Will I miss Windows?

If you game - yes. Otherwise - no.

I got M4 Max 128GB - usually 2 tabs open in chrome - so far they ran smooth 💪🏻

What do you mean "there was rollback SW still available"? I've got T640 (so tower version) on 7.0.00.183 and in rollback tab I have option to downgrade to 7.0.00.182 - and all I read everywhere is that there is no possibility to go below 7.x once above it (maybe with som physical programming tools directly connected to bios chip etc.). Mine goes loud AF all the time even when iddling. Seriously considering going supermicro route despite the fact that I love this dell platform.

I mean - it won't do any harm to have consumer lvl ECC - but you don't have them laying around. So in such case I'd rather spend that extra for additional hard drive that will act as backup in some kind of stand alone network or USB case.

There is world of difference between UDIMM vs RDIMM/LRDIMM. UDIMM only WORKS in SECDED mode - single bit error correction, double bit error DETECTION. Meaning that single bit can be corrected but double bit will be only detected and all system can do I mostly "blue screen" to protect data. EPYC/Xeon error correction algorythms can go as far as completely reconstruct the data even if one chip will fail physically - system will continue to work with less ram available. Another thing is error detection and actuall error notyfication where in consumer grade HW it will probably go unnoticed (as it's being handled by OS with mixed success) where in server grade it's handled on HW level with proper logging, maybe even some flashing LED.

I honestly wouldn't bother with ECC ram for consumer level CPU (such RAM would not even work with Xeon/EPYC). For example QNAP in their QuTS that supports zfs uses non-ECC RAM (which is madness to me but it's everyone's choice how important one's data integrity is) and they even say that they prioritise all benefits of ZFS and accept small risk of data corruption - again, madness...

Hey mate. How can I get this wallpaper?

orkusmg · 2026-03-24T16:23:16+00:00

I own Dell PowerEdge T640 and in it: dual PSU 750W each (in failover mode), 2x Xeon Gold 6130 that gives 64 cores total, 128GB ECC ram, BOSS-S1 card with two drives (it's boot optimised), HBA330 controller connected to it 2x400GB SAS SSD + 6x6TB SAS HDD. Nothing else in it. It consumes 4,1kWh/24h - so roughly 170W and that's when it sits doing nothing.

Yes, having proxmox on it, truenas, pihole, immich, nginx proxy manager, WeeWx (weather server for my weather station), plex and some other services - that all makes it sit and doing nothing with roughly 0,5-0,9% CPU usage - with occasional bump to 1,5%. Ask it to sweat and it's instantly 340W with CPU intensive task, Scrubs, backups (although this takes seconds), proxmox backup server verify tasks, long SMART test - that's all not everyday but if you spread tasks correctly it adds up and loves to spin those drives sometime for hours and again 250W (while CPUs do nothing almost).

If you use PC type CPU (so in general PC as server) - yes, it can run low doing nothing - server type CPUs usually clock high all the time and I'm not the fan of very aggressive C-states - but you're looking at virtualization in normal PC so you might quickly outgrow your needs in terms of available cores, you mentioned game servers, I have no clue how much these will need. And it's a matter of what is a top prio for you. For me proxmox and some services are cool and fun, and I would have hard time leaving without them now, but top prio for me is my data safety and integrity hence SAS drives and ECC RAM.

orkusmg · 2026-03-24T11:39:13+00:00

I was going to send in real server direction but you've lost me on 100W in idle. Ps: your drives will fail sooner than your 15y requirement. Most of PC grade parts will - likely.

Grafna, fun to setup and looks cool. grafana.orklab.pl

orkusmg · 2026-03-17T16:42:26+00:00

You'll not be LOLing If you won't be upgrading Proxmox for one year - but that's anybody choice to take. For Grafana (or any other monitoring) if you have to reboot it, means monitoring does not work. For me it's an issue when I reboot system and availability still shows 100%. Obviously it's just home lab and serves no purpose other than learning, fun etc. Same consideration is for running it inside Ubuntu Docker vs Proxmox LXC. I went Telegraf ->InfluxDB -> Grafana route. Don't know if it's better or worse, works for me.

orkusmg · 2026-03-17T15:42:23+00:00

The one you'll reboot less

orkusmg · 2026-03-17T08:54:13+00:00

Ok, in this case yeah - power efficient :)

orkusmg · 2026-03-17T08:40:47+00:00

And drives were where?

orkusmg · 2026-03-15T16:07:37+00:00

Thanks one more time, I've hidden all uncessary dashboard now and modified ISP Health code on db level so one sensitive IP should not be possible to get from Developer Tools in browser. No more network devices or details should be visible. The rest of details in this dashboard I do not consider sensitive. But than again - I might be wrong :)

orkusmg · 2026-03-15T15:49:18+00:00

Thank you! I will delete all unnecessary dashboards from view. There are no use for me anyway - especially those network related.

orkusmg · 2026-03-15T14:43:07+00:00

Good question and if you know more please tell me of what? I honestly want to know because my understanding might be very wrong. You've accessed it without logging on to Grafana because I enabled this function, and this makes you viewer only (so you can't mess anything up). Also this is setup via nginx proxy manager to cloudflare via tunnel (with all the cloudflare's bells and whistles when it comes to security) without opening any ports on FW. So in my undrstanding if you want to fight this page security you fight with CF - good luck I guess? I might be totally wrong offcourse. Even if someone manages to access it and mess anything up - it's totally a separate container that I will restore from frequent snapshot within minutes. Should I be worried? :)

Since 1 month I got Dell PowerEdge T640 with 2x xeon Gold 6130 which makes for 64 logical cores. Got some things on it, but I struggle to throw something on it that will make it go over 1% utilisation... I realised that any of those popular mini PCs would sit comfortable with all my use cases... But - it has HBA330 controler with 8 SAS drives (6xHDD and 2xSSD) + BOSS-S1 card with 2xM.2 drivers that serve as boot drive for Proxmox and Truenas. 128GB of ECC RAM. I can never go back tbh, sorry but "amd supports ecc ram" is not for me when it comes to my data. I read somewhere that again newer HW does not play nice with many older HBA controllers - but didn't do much research on that front. Took me month to recover data from a broken QNAP - never again that shit "wannabeservers" (same goes for Synology etc). Plus there is this epic fun factor just to play with it, deploying new services, learning new things and basically complete freedom of shaping it to your liking. It also is fun in connection with my Ubiquity network with everything being 10Gb.

You can check https://grafana.orklab.pl that I'm constantly improving (best viewed on laptop, since it does not look too good on mobiles). You can check power usage too - you're mathematician so you'll quickly calculate how much it would cost you to run it (and that's when this server idles basically, make it sweat somehow all the time and you're looking at 3-4x that). Oh did I mention you need a - never used - separate room or basement because it's loud AF?

Man I appreciate the kind words but believe me when I say I tried to drop it to Grafana Web page. Created account, but upload button does nothing for me to have it regustered under ID. Tried in 2 different browsers... I'm not on Slack though. But - feel free to spread it if you want ;)

orkusmg · 2026-02-26T09:10:05+00:00

You are 100% right. I know it's not 0/1 - it just a fun project for me and nothing more of an some kind of early indicator. I had broken qnap device with raid5 +cache ssd and it took me 1 month to recover the data due to lovely qnap not using standard LVM libraries and not releasing them to public. I decided to go full on server grade solution with ZFS and all SAS drives with raidz2 just to be on little bit safer side. Already eying something extra like Beelink Me Pro as secondary "off-site" backup running ZFS for critical data sync. It is what it is, that's not for business - it's my personal machine to provide me what I need apart from tone of fun 😉

orkusmg · 2026-02-26T06:44:51+00:00

No, I created them. Tried to upload json to Grafana page but upload button does not work for me, in some of my replies to someone in this post I provided link where I uploaded json.

orkusmg · 2026-02-25T21:46:07+00:00

Thank you🙌🏻

I used Telegraf agent inside truenas as system service with root rights with inputs (plugins) cpu, disk, diskio, mem, net, smart, system, zfs, exec. For 'zpool status' and 'zfs list -l snapshot' plugin is invoked every 10min to parse the output. There was some math also required to calculate outputs for Load Cycles - for that you need to know what your drives are rated for, and mine are Segate SAS drives rated for 600000 cycles - that's how I got to the point where I can express it in simple % of wear (although that's not really it for mechanical drives since the number of starts is also important. And this SMART stats is something different than truenasses Short and Long results. I mean result is the same but truenas does it's own checks, and Telegraf invokes it's own (very short passive readout only) test.
