Multiple Server Installation in HA environment?

[tiger2000]

Dear All,

Zimbra supports multiple server installation which is great. For instance, we can have several servers which run as : LDAP, MTA, Message Store. like :

LDAP x 1 server
MTA x 2 servers
Message Store x 2 servers
=======================
Total 5 servers

and my question is that : can we run HA mode for MTA and Message store servers, which looks like :

LDAP x 1 server
LDAP replica x 1 server
MTA (Active) x 2 servers
MTA (Stand-by) x 2 servers
Message Store (Active) x 2 servers
Message Store (Stand-by) x 2 servers
==============================
Total 10 servers

Does Zimbra NE edition support such feature?

any comment will be highly appreciated.

Thanks.
Rgds,

The only officially supported HA mode is on Red Hat Cluster Services.
