I can’t say for sure- but, there is a good chance I might have a problem.
The main picture attached to this post, is a pair of dual bifurcation cards, each with a pair of Samsung PM963 1T enterprise NVMes.
It is going into my r730XD. Which… is getting pretty full. This will fill up the last empty PCIe slots.
But, knock on wood, My r730XD supports bifurcation! LOTS of Bifurcation.
As a result, it now has more HDDs, and NVMes then I can count.
What’s the problem you ask? Well. That is just one of the many servers I have laying around here, all completely filled with NVMe and SATA SSDs…
Figured I would share. Seeing a bunch of SSDs is always a pretty sight.
And- as of two hours ago, my particular lemmy instance was migrated to these new NVMes completely transparently too.

Good bot
Fantastic bot, honestly.
Good bot
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 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!
Cripes I was stoked I managed to upgrade from 4x 2tb to 4x 4tb recently.
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.
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.
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.
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
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.
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
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 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.
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 bottom screenshot, is from proxmox, which is the top-level OS in play.
