Yes. The 3900X and 3950X both have 2 CCDs. In fact, you can pretty much consider the 3900X / 3950X to be the (improved) successors of the Threadripper 2920X / 2950X. The key improvement is having an IO die so you don't have to worry about NUMA node optimisation.

There is a ZFS plugin. I think Wendell (L1Tech) even installed Unraid with ZFS for Steve (GamerNexus).

It depends on the size of the write and how much of it is sequential (vs random). For highly sequential writes, my (old) 8TB Seagate Archive behaves just like typical 5400rpm drives e.g. with 7+TB filled can easily take 100GB dump in 1 go at 100+MB/s. (note, the SA is very fast early, comparable to WD Black, but slow down to WD Red 5400rpm level towards the end, hence, 100+MB/s) For highly random writes, it gets down to less than 30MB/s after about 30GB or so i.e. way slower than a typical 5400rpm drive after the CMR "cache" fills up. One thing you have to pay attention to with SMR drives (in my own experience, the Seagate Archive) is that it is not designed for heavy random write (which is NOT typical Unraid usage). I managed to kill a Seagate Archive by writing so much random data to it that (I think) the CMR cache died. It was during warranty so I got a replacement without any fuss.

How much does it cost you to run an offsite server? You might want to consider a Cloud solution instead, especially if its main purpose is backup storage. It is much easier to configure the Cloud than working on exposing an Unraid server SAFELY to the Internet for you to backup remotely (and assuming you have an ISP that is port-forwarding-friendly, which cannot be assumed).. For the onsite server, it highly depends on what exactly you are doing. For example, it's not that difficult to set up a 10GbE network and connect your NAS to your workstation as storage. However, it is still over-the-network access i.e. you will have to deal with network latency, which is not insignificant. This is particularly true with photo editing due to the relatively smaller file sizes. It might be simpler and faster to just connect your storage directly to your workstation and set up your NAS as an onsite backup of your workstation.

Yeah I was about to suggest you use an alternative VNC client. I have seen in the past some clients work and some don't depending on how the gazillion local variables are set up. Even within browser, adblocks, proxies etc. can mess it up too.

Well then you need to consider if you actually need the storage feature of Unraid. If you do then you can dual-boot and boot into whichever one that you need at that time. Take care not to format your xfs-formatted drives because Windows like to nag about that. If you don't then you might as well boot into Windows only. One thing that you may have not considered: do you want to isolate your Windows machine (VM) from your storage e.g. in case of cryptovirus infestation? That was actually one of the main reasons I run a Windows VM under Unraid (instead of, for example, running a Linux VM from within Windows). Let's say I'm somehow infected with a crypto-virus, I can recover extremely quickly by simply killing off my infected VM and recopy my data from my backup (saved on the array) to my new VM (NVMe drives). It would take extreme hacking skill for the virus to spread from my Windows VM onto my Unraid array backup (it's not even exposed to the network).

Main -> Flash -> scroll down to syslinux section. While you are at it, Tools -> Diagnostics -> attach zip file.

Let's flip the question over: is there anything in Unraid that you can't do in Windows barebone? If there is, you really don't have a choice but to use Windows as a VM. If there isn't then you should stick to Windows barebone for simplicity and best performance.

Clarification please: you "suddenly had 2 empty shares" i.e. You had 2 EXISTING shares that had data in the past but now suddenly had nothing (i.e. you know there was actual data loss) You had 2 BRAND NEW / unfamiliar shares that were empty (i.e. you don't know if there was any data loss) (1) or (2)? (2) could simply be misconfigured dockers creating spurious folders.

Changing IOMMU is done in the BIOS. Unraid doesn't have access to your mobo BIOS to change it. If you are 100% sure it is on in your BIOS (Enable / On is different from "Auto". VT-d is different from VT-x) then check your syslinux to see if you might have disabled it in the past manually.

Sort of yes and no. If you pass-through the entire NVMe to Windows during install (either via PCIe method or ata-id method), then you can use the Windows installer to divide your NVMe into multiple partitions (and then format them). And then shutdown the VM, edit the VM template and just passthrough one of the partitions that you created (using ata-id method). If you look at Unassigned Devices, you will be able to tell there are multiple partitions and you will be able to mount the non-Windows for other uses and the Windows one for the VM. The drawback of this method is that Windows won't let you format the non-Windows partition in xfs format, which works better with Unraid and Unassigned Devices. Btw, you should use FAT32 for the non-Windows partition, and not NTFS. The above is kinda more user-friendly way to do it albeit rather long-winded. You can do the same thing using the Unraid console (either directly or via SSH). In your case though, you probably might want to use vdisk instead. The overhead using ata-id method or pass-through is actually only slightly less than vdisk (particularly raw vdisk) since you still have to go through virtio / scsi. In my own testing, only about 1% or so i.e. not perceivable in real life. If speed is important, PCIe method is the only way to go but of course the drive will be used exclusively by the VM.

libvirt should be on cache. Putting it anywhere else just complicates the matter. You can create multiple partitions on the same drive using command lines. Then just pass through a specific partition to Windows using the ata-id method. Probably no perceivable benefit if cache is SSD (unless you put extremely high load on the SSD). NVMe itself only matters with the right (heavy) workload.

Easiest solution: disable it after a fresh reboot.

From Unraid should be fine because it's read access. To Unraid doesn't work, potentially because of write access. Since it's a fresh Windows install, are you sure you provided the right user access when connecting to Unraid SMB? Maybe make the share public and see if you can write to it or not.

How do you connect to the VM VNC? Web interface? Local client?

MSI_util is THE fix for GPU HDMI audio issues. There is no point considering any other faults and fixes until you apply that.

I would say normal. My Intel NIC can get to 60+ under load and it's gigabit.

You should go back to page 1 and look for bastl's post with the Skylake emulation and use that. The reason it didn't work for the previous poster was because his CPU is FX 8320 which came out before Skylake (so it can't emulate Skylake hence unsupported CPU). Threadripper works fine with Skylake emulation. Generally, as long as your host CPU has AES NI + your emulating CPU also has AES NI + you don't disable it then it should have it.

These were the problems: Couldn't reliably save config. When config could be saved, it didn't retain beyond 1-2 boot cycles. Exit without saving = can't boot up at all (need to clear CMOS for it to boot back up). Saving profile crashed the BIOS itself (blank screen). Patch note said "PCIe bifurcation" as additional feature, which is misleading. It really just changes the wording of the BIOS setting for PCIe slots. This feature was already available for a while e.g. F12e, just under different name. I think Gigabyte only keeps the latest of each version number so the 12e probably is no longer available. These problems also could very well be my sample's idiosyncracies. If you guys have problems with 12i, just ask. I have 12e saved down (original Gigabyte version). Last but not least: if you need ACS Override, turn it on (and ignore all the security chatter). Only James Bond worries about being hacked through ACS Override on a home server.

The GTX 950 doesn't support NVENC so you won't be able to use for (Plex) transcoding.

It depends on your budget. You can make an extremely power efficient rig (relatively) by replacing all the HDD with SSD, use 80+ Titanium PSU etc. In terms of running cost, an extra 100W (that's overclocked idling sort of draw) is probably about an extra $10/month or so - if you can't afford that then you might want to reduce your PC budget. Otherwise, just forget it and stick to what actually fits your needs. Current gen CPUs, GPUS, and HDDs are actually (relatively) very power efficient already. It is generally more detrimental to your power efficiency if you overclock (i.e. if you actually do something on purpose that reduces the efficiency). Promoting a clean source of energy is better for the Earth than trying to shave 30W off your usage.

I believe the SM controller patch was already included in 6.7 (so should still be in 6.8). The Intel controller I haven't seen a patch.

Do you also happen to pass your 650 Ti to a VM (and/or vfio stub it in the syslinux)? Then it won't show up on Unraid Nvidia. The 650 Ti doesn't support NVENC so it would be rather pointless to run Unraid Nvidia with it.

As always: Tools -> Diagnostics -> attach zip file to your next post.

I just found out recently that the Asus ROG Crosshair VIII Hero has 8 SATA ports but only 2 M.2. So if SATA ports are important for you then perhaps consider that. I still think Gigabyte is better for the reasons I have said but I understand why having 8 SATA ports are important for some. The 3950X can handle 2 gaming VM's. It has the same number cores (16) as Threadripper 1950X / 2950X. The model numbering does suggest the 3950X to be the successor of the Threadripper 2950X. Whatever 2TB SSD you get, don't get Intel (660p and 760p). Intel has the anti-consumer practice of locking up the entire SSD in read-only mode after all the reserve has been used, under the pretext of data loss protection.Both 660p and 760p models have also been reported on here to be not happy with PCIe pass through. And the 660p is QLC (NVMe QLC is like driving a Ferrari off road - avoid it. There's a use case for QLC, just not as an NVMe SSD). No, Unraid doesn't have dedup.
