Hi list,

would briefly like to get your ideas on this. I understand this is a
subjective matter, but I'd like some pointers anyway.

I'm planning to make a HA Xen solution based on DRBD and Pacemaker, mainly
serving as a disaster recovery solution for my customers.
have you tried drbd with xen?

yes, that's what I'm saying

It will daily sync their files and mails (rsync, imapsync) and in case of
disaster they can access this info by means of web based applications.

So I'm basically looking for a budget friendly rack server with good Linux
support (will probably be using SLES11).
I'd actually suggest you buy a third one, with lots of internal disks,
and install whatever OS you're familiar with to act as block storage
server. Example: openindiana + nappit + iscsi, SLES + aoe, etc.

That would be a single point of failure, rendering the "frontend" cluster kinda useless, except for load balancing. I plan to go for dual primary - cost is an issue, so limitation to two servers is key,
