    Default Migration from solaris 8 cyrus+horde to Ubuntu 8.04 Zimbra Comm 6.06

    I finished migrating from two Sun Servers running Solaris 8 and CyrusSASL+Horde to a Linux Ubuntu 8.04 x64 Sunfire 4250 2xQuad Core Intel E5450, 14x146 GB RAID1-0, 32 GB RAM.

    Migrated about 50k accounts with a external MTA+Spamassassin + External LDAP.

    Working with a 200 simultaneous web conections and 90 IMAP/POP simultaneous.


    All works smooth and quickly. I going to wait some months to delete the unused accounts because cyrus dont give me a log to check it!

    Do you feel the hardware requirements are still adequate? We are approaching the same task.

    Default

    yes... its works well.. I only see an increase of load when i send a email to all my users.
    Zimbra use a lot of memory. Maybe u could increase the RAM a little (from 32 to 48 GB).



    My Cacti show:

    I have a load average:
    1 Minute 0.13
    5 Minutes 0.75
    15 Minutes 0.18

    CPU Usage avarage:
    System: 1.04
    Nice: 0.00
    User: 5.41

    TCP Connection STatus Average:
    Established: 172.82
    Listen: 24.98
    Time Wait: 22.67
    Close Wait: 10.13
    FIN WAIT1: 795.45m
    FIN WAIT2: 8.87

    I hope this info is usefull for you.
