Production Ready?

[flateric]

Is anyone using Zimbra in a production environment. I must say I am extremely impressed with what I have tinkered with so far. I am actually in the process of building a new mail server for my company, and was wondering about the scalability of Zimbra. I know all the underlying components of Zimbra scale perfectly fine, Postfix, Ldap, Cyrus, etc. but as a whole is Zimbra going to run ok on a Dual Opteron with 2gigs of RAM, SCSI RAID. I am only supporting about 300 or so users, but our current mail server sees about 10K messages a day.

Also I have yet to get Zimbra running correctly on RHEL4 x86_64, I guess I will have to build from source and see how that goes. Is there going to be an easy upgrade path when newer versions are released?

Keep up the great work.

We run it in production here at Zimbra

I assumed as much, what kind of volume do you guys see? I noticed your demo servers run on opteron hardware, do you guys run rhel x86_64? Did you install from source, or do you have some x86_64 rpms laying around somewhere??

We run 32bit just because as a whole 32bit is battle tested. See this thread for more info:

Install on 64bit Fedora

We use the binary version of the Red Hat download. 300 users should be fine on a box like our demo hardware. 10k messages per day isn't the much. It's way less than 1 msg/sec across the whole day.

So assuming you have the 32bit libs installed you can run on 64bit RH in compatibility mode.

today in the span of 24 minutes we got 14,499 emails in all sizes from 1 kb to 600 kb. all messages were received and none were corrupted. in addition we also logged in to the imap server from many separate clients at the same time as well as via the web front end. all emails showed up everywhere, without any issues.

i've been running it for more than a month now, and we average about 5000 emails per hour, i know that thats not alot, but i have yet to see any minor glitch.

Can you tell us about the hardware you are using so that we can capture the hardware and performance combination? Thank you!
