CPU Configuration

Ensure that Power Management is configured for Maximum Performance. By default, most vendors configure
BIOS to an eco-friendly setting.
Ensure that Memory Operating Mode is configured to Optimizer Mode, if available.

Disk Partitioning

Dell PowerConnect W-AirWave automatically partitions the disk subsystem upon installation. You can override
these values.

Filesystem Configuration

For Dell PowerConnect W-AirWave, 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 you change has been applied:
# cat /sys/block/sda/queue/scheduler
[noop] anticipatory deadline cfq (Expected Output)
