If you are familiar with Hyper-V and require Hyperconvergence, why not use Hyper-V and StarWind vSAN?
Absolutely free and scalable, support may be a bit more difficult but I'm sure the support costs are reasonable.
He might be familiar, but he's also been on KVM for the last three years. So that might be a factor.
He's been on Scale for the past 3 years, with support. Using it is vastly different than maintaining it when you have 100% support to 0% support because of finances.
If the goal is to use commodity hardware (which he has) and require a HC solution that costs nothing additional (besides setup and maintenance time) StarWind vSAN seems to be the option.
He could of course use XenServer and HALizard as well if he wanted.

So assuming all that is correct, and there are moderately okay servers to work with (710 are pretty old, that's our retired lab stuff here, too old to really bother running typically.)
There are three key options, all are pretty equal in overall production readiness. The differences are in a few small features, how support is obtained, how much support costs, and how much you like the interfaces.
- KVM with Gluster, CEPH, StarWind, etc. (You are calling this oVirt, but oVirt isn't the important part of the stack.)
- XCP-NG this has its own clustered shared storage, you don't use a third party.
- Hyper-V with StarWind
That's it. That's the list. ESXi is off the table, you don't have the funds for it. Leaves those three. You CAN use other options, like KVM with DRBD, but it's not practical or easy. These are the three reasonable choices.

Either that, or pay for your support renewal and plan the exit in 5 years when the contracts term.
This is almost certainly the right choice. It is in place, it is supported, and it gives you years of guaranteed functionality to get yourself to cloud where you need to be.
Anything you build yourself you are going to be on the hook for hardware replacements as you go and it is still just a hold out till you can cancel the services you have and get to cloud. But you'll have to keep investing in new hardware to keep it working once you are dependent on it. The drives in those old R510s are likely to die pretty often once they go back into use, that could get quite costly, quite quickly. Especially if they are SAS.

Just reading this thread top-to-bottom and wondered if anyone would mention that. OP is running 10 year old servers so the risk of downtime due to component failure has become exponentially greater.
I'm not certain if I'd be more comfortable having an HA setup between 3 very old servers or no HA on a new server (with warranty) myself... -

Totally agree. But one costs money and the other he has, so I get that. But it's not going to be super reliable. Three really old machines, all past standard retirement, without warranty or support, but with HA on top. It's not horrible, but it isn't great. But the failure rate on components could make it rather costly to maintain. Plus the higher cost of power consumption doesn't help.
-
If the three R710 servers are identical then use StarWind VSAN for the HA/VM setup and iSCSI Target the D2D4324-G2?
-
@PhlipElder : Not intimately familiar with SW's vSAN only having tried it a few times years ago, but I assume you're suggesting using the servers for compute and HP for storage? Doesn't that completely eliminate HA as you now have a single point of failure that will affect 3 servers?
-
@manxam vSAN is a hyper-converged setup with local storage being used on each node to provide HA storage for the compute.
The iSCSI Target on the standalone unit could be for backups, archival storage, or any other storage requirement that comes to mind.
-
@PhlipElder : Thanks for the clarification!
-
@PhlipElder will look into that as well.

Absolutely no one here has or will suggest anything that involved external high risk storage. All of us are trying to get you to some form of hyperconvergence which by definition means that the storage is local and shared.

Meh, I don’t see the issue. Those are just standard Dell servers, oldie in truth. Sell it in bundle and buy a new R740 with mission critical support. You can get a very convenient quote that include VMware and Veeam. The latest Veeam (9.5u4) can do native S3 (and S3-like) archive tiering and support direct restore to both Azure and AWS.
If we’re talking about steady-state workloads, on-premise or colo is always cheaper than IaaS. Oh, don’t forget that with the new iDrac/iLO you can treat the server effectively as a colo machine with all the good stuff like remote KVM, proactive support, remote automated installation etc., all with good html5 interface. Yes, that crappy activex/java is gone. -
@Francesco-Provino the issue he needs something today, and that won't cost him anything today.
It is a good option for sure but I don't believe he is wanting to spend money. But if he was going to look at purchasing something with warranty, look at xbyte.com

So are far as warranty, I get it. I need that. However the cost of new equipment at the present time is out of my budget. I would love to sell my scale server, But I have to have something else built. Scale for me is designed for small business, Not hosting companies.

Why do you have one then?
-
I was working with a guy at my previous temp job and he recommended them highly.
-
@mroth911 you've yet to state why you need all of this uptime, besides from the sunk cost issues that have been discussed.
It would be cheaper for you to just turn off the power on these systems and host them on a service like Vultr and literally sell all of your equipment.

@DustinB3403 I can not do that!. I have two 5 year terms with fiber. It would lost me like 80k per ISP to cancel.
