Hi, Has, or does, anyone use dm-cache - specifically for caching SAN based storage locally? I'm looking for a way to speed up SAN based storage on a CentOS 5.6 + XEN Hypervisor which uses iSCSI mounted SAN storage. dm-cache seems like it do the trick, but I've never heard of it before until someone mentioned it in another mailing list.

Thus I can't just send out emails from this server but need to relay it via our ISP's SMTP server, which is very unreliable. Now
