition. Hell if Starwind or Veeams QA lab is leaving stuff on over 7 days he's a production customer!
For comparison VMware and Nutanix both state the number of paying customers they have on earnings calls. This is audited, and making a false statement here could incur jail time. Since both sell discrete software SKU's for their HCI product (and can track generation of licensing keys in the portal) they can give real and actually specific numbers. VMware's phone home tracking (CEIP) can at least tell if a licensing key is a production key vs. a demo or lab license key. It also can tell if the deployment is nested (is the hardware detected as "VMware or some sort of paravirtual device) making it easy to filter and identify. Microsoft including all clusters more than 7 days old that were not on their network and include non-licensed clusters is highly dubious.
When a vendor uses odd qualifications to report customer adoption that are non-standard and use vague criteria you assume the reality doesn't smell like roses.

As far as licensing S2D goes, we SPLA the DC license with our SMB deployments starting at 10-15 seats and up. They are also great ReFS repositories for Veeam (something they request to have under their backups).
This only works if they are on your servers, running in your datacenter. You can't use SPLA for customer owned gear.

Last I checked, you can use SPLA on customer gear. Rule was changed about 1-2 years ago, IIRC.

My opinion is Hyper-V is only an option when you need vSAN, otherwise I’m just not buying it.
What makes it special in that case? AFAIK there is no production vSAN for Hyper-V that is unique to it. Hyper-V is effectively completely dependent on Starwind for vSAN and they recommend KVM most of the time.
Right, Starwind makes it a more viable solution because it’s free and easy and well documented, right?
No, Starwind does not. Starwind just doesn't discriminate against it. Starwind is just as easy on VMware or KVM. So it's a draw, unless you consider Xen, then it is just a negative for Xen.
Eh not really. They dropped support for the virtual appliance on anything other than VMware. So you have to manually do the work on KVM/Hyper-V or just aren't able to do it at all. I can't tell.
This one will be back soon. We'll have a GA for VMware VSA around next week and KVM will follow.
In general we shift our focus from "Hyper-V and VMware" to "VMware and KVM". Reason: Hyper-V doesn't grow anymore and KVM has very high chances to supersede it. VMware... There's just more money there

@kooler
Hello everyone!
Let me add some insides about StarWind VSA since I am with StarWind for some time:)
As it was mentioned already by @kooler right now our development team works on the next release of StarWind VSA. The main focus at the moment is VMware and KVM - thus we will get HyperConverged setup with KVM and StarWind!
Stay tuned! -

Could you expand on your statement about Hyper-V not growing? Thanks

% between VMware, ESXi and KVM for acquired number of customers doesn't look good for Microsoft.

That is interesting. Do you think (or anyone here) that it is because of Microsoft focusing and moving more clients on Azure?
