server numbers and partition size planning?

[tiger2000]

Dear all,

i know this may not have a right answer but if we're planning a site which has about 20000 users. will you recommend just run whole users in one single server or at least 2-server?

the second question is about partition size, according to the mail quota planning, it needs almost 2TB available size. in terms of performance, will you recommend to use multiple message-store such as 1TB first, and then 1TB next....etc. or just create one 2-TB partition?

(we will run the community edition : ZCS 6.0.x)

Thanks

First and foremost, read the docs man. Saves you a lot of trouble dude....
Documentation for the open source Zimbra Collaboration Suite; email, contacts, and group calendaring

More specifically

Finally, ZCS is at version 7.1.3 why would you start life with version 6. Just my $0.02

Go forth and Zimbra the world man
