I am going to buy an extra PCI-e 1gbE NIC and use bonding (with the one on the motherboard). But before I purchase one I’d like to know if there’s any recommendations on which brand or model that works best with Unraid? as the subject says it’s going to be bonded using IEEE 802.3ad. There’s no use in recommending NIC with 2.5gbE or 10gbE instead, because I’m not going to switch out all my network hardware. At the moment I only have a gigabit LAN and have no plans on upgrading all ubiquiti switches to support 2.5/10gbE. Got enough expenses playing with Unraid at the moment.

Im building a 24-disk (SATA 7200prm Enterprise HDD's) Unraid NAS that is only going to be used to download (save/write), store and play (read) media. All the "applications", like Plex, Torrent, Radarr/Sonarr.. you name it, will be on another NAS (Synology RS1619xs+) with enterprise SSD's. So all the Unraid server will do is act like a share for all other applications to access. Im planning on having 2 disks as parity in the Unraid server (doubt it matters, but i thought id mention it). So, im uncertain if i "need" a SSD cache pool in unraid or not. So i was hoping i could get your input on the matter. The biggest thing on my mind, and perhaps the biggest reason to creating this post, is whatever not using a SSD cache pool will greatly reduce download speeds from torrent-client since it writes to HDDs, if not using SSD cache pool. Now, granted this was a long long time ago, i remember when i used HDD's "back in the days" and used utorrent (that was the thing back then) there was a ton of issues/errors because the drives couldnt keep up. Cant remember the actual errors (or warnings perhaps), but it had something to do with "congestions" or something and i know that at that time it was solved with using SSD's to write (download) to and then movie it to the HDD-storage. So, is that still a thing? Do i need/is it recommended to use a SSD cache pool? Im pretty sure i had 7200rpm HDDs back then too.. Would greatly appreciate any help since im as new to this as a toddler is to the world. Its all very exciting, but also very scary and most of the time i have no clue on why things are as they are.

Ok thanks, that’s good to hear! chieftec got back now and said that there’s more cables available for purchase. But he also said: ”However, there is no more socket free to you to insert extra cables buying from us to PSU when I count the current power cables included in the box of the PSU.” I guess he means that it’s only 3 such connections on the PSU and if I use all of them for the backplane there’s no connections left for other things (like SSD cache pool). So I’m getting closer and closer to be an owner of a Corsair PSU.

Yes i hope so. ive contacted all of them asking if theres possible to buy more cables since all of them ships with only one cable (one or two had 2 cables), except corsair that seems to have three cables in the package. So far only corsair and adata has replied back. adata did not sell extra cables, so that PSU are out of the equation. I also removed the seasonic 1300W PSU from the list because $566 was a bit to steep a price for me. and 1300W on a single-rail seems not recommended either. Im waiting for a response on the others and see what i decide. but corsair is high on the list at the moment since it has all cables included. Tho my ignorance makes me a bit nervous about if the 12V+ 999.6W is enough to handle the spin-up. anyway, huge thanks for all the help so far! hopefully im not going to have to disturb you with any more questions.

Ok, well seems the Corsair RMx 1000W ships with three such cables. And if I’m wrong I have checked with their support and it’s possible to buy more from them. https://www.corsair.com/us/en/p/pc-components-accessories/cp-8920112/type-3-flat-black-peripheral-cable-with-4-connectors-cp-8920112

ok thanks for the suggestion! looks like it has both single-rail and multi-rail. but dont come with enough molex (peripheral) cables? seems it only ships with 2 cables with 4 molex on each. if i want to use 2 molex on each cable i need 1 more cable. Also seems like an EOL product? atleast over here it seems only one webshop has that PSU and one listed it as "discontinued". it costs around $290 (or 265 EUR or 225 GBP) on the shop that still has it.

Sounds like i need to really hope that some of those PSUs has enough cables or that i can buy more of them. Me learning all that and not making a mistake seems like risky business. if im not mistaken it seems like the "Corsair RMx 1000W" comes with 6 connectors on the PSU for sata & peripherals and ships with 3 cables all having 4 molex each. so that one should work for me without having to buy more cables. Atleast the manual states this so i guess its ok to use peripheral connectors on PSU for HDDs on this specific PSU: "5. Connect the peripheral cables, PCI-Express cables, and SATA cables. A. Connect the peripherals cables to your hard drive and CD-ROM/DVD-ROM power sockets. B. Connect the SATA cables to your SATA SSD or hard drive’s power sockets"

thanks for that explanation and clarification! while doing all the browsing, searching, googling, and looking around im pretty sure i read on a few places that its NOT recommended to use any other cables than whats shipped with the PSU (think it was in the context of buying a new PSU and reusing cables from the old/another PSU) or atleast buy the same cables from the same brand that are made for that specific PSU. And it seems i cant find any "acessories cables" for at least the first PSU on my list here, the "Adata XPG CyberCore II 1000W". Do you mean i can just buy whatever molex cable i want that has the same connector that fits in the PSU? (whatever that connection is)

Ok, so you mean i connect two molex from each cable (three cables) into the 6 slots. so each cable only has two connections going between backplane and PSU? Im not sure how to check if the PSU's ive been looking at has that many slots. Seems the only thing they state in the documentations are how many cables are shipped with the unit, and how many molex connections each cable has. Nothing about how many connectors on the PSU there is for connecting the cables for molex/hdd. Im guessing since they only ship one cable, theres only one connection on the PSU dedicated for power to HDD/Molex?

wow, i have been so occupied with figuring out which PSU i need in regards to watt. so i totally forgot that i actually need to connect it to the hdd's too haha (that or im so used to SSD's so i just didnt think HDD's needed the power connection). thanks for the reminder! im going to buy a Inter-Tech 4724 chassi that has a 6G 2x12-way backplane and if the spec sheet are to be trusted its 3x molex for "electrical connection". Not sure if its 3x for every 12-way (so a total of 6x molex) or 3 in total though. but my guess is that its 3 total. guess that means the PSU needs to have 3 cables for hard drives? And is it "molex 4-pin connector" i have to check for on the PSU? Like the "Adata XPG CyberCore II 1000W" says: Molex 4 Pin Connector 1000W：4 Cable Quantity: 1 But it also says some weirdness with the cables length, i think. They say cable quantity "1", but states four different lengths. Or perhaps its just so easy that its one cable that has 4 molex on it? i.e the left side of the cable on the image goes to the PSU and it has 4 molex on the other side that goes to the HDDs (in my case the backplane) So, for that PSU it has enough connectors, bu not enough cables? And perhaps even to short if it turns out it is only 15cm long Am i right in thinking that are the connectors i need to look for? not sure what you mean with the layout of the hard drive cables though?

Ok, so its the 12V+ number i have to look at? if thats the case, all of the PSU's have the exact same 12V watt as its sold as except a few: "Adata XPG CyberCore II 1000W", says it has 1300W on the 12V+ (not sure if this correct tho). "Chieftec PowerPlay Platinum Series 1050W" says it has 1000W. "Thermaltake Toughpower DPS G RGB 1000W" says it has 996W. "Thermaltake Toughpower PF1 ARGB 1050W" and "Seasonic TX 1300W" i couldnt find the 12V+ specs. "Corsair RMx 1000W" had 999.6W "EVGA G6 Gold 1000W" had 999.6W (83.3A, but they translate that to 1000W in spec sheets) And these had the same 12V+ specs as its sold as: "Cougar Polar 1050W" had 1050W "EVGA P6 Platinum 1000W" had 1000W "MSI A1000G 1000W" had 1000W "Thermaltake Toughpower GF1 1000W" had 1000W All of them was marked as Tier A (High-End) with yellow text (best in tier). So i guess i could take any of those. Just choose the cheapest ones.

ok, guess ill look thru that list that ConnerVT gave me. though, at a quick glance its a struggle. Like the single-rail Chieftronic Power Play Platinum 1050W, the specs says: +12V 183.33A +12V2 - +12V1, +12V2 combined 999.96W -12V0, 3A / 3,6W thats a lot of different 12V that i have no clue on which of those i need to look at.

yes, I understand more knowledge is needed to both explain and understand (since I can’t do neither lol). But how are we, the ignorant mass, going to be able to choose a PSU that can handle what we want it to handle (like in my case power everything and handle spin-up without staggered) without going back to school? and once again, the last part you added again about single-rail. You still make it sound like if I choose a single-rail I don’t have to check all the details about 5V/12V and just choose a PSU with +900w and it will work fine. And only if I choose to buy a multi-rail I have to check for those specifications. Is that correct or am I (once again) misunderstanding? If so it seems single-rail is the way to go for me so I can be sure it works.

Sorry, you kinda lost me there. im thinking about buying either Seagate Exos X18 18TB or 16TB. Or perhaps Seagate Exos X16 16TB. I might even go lower, to 12TB, but on the same models, depending on price at the moment when purchasing. Also checked some on the WD UltraStar DC HCXXX-models in different sizes. At least those seems to be among the best ones when looking at Price/TB over here. And its those ive checked to get the watt usage at spin-up (took the ones with the highest watt usage, i believe it was the Seagate Exos X18). Though i cant seem to find that information about 5V/12V power figures. Or i dont know what to look for. And im still not sure if i understand it right. you mean the total power isnt something i need to care about for when choosing a PSU so it can handle the spin-up? As far as (i thought) i knew the spin-up was the moment when the most amount of power was used and you "had" to choose a PSU that could handle that amount of wattage, if i dont want to use staggered in unraid. Sorry if it all sounds dumb, having a hard time grasping what it is need to check for, to be able to have the PSU handle to boot it all up without staggered and just .. well.. power the thing without issues. EDIT: i found this about the Seagate Exos X18 (and that is what i used to calculate spin-up power) Startup current (typical) 12V (peak) 2.6A 2.0A (optional configuration through Smart Command Transport) But as i said, found nothing about 5V.

thanks you wonderful people for explaining it to me. So if I understand correct that means that if I choose a single-rail that is +900w (can handle the max load of 879w at spin-up) I don’t need to check the load for hard drive supply lines? (Not that I know which line is for HDD) I checked the EVGA supernova g6 1000w and it says it has 105w on the +5V. But the HDDs draws 749w at spin-up. So, that shouldn’t matter then since it’s a single-rail UPS?

Thanks for that list! I’ll go thru that list and see if I find something I like. What’s your opinion about the single-rail va multi-rail? And regarding 5v power?

Looking for a PSU for my unraid build but having a hard time figuring out what to buy. I know that I will need at least a 900w if I'm not going to run staggered in unraid (so it can handle spin-up of all drivers simultaneosly) and not lower than 700w if I'm going to be around 50% in load (i assume that is whats optimal). What I don't know, however, is whether it "must" be single-rail, if it's a strong recommendation or if I can just ignore that and buy whatever. Also i have been trying to find out if the PSUs I've looked at are single-rail or not, but haven't found a single PSU on any of the major webshops (at least here in sweden) that advertise whether it's single-rail or multi-rail, etc on the product pages on the webshops.. Also, I read something about buying a PSU that has enough power at 5V (because the HDD uses it during spin-up/boot or whatever.. can't remember exactly why, was something with the HDD anyway). Even this information seems hard to find about the PSU's. I might add that all these "suggestions" ive found here at the unraid forums. So, now im hoping that there is a veteran in unraid who knows about this or someone who knows PSU (or maybe both) and can guide me to a PSU purchase, but above all perhaps answer the questions regarding the single-rail and the 5V thing at least.

I’m thinking of buying this rack chassi: Inter-tech 4724 but I’m really struggling with figuring out what exactly I need to connect the backplane to the motherboard (haven’t decided on motherboard yet). I’m guessing HBA but no clue on how many or which of them, or which cables (or how many) and if I need something more/else. Been trying to find info about it but either I’m dumb as a brick or I just can’t find the (right) information. what i could find was this: * The chassi has 2x 12-way S-ATA/SAS hot-swap backplane with 3x SFF-8087 socket. * The backplane is only suitable for operation on a SAS controller with a SFF-8087 connector. * Adapter cables are required for controllers with other connections. * For operation with a SATA controller, please order the corresponding number of the optional crossed SFF-8087 to 4x SATA cables (88885237). But what that means i actually need I have no clue. So, now I’m here putting my faith in the experts here in the hopes of someone that could tell me what I’d need. And hopefully I’ll learn something in the process.

ive outgrown my 8slot, 5slot and 4slot NAS'es. And realized that using a lot of different volumes isnt optimal for radarr/sonarr. So im looking for good rack-mounted enclosure that fits 24+ HDD (or 72) that can use motherboards and sas/sata cards that works great with unraid. so, something like supermicro and the likes.. I just dont want to feel that im running out of space anytime soon. anyone has suggestions? (im from sweden, so id prefer if i got suggestions on enclosure that i actually can buy and not only available to US customers etc..)
