    Default 2000 user capacity planning

    I've perused the wiki and this forum looking for ideas as to how fulfill the hardware requirements for a 2000 user Zimbra Network Edition deployment.

    The mandate is to look for a single server solution, which I think is somewhat realistic(maybe). What I'm missing is the max # of concurrent users anticipated to hit the application and the mailbox size limit per account. Clustering is a possibility.

    For right now, I'm assuming 500 concurrent users. All of them web client users.

    Two Opteron Dual core CPUs
    RedHat ES 4 64-bit
    4GB RAM
    250GB SATA RAID1 or 300 SCSI RAID1 (RAID 0+1 might not be an option)

    Any feedback is appreciated.

    In my experience, i recommend: minimal 8 GB RAM,,,, 12 GB RAM is OK,,,, and 16 GB RAM is very powerfull...

    If you're going to use any RAID then use a RAID10 for better performance.
