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 margins 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 that can influence the processing requirements for your AirWave server:
How many devices will the server manage?
l
How often will AirWave communicate with these devices?
l
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 E-series CPUs.
Dell performs scalability testing using Intel based hardware at this time. See
Matrix" on page 1

Choosing Your Memory

AirWave's memory recommendations scale linearly with the managed device count.
With AirWave servers running at full load for those device counts with a large number of floorplans, the
recommended memory usually results in best overall performance.
Best performance is defined by minimal disk reads due to sufficient caching, thus allowing for maximum disk write
performance and minimal CPU I/O wait time.
