Hi guys
I'm about to embark on a project replacing a legacy single mail server running proprietary software with a cluster of Dovecot servers. We clearly need a shared mail store for these servers, but we are not happy with simply using a server running NFS as this becomes a single point of failure.

This is a hybrid of the two options, except a) it's a fully supported and stable NetApp configuration, b) they're sharing disk storage, c) you're not hog-tied to GFS, d) it's the best NFS implementation in the world (you can even

I have a six-digit userbase with mailboxes in this configuration.
Thanks for replying - our budget won't stretch to that sort of device, and it's possibly overkill in terms of storage capability (our mail currently fits in 100GB easily) but we do like the redundancy/HA features.
Are there any options with similar redundancy/high-availability capabilities but more in the mid-range market?
