looks like an Private server, if i where you, i would use Unraid with that, we have an pretty similar system and the easy to use Docker system and very well working virtualisation on Unraid would make much more performance than you let on the table now. Heck i got sriov working om my IGPU and 28gbit dual Mellanox NIC and ZFS is working fine now.
I can say with first hand experiance while working on flight simulators, our buildings had garbage power feeds coming in and we saw a lot of outages. When the power went out we scramed to get all the severs down before the ups dropped out…. if it was a long outage we could almost guarentee a dead drive in the building when we powered back up. If the ups didnt hold until you got the stack shut down you knew what rack was getting a new drive and battery tray! I replace my drives critical storage drives ever 5 years and toss the old good ones in my plex box since it always needs more storage.
One option could have been to use only 1 cpu off your dual cpu server. That can nicely shave off some watts.
Is the base file system zfs, ecc would have been nice?
Would have loved to see you build a new server and transfer VM’s over with no / minimal loss of uptime.
If you’re limited to hardware you have, fair enough, but what I don’t see is a lot of homelabbers doing it the enterprise way when they swap hardware.
I'm using a 4U Rosewill L4500U case with a Thermalright cooler because I'm cheap. The Phantom Spirit 120. It's <158mm, cheap and reviews suggest it performs better than the U12A while being about $80 less. For other cheap viewers, consider the option.
i cant even afford newer hardware for my personal home server currently but i wish i could afford to bht hardware sometimes has hiccups but it still works
4:48 hold up. Are you sure you mean SR-IOV? this is available? why did no one tell me?
Can you share the 3d model of the fan attachment you used?
Windows Task Manager tends to report the highest clock of all the cores, which often changes and likely will never match HWINFO perfectly. If anyone knows more or has a correction, let me know.
Also I'm glad I just found this channel. Very cool ^^
Curious what your asset management situation is like for tracking things like equipment, sata cables, and squirrels.
ElectronicWizardly did a video about Proxmox on Intel. According to him, Proxmox cannot properly balance workload across P- & E-cores. Hopefully, Proxmox will make it happen eventually. Until then, hybrid CPUs are not the best choice for VM server.
My linux workstation has 6000mt/s at 98gb (7950x, Trident Z), I'm not sure if 128 is totally different, but I'm sort of surprised that I just hit expo and after I verified it, never had to look at it again. I feel pretty lucky tbh, and I wish it would work better than it does.
I'm running a 7900x with 128gb at 6000mhz. Passed in all mem tests.
Thank you.
The issue with spinning down drives is the strain on the motor at startup. Now that won't kill a drive quickly unless it's being spun up really frequently, but it is an added opportunity for it to fail. And with a decently sized array, you also have to consider the power surge of all that rust spinning up, something that won't of itself kill the power supply, but again, it's another opportunity for things to fail. I feel safer, especially as I use refurb drives, to set power saving to max, without spindown.
For the AMD parts in the description, you could've mentioned the non-X version of the 7900 since it doesn't suck too much power, yet performs really well.
Thanks for the video an appreciate the honesty on the build, so many people shy away because of a fan boy stuff, this video shown your like me i build a computer and select parts based on use case I have AMD and intel through out my network, I think AMD needs a better IO especially when boards come with so much stuff already, I did not know about the Virtualization issues with pass through though as i not come across this issue on my setups but its good to know, thanks bro.yeah the larger drives are crazy prices right now and it makes it harder to determine if larger cap with less drives is going to save on power and make its money back, i would wait a little then go for it as it would take X amount of time before you see the saving, but generally speaking you would save on power but depending how much you pay for the electricity will determine if its a saving or not. In Australia we pay 5 times the amount for electricity so it could save money at that point.
plus our government is on the save the world by increasing peoples usage on power driving up the price even more.
I'd be interested in cinibench results for the old server hardware
SR-IOV is such a cool tech that's so underrated. I recently got it working on an 4-port Intel Gbe card in a Lenovo 1-litre PC that's pulling router/firewall duty for me (firewall running in a VM under proxmox). I immediately saw a huge speed improvement over my previous Ubiquiti ER-X, even when it had HW-assisted NAT enabled.
Did you cut your "R" button in half too?
