Sometimes this can be done, sometimes not, depending on the customer and
server setup.

Just telling people "well, get an extra switch and install lots of extra
cabling to get power redundancy" is not exactly what people want to hear.

We've been through lots of planned and unplanned power issues in the 
last year - and especially the planned stuff ("replace USV and power
distribution switch") is *very* much less painful with dual PSUs in 
every (critical) component.
