Dear All, Currently we are running a mail system for 10000 users each 2GB mailbox. At present we have 5 mail servers where users mailboxes are distributed almost uniformly. We have a HP SAN Storage (HP EVA 6400) where mailboxes are stored. We partition the storage into five vg and each is mounted on the 5 servers. We are using postfix and dovecot.
The system was running fine but currently we notices high IO load due to IMAP connection. So we are planning to build a dovecot cluster. Please suggest some design for the dovecot cluster keeping in mind to our scenario. (If needed we can buy additional hardware like load balancer). With Thanks and Regards -- Jeherul Islam India
