Hi all,
I plan to run a dovecot IMAPS and POPS service on our network. We handle about 3 000 mailboxes. I thought first buying a topnotch server (8 cores and 16 Go RAM) with equalogic iSCSI SAN SAS 15K for storage backend.
On second though (and after a comprhensive read of dovecot features), I saw in http://wiki.dovecot.org/MailLocation that index files can be created on a separete local filesystem. My question is : for 3000 users, is it possible to have only a SATA backend attached to my topnotch server (to handle bigger mail quotas) by storing index on local hard drives (SAS drives) ?
Extra question, what is the better : iSCSI SATA backend or NFS share ? NFS share is more convenient to have a failover server.
Thanks for your help.
