  1. Are there any power management features available? Possible methods of reducing power usage during GPU idle, etc?
  2. That cpu supports 24 pcie lanes if I recall, that means each graphics card will take 8 each, and the lsi card will use another 8 which means that you may not have enough to use the m.2, and definitely not both m.2 slots. The best thing to do is to download the manual for the motherboard and look into the details... Many boards disable a few sata ports if using a second m.2. A lack of pcie lanes is a major limitation of desktop hardware used as a server. Motherboards are often configured so that the 3rd 16x slot, and the second m.2 are tied to the chipset rather than the cpu, which can give you
  3. I think the H700 can be flashed to it mode... Look into it. That's not a bad server for the money. Especially considering the added storage options. I used to run my unraid on desktop consumer hardware and the upgrade to the server chassis has made it so much nicer. That being said, you could always try it on the hardware you have, and make your decisions from that experience as to whether or not it fulfills your needs adequately. Unraid is pretty portable, so setting it up with a couple of disks and tinkering then moving the USB and disks to the other machine and trying that out should be pr
  4. One thing to consider is that the Xeon cpu has many more pcie lanes, allowing for more flexibility down the road. You could add a HDD controller, and suddenly support many more drives, or you could add a pcie nvme adapter and slot in nvme drives if you really want the performance. My vote is for Xeon in almost any server scenario
  5. One thing to consider is that many usb drives come with mbr boot sector not uefi, and I've had a couple of generics that just didn't like the unraid usb creator at all, and a few others that I had to manually replace the mbr with uefi
  6. you can keep your data, unless you are changing the filesystem type, which you may want to do (btrfs raid1 is recommended). If you have another drive to offload the data to temporarily that would work. To switch from array to cache, you would need to create a new config (Tools > New Config) and simply assign the single disk as a cache drive instead of an array drive. Once you have the cache disk assigned, you can easily add the second drive to the cache pool after the fact, and convert it into a raid1 pool without any data loss. That would offer you the best redundancy. I have two cach
  7. If redundancy is your concern, and you only have one storage device, then you might want to just get a second identical m.2 and set them up as a btrfs raid1 cache pool and forego the array altogether. Probably get better performance than your current setup, and have redundancy.
  8. Unraid recognizes drives by uuid, so it will remember the disk order in the array regardless of any changes to the /dev/sdX assignments. You shouldn't have any problems as long as all the same drives are connected.
  9. Sandisk 32gb ultra fit usb 3.1 https://shop.westerndigital.com/en-ca/products/usb-flash-drives/sandisk-ultra-fit-usb-3-1#SDCZ430-032G-G46 Im sure it's not the greatest of all that is flash drive, but it's served me well thus far.
  10. The pcie4 nvme would just run at pcie 3.0 speeds, which means you aren't going to benefit from the gen4 device. It may run a smidge faster than a standard gen3 but I doubt it. I wouldn't pay for gen4 speeds when you're not going to benefit from it
  11. I use a USB 3.1 flash drive in a USB 3.1 port to boot from without issue. I think that there may be fewer issues with booting from USB 3 on newer hardware. Doesn't hurt to try, if you experience problems with it, then fall back to the USB 2.0?
  12. Just taking a look at your motherboard manual: on pages 6,7, and 16 it explains a bit more about your pcie options. It looks like the 4 lanes you have remaining can be used as a second m.2 drive (Read note on pg16 regarding type of m.2 connector!) OR the two 1x slots. I dont think the 1x slots will work if there's a second m.2 drive installed. It might be best to look into a PCIe 3.0 1x SATA controller that works properly in unraid, or getting to the bottom of why the one you have seems to be recognized in the bios, but not by unraid. I just noticed that this item
  13. I have an LSI 93111-8i flashed with IT firmware R20 with 12x 8TB WD drives attached to a Supermicro Backplane (BPN-SAS3-826EL1). There are two different models of these drives in use: (7x) WD80EZAZ as well as (5x) WD80EDAZ. When I look in the logs, I'm constantly getting errors like this, and it doesn't seem to be specific to either model of drive.

  14. I run a Supermicro X10DRU-i board with ddr3 in quad channel on a pair of e5-2690 v3, and it eats anything I can throw at it. Remember that ddr4 may run faster, but it's at a higher latency, so I don't think it will be a noticeable difference in your usage case. Unless you're running really memory intensive applications.... You'll really benefit the most when running quad channel You'll also have the added benefit of more pcie lanes on the Xeon,as well as ECC support
  15. Technically it's more than 'necessary', but hey, it'll be d*mn nice to have. Check out https://developer.nvidia.com/video-encode-and-decode-gpu-support-matrix-new . That says the Quadro P-2200 has everything you need for 4k transcode. Yes, if you're using the same drives, you should be able to simply boot the usb from another machine with the same drives connected, and it *should* boot fine. There might be some little tweak you need/want to make on the new system, but unraid is a pretty portable OS. Nvidia drivers and unraid have changed a bit recentl
