Filesystem Configuration

For Dell PowerConnect W-AirWave 7.4, the NOOP File I/O scheduler provides the best random write performance. If you are running Airwave 7.2 or newer, Airwave should automatically manage this setting for you.

To check the currently assigned scheduler (if sda is not your device name, please replace with the correct device name):

# cat /sys/block/sda/queue/scheduler noop anticipatory deadline [cfq] (Sample Output)

To configure noop as your preferred scheduler:

# echo noop > /sys/block/sda/queue/scheduler

And confirm that your change has been applied:

# cat /sys/block/sda/queue/scheduler

[noop] anticipatory deadline cfq (Expected Output)
