Hopefully that doesn’t happen soon! I don’t have too much room for more flash, lol.
But, I have quite a bit of available space, so, there shouldn’t be any concerns. Also- tomorrow, after a few adapters arrives, I’ll be adding another 2x 1T flash drives my Optiplex 5060 SFF.
The first screenshot is of Dells built in system tools for servers. Being a Dell server he should have Dell’s iDRAC, which is a lights out management module. It is really fantastic.
Each NVMe uses 4 lanes. For each of these x8 slots, they have two NVMes, for a total of 8 lanes.
The x16 slot already has 4x NVMe in it, lol. The other x16 slot has a GPU, which is located in that particular slot due to the lovely 3d-printed fan shroud.
One of the other full-height x8 slots also has a PLX switch, and is loaded with 4 more NVMes.
It’s completely full of spinning disks. Flash would be less power usage, but, would cost significantly more, and would end up being drastically more expensive.
Do you have any trouble with cooling or anything with them? Got like a billion unused PCIe lanes in my Dell R730 and can think of a few things that might benefit from a big NVMe ZFS pool.
I dream of this kind of storage. I just added a second m.2 with a couple of TB on it and the space is lovely but I can already see I’ll fill it sooner than I’d like.
The two ZFS pools are only 4 devices. One pool is spinning rust, the other is all NVMe.
I don’t use raid 5 for large disks, and instead go for raid6/z2. Given z2 and striped mirrors both have 50% overhead with only 4 disks- striped mirrors has the advantage of being much faster, double the IOPs, and faster rebuilds. For these particular pools, performance was more important than overall disk space.
However, before all of these disks were moved from TrueNAS to Unraid- there was a 8x8T Z2 pool, which worked exceptionally well.
I think I’m at 7x 18tb drives. I’m slowly replacing all the smaller 8tb disks in my server. Only 5 more to go. After that it’s a new server with more bays and/or a jbod shelf.

Having a large flash pool really makes your life so much better.
Until you fill up all your space and have to buy more :p

Good bot
Good bot
Fantastic bot, honestly.
Well this seems to be a good problem to have hahah. If you need to get rid of some of those ssds count with me.
ebay! You can pick up these “used” enterprise NVMe and SSDs for CHEAP. All 10 arrived with less than 5% wear.
What software are you running on all of this?
From https://lemmyonline.com/comment/768355
A bit of everything. Publicly facing websites. Lemmyonline.com. A few popular discord bots.
Linux ISO collection and streaming.
Lots of automation.
Lots of things around software development. Lots of things around systems and network administration.
Some kubernetes too.
A bit of everything, and nothing in particular.
What management interface is that though and is it part of the OS? What OS are you using anyway?
The first screenshot is of Dells built in system tools for servers. Being a Dell server he should have Dell’s iDRAC, which is a lights out management module. It is really fantastic.
I wasn’t talking about that. I was talking about the second screenshot. Thanks anyway
The bottom screenshot, is from proxmox, which is the top-level OS in play.
Ah okay. Maybe I should try that at some point. It’s been years since I used it last.
I honestly just started using it again a week or two ago. I have been extremely pleased with the features it offers.
The only problem I see is using 8x slots instead of 16x slots for double the storage
Whats the problem?
Each NVMe uses 4 lanes. For each of these x8 slots, they have two NVMes, for a total of 8 lanes.
The x16 slot already has 4x NVMe in it, lol. The other x16 slot has a GPU, which is located in that particular slot due to the lovely 3d-printed fan shroud.
One of the other full-height x8 slots also has a PLX switch, and is loaded with 4 more NVMes.
Does the plx introduce noticeable latency, and does it get hot?
I want to get a few, but I don’t really have the airflow you do, so I’m a bit worried.
I have not noticed any issues with it.
And- prior to Jan of this year, I used two of them in an r720xd because it didn’t support bifurcation. And- can’t say I ran into any issues.
I also, have not checked to see if it was hot either though.
If that’s a problem then I don’t want to be solved.
Its only a problem when you get the electric bill! (Or the wife finds your ebay receipts)
I doubt these use much power compared to their spinning rust anticedents.
I meant my general electric bill. My server room averages 500-700watts.
Was curious how many watts this machine pulls? Also curious if you had ever filled it will spinning disks - would flash be less power hungry?
This one averages around 220-250.
It’s completely full of spinning disks. Flash would be less power usage, but, would cost significantly more, and would end up being drastically more expensive.
Do you happen to have a link to those cards?
Dual Slot Bifurcation Card Those are the ones I just picked up.
If you have a x16 slot, and can fit a full-height card, and use 4x4x4x4 bifurcation, the ASUS Hyper M.2 is really good.
Sweet!
I’ve got a gen3 hyper M.2 but I was looking for something for the 8x slots in one of my servers without needing full height cards.
That’s the exact use case I got these for
Do you have any trouble with cooling or anything with them? Got like a billion unused PCIe lanes in my Dell R730 and can think of a few things that might benefit from a big NVMe ZFS pool.
Generally, no.
I run a custom fan control script which keeps the fans around 30% minimum, but increases if needed.
Below 30% some things were getting toasty
I dream of this kind of storage. I just added a second m.2 with a couple of TB on it and the space is lovely but I can already see I’ll fill it sooner than I’d like.
I will say, it’s nice not having to nickel and dime my storage.
But, the way I have things configured, redundancy takes up a huge chunk of the overall storage.
I have around 10x 1T NVMe and SATA SSDs in a ceph cluster. 60% storage overhead there.
Four of those 8T disks are in a ZFS Striped Mirror / Raid 10. 50% storage overhead.
The 4x 970 evo / evo plus drives are also in a striped mirror ZFS pool. 50% overhead.
But, still PLENTY of usable storage, and- highly available at that!
Any reason you went with a striped mirror instead of raidz5/6?
The two ZFS pools are only 4 devices. One pool is spinning rust, the other is all NVMe.
I don’t use raid 5 for large disks, and instead go for raid6/z2. Given z2 and striped mirrors both have 50% overhead with only 4 disks- striped mirrors has the advantage of being much faster, double the IOPs, and faster rebuilds. For these particular pools, performance was more important than overall disk space.
However, before all of these disks were moved from TrueNAS to Unraid- there was a 8x8T Z2 pool, which worked exceptionally well.
Cripes I was stoked I managed to upgrade from 4x 2tb to 4x 4tb recently.
I dont see any issues!
/me hides his 16 4tb 12g SAS drives…
I think I’m at 7x 18tb drives. I’m slowly replacing all the smaller 8tb disks in my server. Only 5 more to go. After that it’s a new server with more bays and/or a jbod shelf.
That’s my next step. I have 8 8tb drives I need to start swapping, 2x512 NVMEs for system/app cache, and 1 2tb NVME for media cache.
I’ll gladly take those problems out of your hands for free
Wondering what software you’re running to have all the storage managed and then your containers and things on top? Is it all on the 730XD?
The picture of the GUI at the end is Proxmox.
Proxmox is really powerful and great for a few servers.
I don’t see any problem here…
There are no free PCIe slots left! That is a huge problem!
This does seem like an issue, I can help you free up some PCIe slots if you’d like
Is your problem that you are bragging about your drives?
I’m out of room to add more drives!
Every one of my servers is basically completely full on disks. I need more servers.
I need some drives
Love this. Apart from hosting an instance, what are you using it for? Self-cloud?
I host a few handfuls of websites, some discord bots.
I hoard Linux isos. I use it for general purpose learning and experimentation.
There is also kubernetes running, source control, and a bit of everything else.
Amateur data hoarder here; teach me your ways
Backups backups backups.
Anything you don’t want to lose, follow the 3.2.1. rule.
Snapshots / Raid are not backups.
Also, unraid is fantastic for handling bulk media. ZFS is fantastic for keeping things safe. (and fast).
And ceph is great for squeezing 20k IOPs out of 6 million IOPs worth of enterprise SSDs!
