You caould also consider a multi-server setup, have a look at the documentation here: Documentation for the open source Zimbra Collaboration Suite; email, contacts, and group calendaring The other alternative is to use a Cluster for HA, don't forget that if you're running VM on a single ESXi server you still have a single point of failure in the ESXi server. |
Thanks Phoenix,
started reading Multiple Server Documentation on this lunch time.
So what I've to do (if I've correctly understand) is 3 Virtual Machines (LDAP Auth Server only, Mailbox Server only, MTA server only) + 1 Virtual Machine for Openfiler/FreeNas system (or a phisical server, or Hardware Nas) where my Mailbox Server have to point for it's stores (I've to mount external NAS volume I suppose).
This is correct , cannot speak about HA solutions, but it should be most performant then an all-in-one solution. If Esxi server crash we are stopped. If a virtual machine crash we can perform a restore of that specific snapshot and for datas in NAS we can provide surely a raid protection.
There is any way , with Zimbra O.S.E. , to perform a sort of "service continuity" in case one mailserver or component crash?
