MultiServer Install

[Mo_Hong]

Hi all,
I would like to receive some tips for a challenge we have. What are the hardware specs you would recommend for a MultiServer Install to handle from 20,000 to 50,000 accounts?? please we would like any tip or installation experience.

Regards,
E.

You'll need to include more detail to help characterize the load generated by each user. IE, how big is each mailbox, whats the average message size, how many users are logged in concurrently, etc.

Thanks for the reply, I'll try to be more specific:

1.- Mailbox Size: 60 % 15Mb, 40 % 50Mb and like 200 to 300 mailboxes Unlimited
2.- Avg. Msg Size: We want to keep it small, about 200 kb to 500kb tops, probably some of the IT administrators could have 1 to 2 Mb size messages.
3.- Concurret Connections:We think they are going to be from 2000 to 5000 concurrent connections, probably this can be from 15 to 20 % higher.

Thanks in advance,
E.

here's somewhere to start:

Disclaimer: I'm not the perf master, just want to give you a starting point. I'm sure others will chime in.

The setup described in the document sounds like overkill for your needs. The machines described in the doc or something equivalent should be more than adequate and give you plenty of room for growth.

Dual-CPU Dual-core AMD Opteron 280 2.4GHz (4 logical CPUs)
8 GB RAM

For a loaded 50K users machine with average mailbox size of 30MB, your users will have about 1.5TB of mail, which is somewhere in the 3-3.5TB of disk space across the message store, database and index store. Based on your performance & reliability requirements, if you are going to use clustering, if you have existing storage hardware (SAN) etc, you'll need to find the best storage solution. As a tip, if you have the freedom to choose, more smaller drives are better than fewer bigger ones as they can do more in parallel.

Sound like for your workload, you could do it all with a single server (this is a hunch, not a result of performance testing).

Sam,
Thanks for the info. I'll give it a try to see how it turns out. If you have any other information that might be useful, please send it over to have a look at it.

Thanks,
E.

The Soapgen testing tool described is not currently
part of the Zimbra Collaboration Suite release, but can be made
available to Zimbra partners and service provider customers interested in
reproducing these results or creating their own benchmarks.

[DanCody]

Yes, that's something we'd be interested in. Should a request be made through the support system?

Hi Dan-
Sent a note to Kevin, and he should be able to help you on this.

Thanks
