New Infrastructure to Replace Scale Cluster

XCP-ng
I really want a product that works and can be put in productions. I have 24 cpanel servers that I cant have go offline.
You're still looking at this with brown colored glasses.
First you're wanting to setup something you've never used for production out of the gate. Granted there is a lot of documentation, but the same amount of documentation can make managing and setting this up difficult.
oVirt is powerful, but you have 3 hosts. Meaning if you lost power your systems go offline anyways. All 24 cPanel down.
Same thing would occur with any on-premise solution, power, internet, switching issue.
The idea that XCP-ng (or ESXi or Hyper-V or XenServer) aren't production ready are weird, when you have access to numerous choices for support. Only with ESXi is support more difficult to obtain freely.

This statement here leads me to think that you need to purchase support. Period. Or host these in the cloud.
On-premise is the "I can accept some downtime option".
-
@Dashrender No warranty on hardware. I am not big enough to get contracts etc.
I'm big enough to get contracts for home, how small is the business?
Warranty is something you get on a single server. Why so many servers, the scale you are installing doesn't match with your other limitations.

I'm assuming you require HA from a Scale type offering and that is why you are looking at oVirt. But I'm just confirming that you actually require this.
Since you said you're so small that you can't get support.
If so, that doesn't "jive" with his "no shared storage" requirement. SS is part of HA. No SS, no HA.

Exactly - how are you protecting these servers from an hour+ long power outage? Do you have multiple ISPs delivering you internet access? etc. HA requires so much more than just multiple servers with shared storage, etc.

I have multiple ips, 2 generators, on LP.

I get everyone view on this. However, I have a ton of equipment. I already have 5 year contracts with fiber. It would cost me more money to cancel the contracts 20K per ISP for me to put my stuff in the cloud. SO While I have all this equipment here that is collecting dust I can use it to make sure I stay up and running.

And that is fine, it's a cost of business for you at this point in time.
To offset that though, your business is setup so that downtime is unacceptable and is also acceptable at the same time.
Get the point where we are when we look at the topic?

You can setup a 200 node pool and have only the transfer time of your VMs.
Nothing would be shared and downtime would be completely minimal with very little to have to learn. Commodity hardware would work perfectly for this and you'd use tools and systems that have a wealth of community support available to you at no charge.

@mroth911 said in New Infrastructure to Replace Scale Cluster:
@DustinB3403 yes that is correct. I have a scale cluster already 1150. But its 3 years old. Harddrives are failing. And I cant manage it at all. It just runs and that's it.
Afraid if it craps out I am screwed.
More or less, yes. Purchasing any kind of appliance means a 100% dedication to maintaining support on it for the life of use, it's just part of the initial decision process. You should be able to manage it just fine, but replacing hardware that dies will be a major issue.

Thanks for fucking up another thread.
@scottalanmiller can you split this.
What the fuck are you on about. He has a scale solution today, and is needing to move to oVirt because he can't afford the support.
Hence the question, do you actually require HA?
It's not that it's a bad question, it's just different than "How to Manage oVirt". It's good to be asked, just better to be asked in a new thread is all.

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.

Why can't you manage the Scale cluster? The demos I've seen seem to make it super simple. Didn't seem that hard to manage.
If it's failing drives - buy the drives direct from the manufacturer, done.
I'm not sure that you can do that. Buy drives from the manufacturer, that is. Scale hardware is not generic and you can't just slap anything in there.

Exactly my thought, and my question relates directly to the obvious answer. Scale uses hardware raid. So replacing the drives should be the easy part.
Scale does not use hardware RAID. In fact, it uses neither hardware nor RAID. It is software RAIN.
But replacing drives is super simple. Acquiring properly firmwared drives might not be.

@mroth911 said in New Infrastructure to Replace Scale Cluster:
I would build it and know the bones and how it function. Beside the hardware I will know how. to fix things if it breaks.m
It would function the same as the Scale, just with some different shared storage solution instead of SCRIBE. The hardware will be essentially identical, Scale was just standard Dell servers at the time.
Basically you'd be building another, similar era cluster using the same components as the Scale you have now, but with needing loads of special knowledge, but with way easier ability to replace parts.

@JaredBusch Its all me with my company.
What's their plan if you are sick, hit by a bus, get a better offer elsewhere, etc.?
With the Scale, they pick up the phone and get 100% support instantly. With a built it yourself solution sure, they could call some of us, and hey, we'd love that. But it's not quite the same as having primary vendor support for the entire stack instantly.

I'm assuming this is a 1 man band.

So to ask a few questions.what about the scale system are you unable to support?
So here was a situation that I had, A hard drive failed and the system wouldn't recognize the new harddrive I put in. So I had to call them to do something in the backend to active port 2 to reanalyze and make the drive active
Yeah, this is where I think you get stuck. Third party hardware is unlikely to work in the Scale, even at the hard drive level. Because the system does firmware management, if the drive doesn't match perfectly it will not use it, AFAIK. Hence his fear and struggle to support the hardware.
