Configuring Your Hardware

This section explains sizing information for the following topics:

l "CPU Configuration " on page 5

l "Disk Partitioning" on page 5

l "File System Configuration" on page 5

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 3 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

Default Partitions

File System 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)
