  1. For this system, can you tell me exactly how everything is set up? Card make & model, where the cables plug into, backplanes, etc.
  2. I've got this device to connect to a VM using a standard USB passthrough and it added perfect sound: https://www.amazon.com/gp/product/B06XNJLHXS/
  3. This looks like it's going to be something I can't easily add support for without access to the card. So I ordered an SAS 9207-8i - same as yours but with internal ports. It'll be delivered tomorrow, I'll be able to plug it into my backup server sometime later this week.
  4. Check out the spaceinvaderone videos on installing lstopo which will give you a visual representation of your numa nodes, the CPU's & PCIe slots tied to them. This will help you pick your CPU assignments.
  5. Redid the 2 numa node test after properly configuring the XML so Windows 10 detected two numa nodes. Performance was the same <cpu mode='host-passthrough' check='none'> <topology sockets='2' cores='8' threads='2'/> <numa> <cell id='0' cpus='0-7' memory='4194304' unit='KiB'/> <cell id='1' cpus='8-15' memory='4194304' unit='KiB'/> </numa> </cpu>
  6. Adding nohz_full & rcu_nocbs yielded no difference within a margin of error with a 0.23% decrease over the 2/8/2 topology settings.
  7. I did some tests on my Threadripper 2990WX 32 core chip with the different topology settings and did 10 passes with PerformanceTest 9.0 and averaged the results. OS was Windows 10. <topology sockets='1' cores='32' threads='1'/> The default setting with the cores pinned to span two full numa nodes gave me an average score of 17910.3 <topology sockets='1' cores='16' threads='2'/> Setting it to match the 16 core HT scored 17867.8, 0.24% slower <topology sockets='2' cores='8' threads='2'/> Making it match the numa node with 8 HT cores scored 17955.5, 0.25% faster
  8. Please execute the following command on the server, does it return the Serial Number? smartctl -i /dev/twa1
  9. Can you create a debug file for me? Launch the app again and replace the URL after the port with the following when you get this error: http://[IP]:18888/isolated/CreateDebugInfo.cfm Select "Create debug file with controller info" This will create a zip file on your appdata share that contains log files from the app and a copy of the sys file tree of devices and email it to hddb@strangejourney.net or upload to a file share and send the link to it.
  10. I have multiple Win 10 VM's. I started "Cam 1" and then immediately started "Cam 2". "Cam 1" displays it is paused and "Cam 2" reports it has been started (green arrow) Resuming "Cam 1" reports that the domain is already running. Simply waiting and taking no action reports both VM's as running. vm1-diagnostics-20190904-0723.zip
  11. I added code to invalidate a test result if a drive gives a 10% or greater improvement in speeds over it's single-drive speed.
  12. It's weird that you're seeing such a variance. It's the same command given to each drive - read balls-to-the-wall starting from the start of the drive and 15 seconds later a kill command is sent - regardless if it's running on it's own or all at once. Did you click off of it or otherwise leave the benchmarking page at any point prior? I added code to stop reads if such an abort takes place. If you have the "Dynamix System Statistics" plugin installed, check to see if there's constant drive activity such as one of those tasks are running wild. If stopping & starting the DiskSpeed docker clears it up, then I have more work to do on that front.
  13. Perform a benchmark on it every week or so to see if it returns an identical test. If it does return an identical test over the span of a month, it may just be how that drive is.
  14. @wgstarks - can you also include a screen shot of your System Bus Tree?
  15. Can you share the graphs of the controller benchmarks? Drive 9 was found to have a steady read speed over a large portion of the drive when it should be declining for a spinner, this indicates that the drive can send data faster than the controller it's attached to can handle. You also have a drive that has a wave to it. Can you tell me what make/model drive that is? Waves can be a sign of degraded areas. At a minimum, perform a benchmark on it every month or less to see if it holds steady - if it does, it may be how that drive was designed to operate. I'm working on updating the Hard Drive Database web site so it displays the latest benchmark from everyone who has the same drive (instead of averaging all tests which can cause big spikes) to see if that's just how that drive operates.
