Installing Zimbra
Hardware
For a production server running ZCS, and assuming that this is a standalone box running no other network services and servicing 100 users, you will need the following:
•A current 32-bit processor of at least 2.0 GHZ (Intel or AMD). For MAC OS X users, the processor should be G5 or better, Intel Core Solo, or Intel
Core Duo.
•At least 2GB of RAM. (However, 4GB is recommended.)
•10GB free disk space for software and logs.
•Additional disk space for mail. I usually assume 500MB of mail per user. So at 100 users, I would recommend at least 100GB of disk space for mail. Why not 50GB (50*100)? Because you need space for your backups. Zimbra stores only one copy of an attachment sent to several users (that can save a lot of space) but needs space for its databases (indexes, etc).
•As the email server is a mission-critical application for any enterprise, I would recommend some sort of hardware fault-tolerance solution. A rule of thumb is that RAID 5 is OK for 100 users. As the organization exceeds that number, RAID 5 is not recommended. Scalability white papers are available on Zimbra's website (for single or multi-server installs).
Software
Zimbra Collaboration Suite Network Edition supports the following operating systems (end of July 2007):
