We are thinking of two Sun's Thumper X4500 servers for a fork lifting upgrade to our IMAP servers. The x4500 is relatively new but a few reports on the Internet gave it a thumb up, particularly on the use of ZFS and IOPS of RAIDZ.
Mail is one of the application cited by Sun for such a box. We have about 30k users with various size of mailboxes. Any experience or opinion regarding the use of such hardware for IMAP server will be helpful to us.
