Configuring Your Hardware
This section explains sizing information for CPUs, Disk partitions, and file systems, and it includes the following
sections:
l "CPU Configuration " on page 10
l "Disk Partitioning" on page 10
l "Filesystem Configuration" on page 10
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.
Default Partitions Size
boot 100 MB
swap 4 GB
/ Remainder of disk space
Table 4: Default Partitions
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)
