I have played around with Ovirt, And Xcp-ng. I am going to try proxmox next. What are your thoughts on using local storage instead of a Shared storage.
All drives would be in sync with every node. with no san or shared storage.

Always. There is essentially no exception. Remote (often incorrectly called shared) storage has basically no place in production, never has. It's slower and riskier and more expensive. No upsides, all downsides.

Being in sync = shared storage.

That's called RLS or Replicated Local Storage.
-
Ok, So I don't want to use a san. I want to use the drives in the server's to sync.
-
@mroth911 here is my MangoCon talk on why RLS blows any external storage out of the water...

So, question is how to do set it up? LMAO

Depends on a lot of factors. So there are many players. Hyperconverged vendors like Scale, Simplivity, Nutanix, etc. have it all packaged into a single system so you just turn it on and that's that. It's all done for you.
All the other players give you the tools and you can make RLS or External storage however you like. That's DRBD, HAST, VMware VSAN, StarWind VSAN, Gluster, CEPH, etc.
XCP-NG has their own tools for this. StarWind is the leader for high performance systems. VMware VSAN is popular for people on VMware since it is all one vendor.

DRBD is quite popular for two node systems on Xen and KVM because it is free, baked in, mature, and screaming fast. Gluster and CEPH are popular for the same platforms where you want more scale, and less concern about performance.
-
Ok. I have an older scale system 1150., I want to upgrade the HDD but they told me to just upgrade the node for bigger storage.
I want to be able to 3 or mode nodes

isn't starwinds free for 2 nodes as well?

Starwinds is just free, period, if you don't need support.

Generally better to go vertical, not horizontal, due to storage complexities. Two giant nodes are way cheaper than four smaller nodes, for example. And way simpler to deal with the storage. Because mirrored network RAID is easy to have be blinding fast and dead simple.
You can do more than two nodes with any two node technology: DRBD, HAST, Starwind. You just have to either manually stagger the storage to make it into Network RAID 1e or have the vendor do it for you.

Oh - I didn't know more than 2 nodes was free - thanks.

Different ways to get it, but at least normally it has been free.

So which product is it? Is it this one?
https://www.starwindsoftware.com/starwind-virtual-san#VSAN-FREE
What kinds of servers do you recommend. I have dell R710. Or should I look for getting better servers? I am going to get all SSD drives.

Yes, that's the one.

Free version comes with an unrestricted set of features: multi-tiered server-side caching is
available out of the box, scale-up and scale-out are both allowed, VTL is not included.
