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 what
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
