Optimizing Server Performance

Optimizing Server Performance

You can modify the SAS DM device scheduling policy to optimize the server performance.

  1. Run the cd /sys/block/dm-0/queue/ command to go to the queue directory.

    The DM devices dm-0 and dm-1 correspond to the LUNs created based on the SAS SSDs and must be changed based on the actual situation.
    HW00001: #cd /sys/block/dm-0/queue/

  2. Run the echo noop > scheduler command to modify the DM device scheduling policy.

    HW00001:/sys/block/dm-0/queue # echo noop > scheduler
    HW00001:/sys/block/dm-1/queue # echo noop > scheduler

  3. Add the following content to the /etc/rc.d/boot.local file:

    for sd in `ls -lha /dev/disk/by-id/scsi-hana* | awk -F '/' '{print $NF}'`; do echo noop > /sys/block/$sd/queue/scheduler; done
