[OmniOS-discuss] anyone doing DirectPath I/O?

[Joseph Boren]

Thanks guys, that's very helpful.

Tim that sounds very close to the use-case i had in my head.  I've run into
a couple of situations where a VM sitting on ESXi on particular hardware
was much more performant than the exact same system, bare-metal on the
exact same hardware.  Once I actually P2V'd a server to a temp location,
loaded ESXi on the physical server, migrated the P2V'd guest back and it
was crazy how much faster and stabler it was.  So now days I tend to want
to run ESXi on the bare-metal, but I didn't have any experience with
DirectPath, and it looked perfect for this situation.

Thanks again gentlemen, much appreciated.

Best regards,
