I need to restructure my server farm from tower PC:s to a minimal amount of 1U rack servers. I am going to rely on xen virtualization, as KVM seems not to be very mature yet.
My current problem is the mail server, which uses a lot of CPU and I/O. A dedicated machine would be the best option. But would there be any sense in this:
- run the mail server in xen dom0 (to get full native performance)
- append a couple of light-weight servers as domU:s (like name server)
I don't know if it's recommended that way but at least it works fine.
