Setup 3 node cluster
-
@scottalanmiller Thank you very much for the mention.
Our Virtual SAN can support 3-way synchronous replication with Hyper-V, VMware or Xen. As mentioned prior, we will install on the hosts providing hyper-convergence and HA between the nodes. We do not require a switch for 3-nodes as we will recommend that they are directly connected to each other. It's a simple and cost effective way to accomplish the clustering that you are looking for. If you think that would be of interest you can always try a 30-day trial here: https://www.starwindsoftware.com/starwind-virtual-san
But if you have any questions please feel free to ask away!

Ok. I have 3 hp g7 same model. I want to set them all up as a cluster. same way scale does.
What Scale does is highly unique. What you have is a modified hypervisor that knows about the storage, a customer storage layer that is very advanced and designed specifically for this use and a then a customer web management layer that controls it all for you. That's not something you can build at home.
You can use VMware + VSAN (very expensive) or Hyper-V + StarWind (not cheap) to do this without some crazy complication. But I'm assuming that for an "old cluster" you aren't looking for an investment. If you were, you'd just buy more Scale gear.
So you are going to be looking at free. And probably Xen or KVM + CEPH is going to do that and that's not trivial, at all.
We'll try to fix that immediately after our V8 R5 release after NY giving away unrestricted StarWind vSAN for free. Switching to appliance business ;))
Wow, that's awesome!

Do tell!
Post here once that goes live.

That will do wonders for the Hyper-V market.

XOSAN would be a nice setup for 3 node cluster
Beta program in January! (not the final product but a test at scale to validate some choices).
It already doable "manually" but not trivial (but faaaaaaaaar trivial than using Ceph, for a 3 node installation, it doesn't make sense).
Ceph is like OpenStack (and they go well each other): they are good for large installations. Otherwise, it's a pain that isn't worth it.

You should talk to @KOOLER about his upcoming storage layer for Xen.

@scottalanmiller XenServer or Xen?

Is XEN Orchestra free?

English is a bit vague for the word "free".
It's Open Source. We sell a turnkey appliance + support + web updater. If you want to play with it from the sources, you can
-
How do you install it on xenserver
-
@matthewaroth35 The easiest way to start playing with it, is to download the virtual appliance. You just "import" it on your XenServer and you are up and running. Register on https://xen-orchestra.com
Then the doc is here: https://xen-orchestra.com/docs/xoa.html
-
I would have to do it to each server I have right ?
-
@matthewaroth35 Nope. XOA can be connect to any number of hosts at the same time. Just run it somewhere, it enough. See https://xen-orchestra.com/docs/architecture.html

Their layer is generic. Not specific to XenServer

You could build a 3 node HyperConverged Cluster using old servers with StarWind Virtual SAN as a storage provider and Free Hyper-V as the Hypervisor. In case you decide going that path, ping me offline and i will help you out with the configuration.
