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) - Jussi Hirvi -- Jussi Hirvi * Green Spot Topeliuksenkatu 15 C * 00250 Helsinki * Finland Tel. +358 9 493 981 * Mobile +358 40 771 2098 (only sms) jussi.hirvi at greenspot.fi * http://www.greenspot.fi

I deploy public-facing machines using both it and Xen, and I can't really speak to any difference in performance or small-scall management. -- Paul Heinlein <> heinlein at madboa.com <> http://www.madboa.com/
