I have a requirement from customer to deploy CWMS for 1500 concurrent users. Because of server limitation, i'm planning to deploy 6 CWMS size 250 user (6 x 250) rather than deploy 1 CWMS size 2000 user. Is that possible? How to combine 6 CWMS into 1 entity and to add HA to that deployment?
You cannot have 6x CWMS 250 user system act as a single system. As Richard mentioned, if you need a system with 1500 concurrent active callers, you should opt for 2000 user system. Additionally, like Richard mentioned, on a regular 2000 user system, you can have maximum of 100 callers in a single meeting. However, if you add High Availability, CWMS 2.0 supports up to 250 users per single meeting.
I hope this helps.
