    Default Users & server specification

    I'm seeking to install Zimbra (OSS or Licensed version, any suggestion is welcome) in a server with the following specifications:

    - Processors: Two Intel Pentium 4 CPU 2.80GHz, 1024 kB cache

    - RAM: 1GB

    - OS: Red Hat Enterprise Linux ES release 4 (Nahant)

    - Disk set: 68G, 76M, 505M, 244M

    I would like to know what is the active/concurrent user accounts i can handle with a server like this.
    I expect to manage a lot of user accounts (approx 4000), if the above cannot handle such quantity of users, what should i add to my system?

    Thanks in advance.

    If you look around the forum you will notice that there are any other factors at play here. How many messages are sent per day? What interface will they be using IMAP, POP, AJAX, MAPI? Are all messages going to be stored on the server?

    You'll want to have at least 2GB or RAM, if you really expect to have 4000 user's you may want 4GB of RAM. If these are heavy mail user's or you get lots of spam you may need to split the install into two servers.

    Thanks both of you for the reply,

    To answer Rsharpe questions:
    - The server must handle about 40000 message sent per day (average 1800 Mb transferred)
    - Using as interface AJAX, IMAP & POP
    - All messages stored in the server

    Can i have Zimbra working in a server with the above specification if I increase the amount of RAM and maybe split in two servers as KevinH is saying? I guess i will need more disk space too, correct? Any other suggestion?

    Thanks again

    The amount of disk space is driven by how much quota you'll give users. You'll also want to make take the number of disks into consideration. Having more smaller disks is always better for performance as the IO load will be spread out over more spindles.
