License Server ScalabilityLicense Server Scalability

Scalability Considerations• CPU

– License server is a single threaded process– 170 client log-ins/second = 306,000 log-ins in 30 minutes

• Bandwidth – start-up, checkout, heartbeat & refresh• Memory – # of licenses checked out• Hard Disk – License server & LMC and usage logs

Other Considerations:• Licenses CANNOT be shared across license servers • Licensing subsystem not backward compatible

License Server – License Server – Addressing Single Point of FailureAddressing Single Point of Failure

Redundancy– Active Alerting

– 30 Day Grace period

– Microsoft Clustering of License Server

– Easy license service host replacement (host name) & easy license backup and restore
