  1. The only difference is the firmware You'll find some useful informations about cross flashing this controller here: http://www.servethehome.com/ibm-m1015-part-1-started-lsi-92208i/
  2. This is the reason I stick to Intel based platform. There is not enough information about IOMMU usage in consumer motherboard.
  3. Hi I had similar experience this summer. My setup under ESX 4 passed through the adaptec 1430SA flawlessly to the Unraid guest It worked great until I upgraded my host to Esxi 5U1. Since then I had problems with Unraid and was not able to make it work right under ESXi Finally I build a new physical box for Unraid. I'll give it a try with the new ESXi 5.1 and probably a new controller.
  4. As far as I know the CPU and the motherboad have to support VT-d in order to passthrough PCI/PCIe devices This document may help you http://wiki.xensource.com/xenwiki/VTdHowTo
  5. Another advantage of passing through the controller is that it left the disks outside the virtualization layer. If something happens to your controller or your mainboard, just plug the disk in another computer and you'll find your data again... By the way you can find cheap mainboard with VT-d support like the Asus pq5-vm-do
  6. Do you think that it is safe to re-enable write caching after the firmware upgrade?
  7. I dit some tests this week-end with my p5q-vm do. Using a PCI controller (Promise 300 TX4) passed through the UnRaid VM, I got the temperatures and the drives spin down. Parity Sync run at 30~36MB/s. So its fully fonctionnal but a bit slow... Unfortunately I was not yet able to use a controller on the PCIe x16 slot. I tried 2 controller (Promise TX8660 and an adaptec, but I do not remeber the model). With both controller I can't see any drive in the BIOS...
  8. I'll get an Asus P5Q-VM DO tomorrow. This board should be able to passthrough a controller card to my UnRaid VM. I'll try 2 Promise card, one PCI et one PCIe I'll keep you informed of the results
  9. I did some research on the passthrough. It seems that you need a CPU and a motherboard witch Intel VT-d support or AMD IOMMU. nojstevens, can you tell me which motherboard or cpu you're using? Thanks and best regards
  10. Hello nojstevens. Which Supermicro card did you use? the PCI-X or the PCIe 4x? I'm currently testing with RDM, but my ESX host has already crashed twice during the data moving... So I'm less confident now and I'm beginning to look around the pci passthrough thing.
  11. Hi all, I finished to setup my UnRaid server on a ESX server yesterday. I'm currently copying my 4TB from my old box to the new virtual one. I'm missing the temperature readings, but I still did not have the time to check wether the drves get actually spun down. I'll have to check after the copy is done. drealit, you'll find here http://ultimatewhitebox.com/iocontroller a list of ESXi compatible storage controller.
  12. Hi You can use RDM on sata drives you'll find the way to do this here http://www.vm-help.com/esx40i/SATA_RDMs.php
