  1. fwiw, I've done this before to troubleshoot an issue and it didn't seem to have any impact... but again, I would prefer not to have it there primarily because of the slower transfer rates.
  2. Unless someone knows the answer already, I need to figure out what will provide the fastest transfer rates for a USB3.0 HDD to copy (backup) files to it. a) mounting it as a share b) mounting it as a USB device in the VM setup c) mounting a USB3.0 controller with the HDD attached (gridrunner's how-to video) and his device setting suggestion (assuming the VM will remain stable) Right now, I'm trying to recover a partition on a failed drive (unrelated to unRAID) using a VM but I can't afford to have unRAID crash during the process.
  3. Thanks for taking the to to offer your opinion, darianf. Here are my thoughts: 1) Good to know; as much as I like this board, I wish the PCIe architecture was more robust. 2) I haven't seen any issues that I could confirm are related to this configuration. I don't want to move the hard drive controller to the x4 slot mainly because the unRAID transfer speeds are slow enough already (around 45MB/s more or less read/write) and also, because it will butt up against the PSU. 3) Regarding the speed of the controller, I found this info online: + https://www.supermicro.com/products/accessories/addon/aoc-sas2lp-mv8.cfm - States the Bus Type is PCI-E x8 Gen 2*; Up to 6.0 Gigabits/sec per port + https://origin-www.marvell.com/storage/system-solutions/assets/Marvell-88SE9485-9445-Product-Brief.pdf - "The Marvell SAS 6Gb/s host controllers support four or eight SAS/SATA ports, including native 6Gb/s SATA interface support, and as many as eight lanes of PCIe 2.0* connectivity..." * I have no idea what PCIe 2.0 transfer rates are. I thought one could only achieve 6/Gb/s with PCIe 3.0... I don't know! 4) Good to know, I have a GeForce 8800GT w/512mb (if memory serves). Do you think that would work? Other thoughts: Ultimately, I'd like to do a passthrough using the elCheap-O card for the bootup sequence and pass the other one through to a VM. Unfortunately, I would have to sacrifice what performance the x8 slot is providing to the Supermicro HDD controller and move it to the x4 slot to make this work; hence my love/hate relationship with the MB. Thanks again for your thoughts.
  4. Here is a screenshot of your motherboard layout for the PCI\PCI-E - not that its much help, I just like screenshots Yeah, ASUS didn't spare any expense in the printed manual either! lol For fun, here's my physical configuration: Slot 1; PCIe 2.0x1_1 - Inatek 7-Port USB 3.0 PCI-E Card KTU3FR-5O2U (as used by gridrunner but this is the US version) Slot 2; PCIe 3.0x16_1 - el Cheap-O GeForce 7300 LE gfx card (this slot is shared w/Slot 5... if I understand the manual correctly, it shares at x8 grrrr ) Slot 3; PCIe 2.0x1_2 - SiL 3132 eSATA card (Sonnet?) Slot 4; PCI Slot 1 - EMPTY Slot 5; PCIe 3.0x16_2 - SuperMicro AOC-SAS2LP-MV8 SATA Controller Card 8 lane (Shared w/Slot 1) Slot 6; PCI Slot 2 - EMPTY Slot 7; PCIe2.0x16 - EMPTY (While it fits x16 cards, I suspect it only operates at x4; can anyone confirm?) Not sure what (if anything) can be learned from my current config. When I first decided to convert my windows box to unRAID last year, it was disappointing to discover that this board shares its x16 slots and uses the older and slower PCIe specs. Oh the things I've learned along the way for the next build. Anyways, ENJOY!!
  5. Thank you for your suggestion, Darkun1. Unfortunately, my bios doesn't seem to offer such a setting. fwiw, I also tried passing through the on-board Renesus USB 3.0 controller with mixed results: it seemed to work ok with Win10; however the Win7 drivers are unstable and would often times crash or prevent the VM from loading. I would love to find a solution since the only way to access the attached external drives are as network share, which is extremely slow. Anyways, again, thanks for your suggestion. With the Inatek USB 3.0 if you can try another PCIe slot for it. Also, check nothing else is in its iommu group. Maybe worth a shot, you could try using pci-stub.ids= instead of vfio-pci.ids= in the syslinux.config. Also with the onboard USB controllers and the windows 7 problem you could try in bios changing EHCI Hand-off from [Disabled] to [Enabled] Cool! I will give those suggestions a shot when I have some time to troubleshoot. Yes: the card is in its own iommu group and it can be reset; your online videos are a tremendous help! In other news, I have an SiI 3132 eSATA card and a single Nvidia gpu that at some point I would like to be able to passthrough to a vm. Would you recommend postponing trying either or both of those until the USB issue is sorted? Many Thanks!!

  7. gridrunner, THANK YOU SO MUCH for the making the amazing and video!! I found it incredibly easy to passthrough my Inatek USB 3.0 controller I just purchased a few days ago. I'm hoping you (or anyone for that matter) can offer some suggestion to an issue I'm now facing. Since adding/passing the USB card, the unRAID system intermittently freezes after awhile when I run my VM which is using the controller. (today it froze after ~18 hours of uptime) The only way out is to hard reset the unRAID tower. Thank you so much for any thoughts/advice you have to offer.
  8. Here's a few more I did; inspired by @gridrunner, who has a great unRAID youtube channel, and @perhansen for the background on a couple of these. ENJOY!!
  9. Can you make it without the XEON logo in the middle? Looks awesome. Cheers. Here ya go mate... hope I didn't overstep a boundary with @perhansen by taking the initiative to do this.
