    Default Zimbra System Requirements

    I need to prepare a server specification for a particular Zimbra server deplyment.
    I get Zimbra Deployment Worksheet and entered requirements information.

    I get this:

    As I understand it is recommended use of 5 different role servers.

    What if I want to use only 1 physical server?

    500 mailboxes (max 2 GB in size)

    I think it would be possible on one high performance server with 32 cores, 64 GB RAM, SCSI HDDs, ...

    Most of important is the level of spam which you will receive.

    The recomendation of first is good, but be careful with the hard disk space. If you use Network Edition the backup system of Zimbra can take very long space of hard disk.

    For example in one of my server of production (160 accounts) with 744GB of space we use the 69% of space, in this server we have :

    [root@zcs ~]# df -h
    Filesystem Size Used Avail Use% Mounted on
    /dev/sda3 18G 4.9G 12G 30% /
    744G 486G 220G 69% /opt
    /dev/sda1 99M 24M 71M 26% /boot
    tmpfs 2.0G 0 2.0G 0% /dev/shm

    the problem always is the size of the backup:

    345G /opt/zimbra/backup
    5.3G /opt/zimbra/index
    128G /opt/zimbra/store
    3.1G /opt/zimbra/db
    135M /opt/zimbra/log

    to solve the problem, we decided to change the time of remove backups from 1m to 10d:

    [zimbra@zcs ~]$ zmschedulebackup
    Current Schedule:

    f 0 1 * * 6 -a all --mail-report
    i 0 1 * * 0-5 --mail-report
    d 10d 0 0 * * * --mail-report
