Just wondering how to properly size a large install for 1200 users. I notice that the max port density is 32-40. Is that per server or can you have more than 40 on a single server. If 40 is the limit I assume you keep adding servers till your requirements are met.<br><br>Next, is there a basic ratio of users to ports to start with?<br><br>Finally, as far as redundancy goes; If I have 3 Unity boxes and a CM cluster of 3 servers. Can one single Unity server sit there waiting in failover for any of the other 3 Unity boxes to fail?<br><br>Thanks,<br><br>Paul.<br><br>
