[Dovecot] High Availability strategies

[Ed W]

I think there is a whitepaper from Dovecot's current main sponsor 
(before they were called Rackspace) which described their architecture 
using pairs of servers and DRBD between them.  Each server is moderately 
loaded and active.  If one server fails then half the users don't notice 
and the other half get switched over to what is really their slave server.

Seemed like an elegant architecture...

Is this stuff archived anywhere Timo?
