I won’t know definitely until tonight. So what are my options if I do and if I don’t

Why wouldn’t it be supported?

So in my installation, I have Xen Server installed to a flash drive then i have my raid storage added as a SR.

I’m hoping the issue is just with the flash drive.

@Danp hardware as far as the raid controller? Be specific if able

Noticed that when I tried to login to the server,
It was having an issue. I rebooted, then these two lovelies came up.

@Pete-S you may missed it but I have 2 newer servers R530's. The R710 (or even a R720) would be there basically to be a point to back up to while I fix the storage situation. Power cost is a big deal but its one that is a moot point in my situation. I of course would put new disks in it. The point of the 3rd server would only again but for barely if anything but just a way to push my vm's to it while I deal with the storage situation of the actual main servers.

I actually have an older Power Edge T110 i, but I took it off site. So if it weren't for that I'd actually be using it in the place. The R710 (or 720) are both way more powerful than what I have available. I'm not trying to have anything but maybe 2-4 vms running anyways, and they aren't powerful vms. Were talking AD, FS etc.

Otherwise I need some major help on trying to get what Scott is saying I need done. I think Scott hit it on the head, I just don't know where to start.

@taurex said in Ubiquiti NVR Performance Improvement:

Are you recording most of your streams at full 30 FPS? Are you able to reduce it to 15 FPS and record motion only? This should cut down Unifi NVR's IOPS quite a bit.

I didn't think about changing the FPS, yes I'm noticing my NVR is THE Biggest talker on the entire network.

Create a new SR? Wouldn't that break something? I'm confident when adding a single or more hard drive to the SR. I'm not very confident when we talking about the RAID it doesn't seem to make sense.

@scottalanmiller on one of our servers it's properly done. One the other not so much. I'm going to get the dell engineer I originally worked with to fix the one that isn't working right. So when we use Dell's tool to look at the raid it shows the proper capacity expansion on one server. The other server doesn't show the increase.

When I go into Xen Center, it doesn't "dynamically" see the adjust space. So I see what you're saying I was hoping it would automagically be there, not the case. So how do I get it to add it?

@notverypunny I mean after looking around on the net I see what Scott is saying the better performance might actually be better with thick provisioning, but it's negligible when people run analytics on it vs thin. Like only a couple of %.

But I think I see what Scott is also saying that maybe one of the HDD's if possibly throwing errors or failing. I've already replaced 2 drives in 2 years.

@notverypunny See I want to get on the latest and greatest release. I just want to avoid having to nuke everything.

@scottalanmiller I also recall you telling me years ago, that there was a limit to how many hard drives (spinning rust) I could add to a raid 10 depending on if I was looking for a boost in either read or write. If I recall, read was the only thing that would speed up.

@scottalanmiller so what should I do?

@Pete-S that I can do.

Technically right now the host is 16 Tb raw storage and 8 Tb usable (maybe a notch less) since it’s raid 10 but the XenServer HVM doesn’t see the extra 4 Tb yet. I dunno why 🤨. See I’ve done capacity expansions before on other additional single drives no problem. But on the raid I’m lost. Since it was “added” capacity from bios, I assume the hyper visor would just “see” it.

@DustinB3403 yea I know it’s not a lot. We are a somewhat small non profit. Honestly I would rather max out both servers ram wise and switch to all SSDs since the price is literally the same for Nearline SAS.

I’m assuming the thin provisioning is the culprit but that’s only an assumption. I recall reading that it would slow down in time vs thick provisioning being a bit speedier.

Im thinking of getting a 3rd server that can just have enough storage to move my vm's over, then nuke the old host one by one or upgrade them. I'm not sure if 7.1 is upgraded to the XCP-NG releases.

@DustinB3403 Yea because I've seen all the advances made on 8 release, so I anxiously want to move to that. But I know until I can get another server here its a bit tough.

@DustinB3403 so my original installation of Xen Server was to 4 disks, raid 10. When we added the additional 4, dell did a "live" update to the raid configuration so that it added the capacity. That part looks fine but then from Xen Server I'm under the "assumption" it will see the Raid has changed automagically and expand but alas it didn't

So your saying I need to add a new SR? Is that different than expanding the existing one?

@DustinB3403 I started back using Dell Live Optics, I need to finish adding it to each VM server so we can determine the performance characteristics. I'm just deeply assuming the thin provisioning is the culprit but that's without proof, only assumptions.
