    Is none the correct Linux I/O scheduler to use?

    zperry

      We have got a few new Intel P3700 800GB NVMe Gen3 PCIe SSD cards. We put them into a few brand new servers and kickstarted them with CentOS 7. After installation, I was surprised to find that

       

      [root@sc2u0n0 ~]# cat /sys/block/nvme0n1/queue/scheduler

      none

       

      I couldn't find this scheduler option anywhere, definitely not from the official Linux doc on kernel.org.  Can anyone confirm that this is the correct setting?  Or if not, do I need to change it to say noop?

       

      Thanks,
