I have observed similar behavior across several servers for a long time now and figured it was just a characteristic of the OS. It does this for me even as low as 35MB/s, but at the same time, I can also transfer 400MB/s, so it doesn't seem to be a bottleneck (even though I also see io wait)

14 on the main server because that’s how many I need to keep things organized 1 on the backup server because that’s all it needs O on the vm server because it’s only purpose is hosting vm’s

I run a virtualized instance of an enterprise-grade firewall on my box. This keeps viruses and other nasties from penetrating my network and infecting my hardware. But at the same time, my friends with benefits can still gain access to my 9TB worth of Hard Disks for their pleasure. It may be hard to swallow, but taking the time to carefully setup your sever will pay dividends later with all that data going in and out, and in, and out.

you could start by updating your bios

Are you thinking about single or dual E5-2667v2? A single cpu is essentially double the passmark score of your current config. You'll have to consider how you would provision them, either per core assignments, or over provisioning them on top of each other. Maybe a dual socket board using one socket only to start and see how that goes? I never had much cpu usage with next cloud, but duplicate always seemed to eat more cpu than I thought it was worth, especially when using encryption. Pi-hole is pretty light on cpu needs.

how many game servers are you running (like total instances)? for comparison, with a couple users, my single mineos consumes about 20-30% of one core depending on activity levels. What utilization are you seeing on your current setup when running game servers? also, when using plex and transcoding with a low end Nvidia gpu, it adds another 15-20% to a single core (vs all of any cores assigned when CPU transcoding), just to note.

step 1: backup your .img os step 2: make a new vm but have the disk location point to your old image instead of creating a new one step 3: boot with vnc only and verify .img os works step 4: shut down vm, reassign GPU step 5: boot vm step 6: report findings

what you way you want conflicts with what you say you need. if your current level of cpu handles all the gaming servers, and you added 39% more power with the outlined proc above, you'd have WAY more than you need already. And justifying more cpu power for plex is negated by using a more efficient GPU for transcoding. On my primary server, using a E3-1220 v5 (passmark 7768) it runs a vm with firewall, NAS storage, could berry (2 instances) for encrypted backup, plex with GPU transcoding, mine0s hosting few worlds, next cloud/mariadb/duckdns/letsencrypt, zero tier, wireguard, 10GB networking pushing and pulling over 500MB/s, and a few other things. And it never struggles. I use to have a quad socket 580G7 with 80 threads, but this newer one kills it in terms of efficiency and actually runs smoother. Point being, if you're dead set on having "all the cores" then go for it. But I don't think you really need them. And on the subject of Ram, yeah, max that out IF you have a need for it. Otherwise, its again a waste. I'm not saying buy the workstation I outlined, I'm saying understand the need, and where you're going to grow in the next few years. Because right now, your use case and wish list don't line up.

Don't limit yourself at 4 slots. Make a DIY JBOD box. get an sas expander with a x4 port out the back. Get an hba and connect it to the expander (or you can also get the 20 dollar cards that convert it to the right cable), then cable that to the enclosure with another x4 input. then either use breakout cables to connect directly to the drives. I've used an md1000 before for quite a while, but it was loud and power hungry. after I build my jbod encloser, its way quieter, uses less electricity.

Change the install path to something with a different folder name, like put a 1 on the end or something

here are a few things to help you:

It’s almost as easy as googling “unRaid maxinabox” and following the video instructions

maybe just have new shows that people are craving added to a ssd cache raid 10 pool or nvme drive for a time period before moving them to spinners.

page 5 didn't show up for me at the time of my posting (most likely a stale window.) but either way thats news to me, except in a few cases when the device/address that triggers the RMRR error isn't passed through (like omitting sound from a gpu). seems you've got this all figured out then and should be able to fix his issue. carry on and I look forward to learning something.

I was worried about that too, but after a few years its not a big deal. plus I'm using otherwise wasted cpu cycles, can upgrade or downgrade ram in a flash. I don't have to worry about how much a vpn will tax the processor, or any other performance wall that standard consumer appliances can face without spending hundreds of dollars. the flexibility is also nice to have, not being locked into "this is it, this is all it will ever be." AND the ability to have a variety of different firewall software choices with typically more robust support. but, to each his own. simplicity can also be worth the price

so.... why not virtualize your firewall on your server via pfsense or sophos/etc...? thats 20-40 dollars for a dual or quad port Nic, then spend 60-80 on a wifi point.

I never said anything about your poor grammar. I said So at this point, I'll follow your request and I'll ask you questions to better understand what I need to help you: 1. Do you want this fixed? 2. Are you willing to go back and add punctuation to your post so it's not a gigantic run on, semi coherent sentence? and 3. Can you drop your attitude? You may attract more flies with manure than honey, but you end up smelling like it in the process. You should read the top of the thread as it pertains to RMRR issues and proliants. It's not a red herring, it's a legitimate bios issue that prevents working hardware passthrough.

a lack of punctuation does not help your situation either.

about 2 months ago I bought a z440 from this place: https://www.ebay.com/itm/HP-Z440-Workstation-M1H93UC-ABA-Desktop-PC-Xeon-E5-1650-V3-3-5GHz-32GB-SEE-NOTES/372888072889?hash=item56d1dc72b9:g:wy0AAOSwrxpeJcMc:sc:FedExHomeDelivery!30127!US!-1 I actually lowballed and they countered, we ended up around 250 12 cores with ok clock speed (passmark is 13k vs your current 8k setup.) currently runs 2 vms at the same time (one of them games on a rx 590 hitting over 100fps on fortnite) and also serves as a backup destination for network time machine and vpn service via wireguard. but not a ton of space for spinning disk. You'd have to look into getting an enclosure for the top 5.25 cd space. not rack mount but mountable. with the extra money you could buy more ram if you wanted plus a cheap gtx 710 for Nvidia transcodes to offload the work from the cpu.

Jesus said “love thy neighbor as thyself.”

And an answer was provided. If they can’t operate a vpn, plex is the easiest. If you are unwilling to pay for a gpu, and they are unwilling to pay for a gpu, and you don’t want your cpu to transcode, then you’re SOL essentially. Unless you want to transcode your entire library to a native codec/bitrate that their bandwidth accommodates and works for their smart TVs..... and every movie after for them.

then tell them they don't get access. noting worth anything is free in this life.

Plex is easiest. and tell them to buy you an nvidia card, then use hardware transcode with that. You’ll barely have any cpu usage transcoding then (just audio only)
