Structure of servers to 250 accounts with 600GB of data

[edisoti]

Hello everyone,

precise guidelines for choosing a good structure.

I have two servers, a quad Xeon + 8GRAM Cord, 6 and 74 Xeon SCSI 3 disk Sata 160G 4GB RAM, I want to import all arquvios. PST and delete the outlook of all.

Doubt: What scenario would be better? How would the logic of installing Zimbra? How to have high performance and redundancy at the same time?

I don't mean to be unhelpful, but for that size of environment and the critical role email surely plays I'd consider calling in a consulting service to help you plan this out.

With 600GB of data, SATA disks will be slow - unless you have an awful lot of them and do things like mount /opt/zimbra/store, /opt/zimbra/db and /opt/zimbra/data/amavisd/tmp on separate RAID1 (or RAID10) arrays.

A single faster Quad-core Xeon should be fine, but if running 64-bit and if most users will be logged in all the time, I would add more RAM for performance.

Hope that helps,
Mark

So, I have two Xeon 3.0 and 12 GB RAM and SCSI disk 6, with 5 64Bit Debian, I set up Raid 1 for OS and RAID 10 for the structure of Zimbra, I put these two machines to work together because of redundancy, but what data zimbra, would use the RedHat 5 and Zimbra Network because of the Cluster? The open source version would have this option? LDAP and Replica would cluster in MySQL?

I'm sorry about my English!

Configuring the server is just PART of the discussion;
How are you going to back up the data? What about recovering from a drive or server hardware failure?
The problem is just ONE server - what do you do if you have a hardware failure? will 250 people come and visit/call you? as you say "I'm ordering a part..(!)

You're right, you need redundancy somehow, but it's harder without a backup server... One cool option is here in a how-to - it lets you set up a "mirror" server and smtp-sync data across to the backup server - (if you have a failure, you at least have a running server with all the data (up to an hour or two stale)
(thank you Cosa!)

Still need a 2nd machine (smaller is ok), and it doesn't give you historical backups, just redundency.
