I would love to know what firmware his card is running and what settings he used (in esxi and in his card bios) and what build he is using.
Mine is running in IT mode FW: 11.00.00.00 / BIOS: 7.21.00.00 / 22-AUG-11 (LSI P11), but I'll flash it to whatever mode I need to if it'll work via passthrough.
I got bored and setup 2x3tb last night via RDM, but I'd love to do it via VT-d.
