    Default Zimbra Cluster Validation?

    Hi,

    I'm looking a Zimbra cluster scheme installation and i thinking in the next solution:

    2 Ldap Server (master and replica)
    4 MailStore Servers (with SAN Connection)
    2 Mta Servers
    2 Zimbra AS/AV Servers

    This is scheme correct?

    Some questions about this scheme:

    1. I need the others server are connected to a SAN or the data could be locally?
    2. For MTAs, i considering separating for AS/AV servers... its ok? or can i install 4 MTAs with Zimbra AS/AV.
    3. For Load Balancing... i need to install the zimbra-proxy on each servers? or can i install i dedicate zimbra-proxy (on its own server) but in this case how can i resolve the high avalability? and which services or servers are covered with zimbra-proxy?

    thanks

    It's "cluster" as in "multi-servers setup", not as in "High Availability", right ?

    Yes, looks nice.
    How many users do you intend to provision on each mailstore servers ?

    There's a spreadsheet you can get from Zimbra and/or local VAR to help you out on this (provisionning, SAN, etc).

    They can be locally.

    I'm not sure to understand what you're trying to achieve.
    What would you like to do ?

    Load Balancing does not exist within Zimbra.

    The Zimbra Proxy will allow you go give a single URL to your users (http://zimbra.domain.tld) and "hide" several mailstores behind it.

    A user's mailbox is "attached" to a mailstore : it's created on a mailstore and is not accessible from the others ones (even with SAN).

    If you want to do HA, you need to use RHCS (Red Hat Cluster Suite) or Veritas Cluster.

    HA can be done either with two nodes (all services on each node) or with "lots" of nodes (one service per couple of nodes).
