Q: How do you size an Airwave server given your environment?
ASE link: Go to the solution
A: BETA SOFTWARE
Please note this is an Aruba Networks beta solution. Sizing is determined by finding the closest engineering tested benchmark and then calculating the percentage difference between the requested device count and the benchmark. Environmental modifier adjustment amounts have not been fully qualified yet; this is a work in progress.
SUMMARY
Proper sizing of AirWave servers for performance and scalability is critical to ensuring usability. This calculator will assist you with making sizing decisions for AirWave servers. This does not support clustered sizing yet.
AIRWAVE 8.0 AND ABOVE SOFTWARE VERSION(S) REQUIRED
This sizing information is intended to be used for AirWave 8.0 and above single server deployments.
