I need support for HDD connection and config

Hi for all

Which is the best solution to connect and cofing 100 pcs HDD 16TB SATA 3.5 to one PC. they are with plots just i need for farm, and I dont want to use harvester

I need best soluton for hardwer that i can connect them

Thanks

Read here, I went usb, and its a pita, bad lookup times.
I’d check with the OP of thread first, but I don’t believe they have issues with lookups.

Nope, no issues at all! I have recently split my farm into 3 harvesters but it’s mostly because I wanted to learn about independent harvesters - I knew I couldn’t scale indefinitely on a single PC. But at one point I had a single old PowerEdge controlling over 100 SATA drives!

Thank you very much for your feedback

@enderTown how did you connect over 100 SATA drives on PowerEdge, I have PowerEdge R740xd but it has only 18 sata port, I cant connect more 18 pcss HDD on this Server.

I have 6 pcs dell servers R740xd on each one I have installed 18 pcs HDD but I want to remove 5 pcs server and to use only one server that I can install all hdds on one server,

Please let me know which controller I can use on this server to connect over 100 SATA drives

Thank you in advance

My issue, sorry for of topic, but kinda related.
I can farm for 18 hrs with no issues.
But occasionally I get warnings for looking up qualities.
It only happens if I get more than one lookup within 1 second.
I dont understand why I’m sometimes searching my plots 7 x within 1 sec to look for proofs when block times are apx 10 sec apart.
At this point I’m not sure if it’s my usb setup, or chia software forcing me to check to often for some crazy reason.
But I’d advise new ppl to avoid usb till I know more.

Our of curiosity, if you don’t mind sharing the info or pm me ( understand if you want to keep it pvt ) .

  1. Are you pooling? I believe difficulty could stop my issue by reducing checks.

  2. What’s your capacity in TiB? I’m at just over 500.

Edit.

@artwise it’s all in the thread, but maybe you’ll be lucky enough to get the answers without digging.

Thank you for your feedback and your support.

Those are great servers! Mine was an older R620, so you should great performance on those newer servers. I use PCI-E SATA add-in cards that support Port Multipliers. Each port from the add-in card can be connected to a port multiplier and each port multiplier can then control 5 SATA drives. The port multipliers are cheap - this is “poor man’s SAS” lol. More details in the thread linked above!

Sure! With this setup I’ve currently got the same - just over 500TB. I’m at about 130 4tb SATA drives shared between 3 harvesters. The harvesters are old used Dell Optiplex small-form-factor PCs. You can get them for $50-100 on ebay. They are more powerful than a Raspberry Pi and also include 2 PCI-e slots for the SATA expansion/port multipliers OR PCI-e USB expansion cards. You probably would get better/more stable performance by splitting your farming into at least 2 harvesters, and once you get past the first harvester configuration, adding more harvesters is easy!

And I’m both pooling and solo’ing, about half and half right now. Once I totally fill my disks, I start replacing OG plots with NFT plots until I get more disks. :slight_smile:

Many thanks for that.
I’m sure pooling and difficulty would stop me searching multiple times in a second.
It’s not the route I wanted to take, but I’ve stopped plotting while I fix this, and I’d rather be growing again.

If you were all solo, it’d be more comparable, but I’m nearly 50% nft plots and if pooling let’s me grow I’ll bite the bullet and try it.

If you have extra $$ and want to get professional grade equipment, then SAS is the way to go:

This JBOD can host 24 SATA drives and it connects to your farmer directly through a SAS cable (you will need a PCIE expansion card for it). There are more costly JBODs that can contain up to 90 disks in one unit! But they are very expensive.

Also when constructing system from JBODs from same manufacturer, usually you can “daisy chain” them, such that up to 5 of them can be served from a single SAS port.

Other manufacturers offer USB JBODs:

Dear
Thank you very much for your feedback

Is it possible to put hdds and configuration on jbod without lost data, because i have full hdds with plots, hdds are non raid configuration.

Thanks

Yes, if non raid, that will work.
But older jbod will not work with 16 tb drives.
I dont use jbod, I believe sas2 or sas 3 would work, but don’t take my word, research or wait for another more knowledgeable person.

Thumbs up for sas-solution when using more than 16 drives.

Pros:

  • rly cheap when buying used ones on ebay
  • no USB-limits
  • usually built-in cooling
  • easy powering and cable
  • space-effective

Cons:

  • mostly loud because of cooling
  • require additional HBA-card
  • not possible with raspberry
  • expensive when using less than 16 drives

I use JBOD sans digital. Spec says up to 12TB drives, but it is just old documentation - maybe at that time this was largest capacity. In reality I use it with 18TB drives no problem.

And JBOD doesn’t impose a particular RAID configuration. It is up to you how to build it and depends on the expansion card controller. By default these cards are “flashed” in non-raid mode (so each disk will operate individually).

When it comes to 100x 16TB drives, it costs like $30000 retail. If you want them to last, you should not make some janky rig with home made components. It would make sense if you get HDDs for dime a dozen - so if it breaks, no big deal. But lots of 16TB drives are a big deal.

Hello, Can you remember back in 1985 when we only had 5mb hard disks (ST506), we have come a long way!!

I have a perfect solution.
