AirWave includes the 64-bit CentOS operating system based on Red Hat Enterprise Linux (RHEL) and is
installed by default.
NOTE: If you choose to install RHEL instead of the supplied CentOS, you will need to purchase your own RHEL license and support
separately.
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 AirWave communicate with these devices?

NOTE: To ensure hardware capability, purchase server hardware that is certified to be compatible with Red Hat Enterprise Linux 5
(RHEL5).

Choosing Your CPU

For most AirWave installations, Dell recommends selecting high-performance Xeon X or W-series based CPUs.
Dell performs scalability testing using Intel based hardware at this time. See
CPU selection based on clock speed and core type.

Choosing Your Memory

AirWave's memory recommendations scale linearly with the managed device count.
