How to properly store email data

Posted on 2006-07-07

We are looking to set up some sort of redundancy on our email servers but are not sure how to proceed. We want at least 2 servers for email (pop3) and the mailboxes would need to be shared by both servers at the same time so that whichever one gets the email puts it into the mailbox. It seems as if a SAN is the only way to have truly redundant storage of any kind (besides DAS). Am I wrong? Is there a better way?

I would create a Backend Cluster, 2 Node connected to SAN, and, in front of that, I would put a FrontEnd Server running only the Services Required, like, as you stated, POP3 and IMAP, or OWA. If you are heavily loaded, then you can NLB the FrontEnd Servers !

Best Regards !

No, no ! Backend Cluster and Frontend NLB, Different things . . .

Backend Servers is were you keep all the mailboxes, and where all users access directly Via-Outlook Client.

FrontEnd Servers is where you Want your employees to Remote Access via Pop3, Imap, OWA, OMA, ... from Remote Locations. So, they sign in to the FE Servers and then are redirected transperantly to their mailbox, wether it is on Cluster Node 1 or Cluster Node 2. ( AD will know how to do it ).

Regarding the San, you can aim for a Dell /EMC CX300, which is very good and not that expensive . . .

You do not say what software you have the mail on nor even which OS you are using. If it's Windows you might be best getting two similar servers and replicating between them with NSI doubletake.
