I currently use a M1015 controller w/HP SAS expander for my FreeNAS VM in ESXi 6.5.
I want to put in a hardware RAID1 controller in the ESXi host to hold the datastores.
I got an old Adaptec 3405 RAID controller to do this as it is compatible with ESXi 6.5, but I just found out it has one caveat: it only works if VT-d is turned off.
Since I'm passing through the M1015 controller to FreeNAS that is *NOT* an option.
I am thinking of getting another M1015 as it is relatively cheap, well-supported, and I already have lots of experience with one.
What I want to know is can 2x M1015 co-exist in a single computer if one is in IR mode and the other is in IT mode? I can of course choose which controller is passed through in ESXi, but what I can't figure out is what happens when you mix IR and IT modes.
Should I reflash the M1015 I have now to IR to match the new one? If I do that do the cards have separate configuration utility screens, the configuation utility control both cards simultaneously, or only 1 card can be configured?
