I/O scheduler
When using SSD devices, it is recommended that you modify the devices' I/O scheduler.
Type the following on each server, for each SDS device:
echo noop > /sys/block/<device_name>/queue/scheduler
Example:
echo noop > /sys/block/sdb/queue/scheduler
NOTE: For most Linux distributions, NOOP is not the default. Different Linux versions have different default values. For RHEL7 and SLES 11/12, the default value is deadline, but for older versions, the default is CFQ.
