If you were to suddenly come into possession of 12+ enterprise-grade SAS hard drives, how would you go about incorporating them into your homelab?

  Sell them and buy low budget low power consumption disks that would fit my purpose.

  Enterprise-grade usually has enterprise-grade power consumption. From the power saving alone you can buy nice stuff.

    This is a great observation, and it made me do some math:

    If my point of comparison is something like a seagate ironwolf 4T vs a WD Ultrastar 4T:

    Seagate Ironwolf: 
    - 3.7W*24 Hours/day*635 days/year = 32kWh per year * $0.18/kWh = $5.84 per year in power usage * 12 disks in an array = $70.02 per year
    
    WD Ultrastar:
    - 7W*24 Hours/day*635 days/year = 61kWh per year * $0.18/kWh = $11.05 per year in power usage * 12 disks in an array = $132.6 per year
    

    Seems like i’d save maybe $70 per year. I feel like that difference might even be justifiable if the enterprise drives are half as likely to fail (seagate ironwolf has an AFR of 0.87%, WD Ultrastar is 0.44%).

    Something to think about, at least

      635 days is a fucking long year.

      In defence, the power prizing here is a tad different, €0.45/KWh was the prize here. Also, when those disks are given away, they are usually smaller then the current standard and less efficient. On the other hand, those enterprise grade disks generate some heat, saving on the heating bill.

    Please do not sell used enterprise hard drives, especially if you got them from your empoyer. This is how those emberrasing company secrets get leaked and we can’t have that can we? :)

      Then those disks should have been wiped at the company before they were allowed to leave the building.

  Sell. I don’t run a data center and I’m not a cloud provider. I have a meager home server with some stuff plugged in and serve some tv shows. I want this to be as low foot print as possible. If it goes over 10w idle, I’m shutting it down lol.

  • Blue_Morpho@lemmy.world ⁨9⁩ ⁨months⁩ ago

    If I remember correctly, every watt is around $1 a year. So a 100 watt server costs $100 a year every year to run. 12 SAS drives and the server is going to be expensive to keep running.

      1W would be 8.769kWh per year. Pricing is regional.

    Damn 10watts? My server has a 5800x in it(my old cpu) and I have never seen the system pull less than 130watts

      Yeah a lot of people will say to just use your old PC thats lying around and it is a great way to start and learn but if you want something with a lower footprint (low power, quiet, cool) you’re better off buying something more suited to that task. Laptops or mini PCs are much more suited to that.

      Id love to have a server rack one day but I just cant justify it drawing so much power and I can live with the drawbacks of a smaller server.

  • jkrtn@lemmy.ml ⁨9⁩ ⁨months⁩ ago

    What’s your hardware? 10w sounds great to me. I just started a new build and have to play around to see if I can get better C-states while idle.

      11th gen NUC. Much faster than a RPI4, more power if needed (for things like Zigbee USB adapters, external drives…) while still maintaining low power draw on idle. Neofetch Temps

  You don’t say what the capacity is or how old they are. They might not be worth using.

  I would haunt eBay for an old file bay, such as an HP Proliant or a NetApp, then get an HBA card, and hope there is a spot in my house that isn’t going to be bothered by the noise. There’s a seller called theartofserver on eBay that repurposes old enterprise grade stuff for self hosting use, and I got a card that connected a NetApp file bay to my old 4th gen gaming rig, and that’s where all my files live now. I’ve lost a few drives over the years, but no files.

    Haha crazy to randomly come across that name on Lemmy. I bought a bunch of the parts for my NAS/Proxmox server from that seller a couple years ago.

  No matter how you go about it, getting these drives set up to be reliable isn’t going to be cheap. If you want to run without an enclosure, at the very least (and assuming you are running Linux) you are going to want something like LSI SAS cards with external ports, preferably a 4-port card (around $50-$100, each port will run four drives) that you can flash into IT mode. You will need matching splitter cables (3x $25 each). And most importantly you need a VERY solid power supply, preferably something with redundancy (probably $100 or more). These prices are based on used hardware from ebay, except for the cables, and you’ll have to do some considerable research to learn how to flash the SAS cards, and which ones can be flashed.

  Of course this is very bare-bones, you won’t have a case to mount the drives in, and splitter cables from the power supply can be finicky, but with time and experience it can be made to work very well. My current NAS is capable of handling up to 32 external and 8 internal drives and I’m using 3D-printed drive cages with some cheap SATA2 backplanes to finally get a rock-solid setup. It takes a lot of work and experience to do things cheaply.

    Why immediate jump to IT mode? Sure ZFS is great but running ZFS takes a decent chunk of RAM for cache.

    source

    • Shdwdrgn@mander.xyz ⁨9⁩ ⁨months⁩ ago

      What do you consider a fair amount? My current server has 64GB of ram but arc_summary says ZFS is only using 6.35GB on a system with three ZFS pools totaling over 105TB of storage under pretty much constant usage.

      source
• CalicoJack@lemmy.dbzer0.com ⁨9⁩ ⁨months⁩ ago

  I would sell a few of them to shore up the budget, then use those funds to build a NAS box. You can buy everything other than drives for a few hundred, less if you have spare parts sitting around.

  source

  • archomrade@midwest.social ⁨9⁩ ⁨months⁩ ago

    I think this might strike the right balance.

    I kinda get where everyone else is coming from, about enterprise grade drives being more performance than needed, but with the reliability of these drives it just doesn’t make sense to me to get rid of them all. The power use difference between these and other NAS drives is pretty negligible, and the parts needed to utilize a SAS array aren’t all that expensive in comparison to buying new drives (even if I sold all of these, I don’t think i could get as much for them as what even a used consumer drive would be).

    These are 4TB drives, so an array of 4 in a raid 5 configuration would get me 12 TB. I could go up to a more redundant raid with more disks, so maybe I’ll get a shelf/case that can hold 6 or 8 or even 12, and plan for adding more later. I have a high-efficiency micro-atx sitting on my desk with a couple empty PCIE slots, all i’m missing I think is a SAS controller and a case/PSU.

    I’m always hurting for more space, so to me it’s smart even just to have them sitting on a shelf for when I need another.
