First time setup

Hello,
I am building my home NAS, my home does have 10gb networking throughout. I am currently waiting on parts for this,
13900ks (damaged due to Intel sucking only running low voltage and under 4.5ghz)
I’ll have 2 m.2 slots 4 sata with the ability to add cards.
Current drives
3x ironwood pro 18tb
1x 4tb gen4 Samsung 990 pro
1x 8th Samsung 870 QVO
1x Intel x520 T2
32gb Corsair dominator 6000Mhz (Edited)
My intentions are to use the HDDs in the raid 5 equivalent, and the 4tb NVME as cache for the HDDs, and probably just put the 8tb ssd as a solo drive for steam server download. I’ve never set up a home NAS to this degree. And recommendations or suggestions are welcomed. I have all of this hardware already aside from the motherboard and case, which is why everything is kind of all over the place. It’s what’s just laying around. I also have a 3090 laying around but I just didn’t see how this was going to beneficial. Correct me if I’m wrong, no I’ve never used truenas, but I’m very familiar with networks and windows servers.

My goal here is to have network storage that about 8 computers will backup to, while also having a drive for easy access to files. Eventually incorporate what home functionality but that’s far off.

Thanks,
Doc

Welcome!
Regarding your plan:

Is totally an overkill/watt waste for a most oriented storage NAS. Not considering u already know Is damaged. IMHO RMA It and then resell

For my little knowledge, if you mean L2arc, you should at least have 64gb of RAM (u don’t mention what RAM you will use) before think about it, and prob 4tb Is too much… But take this with a grain of salt waiting someone more expert

If you don’t use It (like for Plex/Jellyfin transcoding), better save watt with the integrated One

Hello,
Thank you for the response, I know the 13900ks is overkill but its what I have laying around without a purpose so I just figured I would limit its power and save some money without having to buy another CPU. I cannot RMA because it is a delid’d processor.
I was only thinking about using it as a cache because I assumed it would work like this. I go to back up my main desktop, 2tb, it would send it to the 4tb first then over time behind the scenes write it to the HDD’s saving me time on my desktop backup. All my other devices would not back up more than 500gb.

Sorry forgot the RAM I will add it, but it wil only be 32gb 6000Mhz RAM would I benefit alot more gettting 64? or 96?
I dont intend to use Plex so no GPU for me.

I can totally understand your point of view, as same i don’t agree with your final decision: let’s put aside all consideration about power and consumption… a damaged CPU in a system that MUST run rock solid Is a pretty bad choice.

Ok i think you probably were point to a slog more than l2arc, my bad

32gb are not poor, if you don’t use intensive apps. But the kind you have are not raccomended ( same CPU reason basically, power consumption and over heating)

:grin:

IMHO you highly risk to waste a lot of money tryng building your Nas on those parts, and at the end without having a reliable Nas.
Trust me, sell what u can and point to more appropriate Hw

Very valid points, damaged 13900ks when a nas should be rock solid. My understanding is (first timer here so I can absolutely be wrong) let’s say cpu fails, I change out hardware completely. Different board different cpu, I could then import the config and rebuild the raid pools without any data loss? The downside to this would obviously be the hardware is offline while I replace it.

I completely agree I should have ecc memory and the more we have this conversation the more I want to just buy a different board cpu and ram for the ecc alone.

As far as the 13900ks though, I’ve done allot of testing with it and windows, if I limit power and restrict frequency I was able to use it like normal even with avx instructions. But regardless you are spot on with trying to build a must function with hope functionality.

Thank you for the feedback.

Don’t use the 4TB as cache, it’s not suited for it and may actually lower your performance.
A SLOG is only ever going to store 2 transaction groups before committing the data to the data VDEVs, which in your case is unlikely to ever be more than 16GB. A SLOG is also only used for sync writes, not async writes. With default sync-settings a Windows client connecting with SMB won’t use sync writes. NFS transfers and MacOS SMB clients might.

The other type of cache, L2ARC, is also a poor fit for that 4TB NVMe. L2ARC needs RAM to hold some data and a drive that large is going to eat into your RAM big time. The guideline is to aim for an L2ARC around 5:1 to at most 10:1 of your total RAM, and don’t use it at all if you have less than 32GB RAM.

That is good to know. I wasn’t sure how the cache would work. Since it works like that I’ll probably just repurpose the 4tb nvme somewhere else for a different purpose.
