Ich habe mehrere crossflashed und debranded SAS2308 und SAS3008 auf der letzten IT-Firmware (den BIOS-part habe ich weggelassen, die sollen nur HBA spielen), laut Datenblatt sollen beide SR-IOV mit jeweils 16 VFs können.

Nun würde ich gerne von einer Karte die beiden Ports jeweils auf zwei VMs verteilen. Aktuell habe ich pro VM einen ganzen Controller durchgereicht, somit mehr Stromverbrauch und einen PCI-e Slot belegt, den man anders bestücken könnte. :confused:

Mit NICs ist SR-IOV ja kein Problem, aber hat das jemand von euch mal mit SAS-Controllern hinbekommen?
