Zimbra for 15000+ users

[aerojasc]

Hi There,

I'm writing because I recently receive a request to make an installation of Zimbra Collaboration Suite for a 15000 users environment. I would like to know witch is the best hardware to perform such installation. And witch is the best configuration of this hardware to avoid service interruption.

Thank's in advance for your help.

If it is a corporate environment you may want to consider a cluster setup. I have been looking at the SUN 4150 galaxy range - Sun 4150 They have 2 x quad intel xeons and can stuff in plenty or RAM. They also have the ability to fit in 8 x 10k disks giving you plenty of disc I/O. Your only consideration would be what type of storage you require for the mailboxes? Do you have SAN storage that you can attach?
