# On linux operating systems the kernel parameter nvme_core.io_timeout controls
# how long the operating system waits before it considers an IO request to be
# failed. It should be set to 4294967295 or the maximum value that the
# operating system allows.

# On linux operating systems the IO scheduler controls how the operating
