Hi, I did some testing today on the Z820 workstation. I checked more and the processors are two E2680v2 20core 40threads, 64GB ddr3. I installed the unRAID trial, two 80GB 3.5 disks at 7200rpm, GeForce 1080, and the power consumption was 135-150watts Then I started the following tests: -installed cpu governor plugin and set to power save: no change in watts consumption -bios: tests done in order and one at a time, enabled s5 power save status, disabled turbo mode, disabled hyper treading, enabled only one processor (so one out of two), enabled hp cecp (China Energy Conservation Program), lowered fan speed: no noticeable improvement in watts consumption -removed video card to try headless boot: workstation won't start (rightly so) -removed gtx 1080 and mounted a very old gt120: consumption dropped about 10watts. Unfortunately 135-150watts/hours in idle are very high (126-140watts with the gt120), but this workstation also has many advantages, such as the ability to mount sas disks, many pci-e slots to mount 3 gpus and a 10Gbps card for example. I have also noticed that using unRAID on this system is very fast, even in installations and in reading and saving parameters. Small OT, on Friday I repaired a power supply to a customer and in return he lent/gifted me this build: i7 4820k, Asus p9x79ws (motherboard that I love). Could I use this for unRAID as a good compromise between performance and power consumption, combined with a good plus gold power supply?

Thanks, great suggestion to use the trial to test the workstation and real consumption (I should also have some old 80GB sata 3.5 disks somewhere). The workstation has no add-on cards, it is an HP Z820 which has both the lsi sas sata controller and the intel controller integrated into the motherboard. So I think I could even mount sas disks. It also currently mounts a GeForce 1080 video card, but I don't think I would use that except in a vm. Thanks also for the suggestion for a new build, I would opt for an i3 12100 with integrated gpu, ddr4 and low power consumption I will definitely do some testing this weekend.

Thank you for your answers. I took the time to do some tests: I created two shared folders on unraid, one on the wd blue drive and one on the wd black drive. I then copied a 13GB folder of data (photos and videos) first to one share, then deleted it, and then did the same on the other. Results (copy on Gigabit lan from computer with nvme ssd): WD BLUE: write time 3m53sec, cpu usage 40-100%, lan max speed 109MB/s WD BLACK: write time 2m52sec, cpu usage 40-100%, lan max speed 109MB/s Ram usage: 22% of 8GB ddr4 VM: no Docker: no No lan traffic, only one pc and the microserver unraid I really think the problem is the cpu, disks seems ok. Now I am facing a doubt: I have a dual xeon 2680V3 10core workstation, 20threads x 2, so 40threads, 64GB ram. I would like to use it, so that I can configure some VMs and dockers as well, but I am very concerned about the power consumption, which is around 200watts when it is on bios and 20w when it is off (unbelievable but true, measured via ups powerstation). Is there any way to lower the consumption of the dual xeon by a lot, or should I sell both the hp microserver and the dual xeon workstation and buy new hardware, such as a Ryzen 5600G?

Hi, I've two UNRAID server: -one with Intel Pentium G3258 and 18 disks that works very well -other is a hpe proliant microserver gen10 with cpu amd opteron x3216 apu (only two threads as G3258) but 8Gb ddr4. It has two disks actually, one WD Caviar black 6TB (cmr) and second WD Blue 2TB (old model CMR), no parity for now. I use this pc only for storage, no plugin, vm or docker. Unraid versione 6.11. The problem is that the cpu go to 75%-100% usage only for write or read lots of file on Gigabit lan. Yesterday I had to reboot cause WD blue give read errors (cpu at 100%) and then the disk didn't show me anything (no files, no temp, no possibility to do a smart test)...luckly after a reboot everythig restart to work. Disks are more or less 10000 hours, no smart errors. My answer is: is the problem the cpu or something else? I want to add 2 more disks, but if the problem is the (slow) cpu i will switch to a pc with better hardware. I don't want to have problem to this storage cause i will use in production and I'm afraid that adding a parity disk and cache disk the situation will become worse.... Thanks to those who can help me
