When sizing a storage device for a large cyrus server, the typical question asked by storage vendors is what is the IOPS required per mailbox M$$ Exchange has this concept of IOPS. and they suggest 1.5 IOPS per mailbox ( heavy users ) If I use postfix and cyrus , on my imap server ( pure IMAP server .. All spam filtering , outgoing mails , authentication etc happens on different servers ) If the storage is used only for imap storage , what is the typical "IOPS" requirement per user We will probably assume 30-50 mails a day of average 100k , and an email client checking for new mail every 5minutes ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
