    Default Zimbra 7 System requirements for 2000 users

    Hi ,


    I am planing to install zimbra 7 for 2000 users on a single server. I thinks single server installation is OK for 2000 users? what do u guys think of it?

    Your ideas are welcome...

    I expect to have a 16 GB or 24 GB RAM . Processor Xeon 5600 series - 64 bit. 2 network Cards. 4TB HardDisk since one mail box quota is 1 GB.

    anyway what is the Raid level should I use when one mail box quota is 1 GB. i.e 2 TB for 2000 users.

    I found the below URL. but it is for Zimbra 5.

    System Requirements for Zimbra Collaboration Suite 5.0


    Since I install zimbra 7 - 64 bit version, could you pls answer the above questions?

    Did you look at some of the threads in the forums that cover the recommended hardware for an installation of your size?

    Yes, I found. here's the URL
    2000 user capacity planning

    I think My hardwarfe is OK. I need to disscuss about raid. in the above URL it says use RAID10 for better performance. any other raid level you recommed?

    this URL
    http://www.zimbra.com/docs/os/latest...uirements.html

    it says

    RAID-5 is not recommended for installations with more than 100 accounts.

    Your ideas are welcome. This is for Zimbra Opensource Edition.

    watch out for this 1GB quota. They might tell you this now but that will fill up in less than 6 months. You should really look into scaling during the architecture of this system. Putting 2000 users on hold while you are adding storage or switching servers is not easy. Also, file retention and backup will be a big issue. I highly recommend a SAN backend that you can easily increase and provision storage. Also look into virtualizing zimbra and giving that VM plenty of VCPUs and Memory. The snapshoting and cloning to test for upgrades will really help you out. Private message me if you need more help.

    Best,
    Leo
