    Default Real World Server Requirements

    Hi,
    I've read all the posts I could find on the forum in relation to what spec server to use for a particular userbase. I haven't been able to find a spec for anyone using a couple of hundred web-client users. It's not clear in the posts whether they are POP3, IMAP or webclient users.

    So the question is:
    If anyone is using between 200 and 500 AJAX webclient users , what spec server are you using,

    specifically - Processors , RAM and Hard-Disk type/array type

    As a starting point can anyone recommend or estimate how may webclient users could be succesfully hosted on a server with

    CentOS 5/RedHat EL5
    1 x Quad Core Xeon x3353 2.66Mhz , 2x6M cache, 1333Mhz FSB
    8GB dual-rank DIMM Ram
    300GB SAS 15,000 rpm RAID1 drive array.

    Thanks,
    Derek

    If you have room in the server box, I'd rather go with four SAS 146GB (and a RAID0+1) than two SAS 300GB.

    And I'd throw in two SATA2 500-750GB for HSM and backup.

    If you're short on money, then two SAS 146GB and two SATA2 500GB.

    Hi DerekB,

    Will this installation be using FOSS or NE ? If more users are going to be added later could you justify the cost of SAN/NAS ?

    Regards,

    Hi,

    SAN is out of budget at the moment, but we can have a second server as a cold standy.
    We would be using NE version.
    /opt/backup folder will be replicated to seconad standby server is case of disaster.
    server will probably be dell poweredge R300 1U. datacentre co-location prices in Ireland are very expensive hence the 1U limit at the moment due to budget.

    Nice little beast (shorter than a 1950 so housing costs less but available with hotplug HD and PSU). However, brand new...

    You're then limited to two 3.5" HD. So two SAS 300GB seems OK.

    Hi Klug,
    so do you think that server with 8Gb ram would comfortably host 200 to 500 users using webclient ?

    Do you have any real world examples ?

    Have you had a read through Performance Tuning Guidelines for Large Deployments - Zimbra :: Wiki ?

    Also, if you are looking to deploy ZCS NE then Sales/Support would help you with sizing I would imagine

    We have one customer hosting 300 users on a single 4GB server and another one hosting 700 users on a two servers setup (on server with 4GB for mailstore and one server with 2 GB for MTA).
