planning for 15000 users in two locations?

[tiger2000]

Dear all,

just hope to get some advice on how to plan 15000 users who locates in two major cities?

currently planning to have:

location 1:
1 server for major LDAP
1 server for MTA + Mailbox(for users in location1), plus one external storage

location 2:
1 server for LDAP replica
1 server for MTA + Mailbox(for users in location2), plus one external storage

by the way, how about the disaster recovery? any advice on this?

Thanks.

Hi..one of the way to do this is explained in my reply at the following link.
Link is about the configuration management to handle the logical flow of email and system setup.
Multi-country secondary servers

You still need to read about scalability and other large deployment setting son wiki and in forum threads Performance Tuning Guidelines for Large Deployments - Zimbra :: Wiki
