Most NVMe devices only need 1 I/O queue pair to get their full performance,=
 but
that's ultimately up to the device. SPDK places no new requirements above w=
hat
the device requires.

SPDK does not use interrupts, so MSI-X is all disabled and doesn't matter.

SPDK will just automatically do the right thing for MDTS and optimal write =
size
and striping and all of that. You don't have to worry about it.

Thanks,
Ben
