    Default Capacity Planning for 1000 Users

    Hi !

    I want to implement ZCS 6.0 for about 1000 users.

    The daily email traffic:
    -. Incoming: 10000 mails.
    -. Outgoing: 4000 mails.

    I am going to use hardware:
    2 x Quad-Core Intel Xeon.
    8 GB RAM.
    250 GB Hard Drive.

    Is the hardware specification adequate to handle the email traffic for 1000 users?

    CPU + RAM should be sufficient. But you don't mean a single 250GB HDD, right?

    Make your hdd Raid, hardware Raid is better. Also, whats your monthly bandwidth plan and port speed ? Thats also an important factor in Capacity planning.

    You should be going RAID 10 for performance. If that's a single drive or RAID 1, I wouldn't put my money on it keeping up.

    Remove one quadcore (depending on quadcore) and go for RAID10.

    The storage subsystem is the key.

    and then remember for every meg you store, you need a few more for backups. but obviously not on the same machine and not as fast.

    Thanks for your advice all !

    It's actually 2 x 136 GB HD. I need to buy two more HDs for implementing RAID 10.

    @vbn:
    I have 8-Mbps dedicated line.

    @dave_kempe
    Some friends suggest me using virtualization to do hot backup. What do you think? Is there any other way to do hot backup, especially for the mail data?

    I would say thats a bit tad on the lower side. Wierd number though
    Usually its multiples of 10s....10Mb,100Mb,1000 and so on

    Depends on what the average email payload you are looking at .. maybe around 2 MB ? Is it restricted to 8 bothways...in and out ?

    It is the Internet bandwidth. For LAN, of course, it's 100 Mbps.

    It is 8 Mbps IN and 8 Mbps OUT.
