On a side note, Lennart, when you have 1500 servers, how do you arrange
for console access to a server if required to solve a problem with bios

In effect, the BIOS needs to support connecting to the 'console'
across a network. I don't imagine that's too common on generic
motherboard BIOSes.
It's common for server hardware to have network-accessible consoles.
Absolutely normal with 'traditional Unix hardware' (e.g. - Sun SPARC,
IBM pSeries, etc).
We've got HP Opteron boxes where one can capture BIOS output across
the network (rather needful when folks in Canada need to reconfigure
boxes in India). HP certainly "sells that"; I'll bet Dell does, too.
It may be more troublesome to get this sort of functionality on "beige
boxes" (even of the server variety).

Actually, a company called "Middle Digital" in Canada
(www.realweasel.com) has ISA and PCI console cards that do just that.
I have used them with whitebox servers for years and installed one
most recently two weeks ago. It makes handling the serial like a
"real" UNIX box easy. I have had very good luck with them. Not
troublesome at all and worth every penny.
