Configuring Your Hardware
This chapter explains sizing information for the following topics:
 “CPU Configuration” on page7
 “Disk Partitioning” on page7
 “Filesystem Configuration” on page7
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
AirWave automatically partitions the disk subsystem upon installation. You can override these values. Table 4
below lists the default partitioning and provides guidance for more advanced scenarios.
Filesystem Configuration
For AirWave, the NOOP File I/O scheduler provides the best random write performance. If you are running
AirWave 7.2 or later, 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)
