This is a document about how to set up a redundant virtual server solution using iSCSI, RDAC, XEN, Multipath, 2 x Dell 1950 Servers and Dell MD3000i SAN. The distribution chosen for this, is my distribution of choice, Debian Stable (4.0 / Etch). I assume you have some knowledge of Linux, specifically Debian. YMMV on other distributions. with completely empty machines.
