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
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.

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.
isn't starwinds free for 2 nodes as well?
Starwinds is just free, period, if you don't need support.
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. -

R710 is old, but works just fine. The 7x0 series is excellent.

So what would the configuration be. Ovirt ran way to slow on these servers.
-
Are you getting new hardware? or saddled with the old stuff?
-
I was thinking of using the old stuff or get newer servers. not brand new. but Newer models.

Well, you're R710's are from 2009 - get something from 2016'ish will run circles around that old gear. Toss on the fact of SSD storage and 10 GB ethernet, you won't be able to pick yourself up off the floor.
Assuming Moore's law holds, 7 years newer equipment, you're looking at 6 to 8 times faster gear.
-
@Dashrender ok So what models am I looking for then?

We picked some some R720 / 720XDs, I think around 2015 / 2016.

Any place besides ebay to get servers.

@xByteSean one of ML advertisers... they are good ( So I hear) in spite of being an advertiser

Old stuff generally means high cost. You need many more servers to do the same workload. That means more power, more parts, more of your time to manage, and more complex setups.

Current model is 740, so any 720 or 730 would be newer / faster / etc. And definitely check out xbyte, they're on the ball with pricing and service.

Ok, I will take a look. What is the software or flavor of linux of choice. Centos, Ubuntu ?

Fedora if you want the latest KVM and Cockpit Web Console.
CentOS and Fedora is a lot easier and faster to setup a Headless Virtualization.With Fedora 31:
sudo dnf -y groupinstall "Headless Virtualization"With CentOS 8:
sudo dnf -y groupinstall "Virtualization Host"Or install it during the installation.

for me it is centos, cause of the logic :
If you want only one role to function in a server and it will not change, and you want it to do it good, and it does not require new features go with old stable or centos... everyone here will tell you fedora so you can be beta tester
