I'm quite new here so I would like to say Hello to all of you .
For few days I've been reading documentation and forums but I still have some doubts. I'm interested in Open Edition of ZCS and here are my basic questions:
1. Is there any chance to run ZCS for 15000+ accounts on one server or do i have prepare hardware myself for multi-server installation? How powerful it should be?
2. If it's necessary how to distribute Zimbra components among servers for optimal performance and which component requires the most cpu, ram, and hdd?
3. OpenSource edition doesn't have load balancing, redundancy and backup options but as I understand I still have my own solution for backup of databases or data in mailboxes ? Is there possibility to set up multiple mta or mailboxes servers ?
Thanks in Advance
