8 | Selecting Your Hardware Components Dell PowerConnect W-AirWave |Version 7.3

The following table lists the minimum specifications required to run AirWave.

Dell PowerConnect W-AirWave includes the 64-bit CentOS operating system based on Red Hat Enterprise

Linux (RHEL) and is installed by default.

Your hardware should incorporate margin for WLAN expansion as well as future AirWave features and modules.

These recommended specifications are formulated to keep AirWave running on the same hardware platform for

up to three years.

Factors which influence the processing requirements for your AirWave server:

 How many devices will the server manage?

 How often will AMP communicate with these devices?

Choosing Your CPU

For most Dell PowerConnect W-AirWave installations, select high-performance Xeon X or W-series based

CPUs.

Scalability testing uses Intel based hardware at this time. See Table 3 for recommendations on CPU selection

based on clock speed and core type.

NOTE: If you choose to install RHEL instead of the supplied CentOS, you will need to purchase your own RHEL license and support

separately.

CAUTION: To ensure hardware capability, purchase server hardware that is certified to be compatible with Red Hat Enterprise

Linux 5 (RHEL5).
