My first 2 Cyrus servers had 800GB partitions on a SAN.  However, that 
turned out to be a little big in practice because it takes a long time to 
backup 700-750GB of Cyrus mailboxes.  The new servers that I am migrating 
to now are using 500GB partitions.  Currently, I have 2 per server, with 3 
servers.  The config looks like:

defaultpartition: p1
partition-p1: /var/spool/cyrus/mail/data1
metapartition-p1: /var/spool/cyrus/mail/meta1
partition-p2: /var/spool/cyrus/mail/data2
metapartition-p2: /var/spool/cyrus/mail/meta2
metapartition_files: index cache expunge squat

My plan is to add additional partitions if they fill up, but I might also 
just add additional servers (these are running under VMWare).
