RF Capacity

2 radios were “heavily utilized” 80-100% of the time.

(“Heavily utilized” is 80%+ utilization).

(Only “on time” is considered. That is, blocks of time the radio is doing something, not the middle-of-the-night).

AirWave 8.0 - Multi-server Architecture

Scale to 20,000 APs

• No architecture choice will prohibit > 20,000

• Up to that limit, add another server, get another increment of capacity (symmetric arch)

Single Virtual IP from perspective of controller/VC

• Controllers/VCs need be configured with only a single AMP IPaddr

Failover without human intervention

• Failover transition lasts 10min or less, during which time data collection may be interrupted

• Only data loss might be up to 1hr of client session data; no other data loss

• Simple process to re-introduce repaired server to cluster (or add another server)

Can still run on a single server
