Depends on hardware generation. i just setup AMD Epyc Rome server with 3200MHz DDR4 - work by default, a this is recommended and supported RAM speed for this system.

great info. i searched for this in unraid docs, but found nothing similar..

Yes, i think you cant compare them at all. yes, both are software raids, but that's all..

then choose simple Debian or other standard Linux distro. with unraid array you can have up to two parity disks in whole array. more: https://wiki.unraid.net/Parity with latest unraid version you can have multiple cache pools - in various BTRFS raid levels if multiple drives are used. so no option to build other standard software RAIDs.

sorry, unraid is not raid, so if you plan use these with unraid, then newest version is not for you. and with unraid you get less but bigger drives - therefore again unraid is not raid.

First, it's all about the bandwith available. it's a PCIe 2.0 x8 card, so about 4000MB/s available. if you connect 40 drives, then about 100MB/s available per drive IF all drives used at once.

@SimonF Seasonic please

as i wrote, 4 drives to one Molex.. this is very typical..

huh, i purchased Seasonic Prime Gold unit recently, but could not find where to get additional cables. i needed Molex ones.. and don't use cables from another manufacturer PSUs - you can fire your equipment..

That's is why larger rack cases comes with backplanes - for example SM 846 have 24 port backplane and you power it with just 6 Molex connectors for all 24 drives. this is very common - 4 drives per one Molex. if you have case with no backplane, then yes, you must use some power splitters - and use them with same - 4 drives to one Molex. Yes No! dual EPS12v are not so common, but there exists another splitter to make PCIe cable to CPU cable - many consumer PSUs come with much of PCIe cables.

this is why i'm choosing 4U SM case: - to place bigger and more silent fans - my last SM case was 743 Series (sadly will not fit your EE-ATX), swapped out middle fans for 12cm Noctuas, removed read fan. - to use standard ATX PSU - 743 came with ATX PSU, fan is not so loud. for 3U i see 836 only, but again - noise is an issue in my use-case.. and for EE-ATX boards you cant use ATX PSU - no room for that..

i think you can start then with this - make a backup server for your data if they are worth for you.. or start building new one and leave existing one as backup server. and you are right - parity is not a backup, keep this in mind. SM cases are not cheap at all, and according drive sizes and price - here in Europe cost per TB are so close compared 4TB vs 16TB. with later you just need more investment at once..

First, why you need so many drives? are they any 16TB or so with high density? if no, then you can think of just upgrade your drives first. According a case - i have Norco 4224 for myself too, and it works very well for me. i'm on the way of downsizing now next question is a case backplane. if you have 9305-24i and pair it with Supermicro SAS3 backplane with buit-in expander and databolt technology, then you can get much more bandwidth and connect more than 24 drives with no loosing max speed for drives. just read carefully case documentation about a backplanes used - SM have much of them. if you choose 36 drive version, then there is two backplanes with builtin expanders, so you can use your LSI card with both of them. @JorgeB have very helpfull post with drive speed tests, see here

see my answer here:

i have only experience with rack-mounts.. with Supermicro 846 series, you can go up to 24 drives, like this one https://www.supermicro.com/en/products/chassis/4U/846/SC846BE2C-R1K23B with 847 series you can go to 36 or 44 drives, but this is a bit overkill.. these ones will be out of your budget, you can go cheaper, but build quality can't be compared with SM ones.. see this one for example: https://www.inter-tech.de/en/products/ipc/storage-cases/4u-4424 i recently got their 16-bay version, it just works, but as i said, SM ones is a different league..

what is your budget? how many disks would you like to connect?

sorry no Asus, but this one works well with my gigabit: https://mikrotik.com/product/rb4011igs_rm

mid of 2021 will be there very soon

huh, great tools are on free docker accounts - and according to new docker hub rules, all "unused" images are gone very soon..

if your images are still available on docker hub..

this sticky post wont help?

yes, full size in USB A port - this port is on motherboard..

i have negative experience with such config - you need very good airflow inside your case. my unraid usb started dropping offline time to time. i issued unraid key replace procedure, and new one drops again. after moving to outside, no problems so far.

if you wanna control them by unraid, then you must set Fan mode Full Speed on Supermicro impi side to avoid any confusion for concurrent controlling processes. and what is your goal? to control fun speed by HDD Temp?

please show your low thresholds, and FAN mode setting from Supermicro IPMI.
