Hear, hear! We found Dell servers were big-time underperformers.
Generic hardware put together with generally the same brand names of
components (e.g. - for SCSI controllers and such) would generally play
much better.
For the cheapo desktop boxes they obviously have to buy the "cheapest
hardware available this week;" it sure seems as though they engage in
the same sort of thing with the "server class" hardware.
I don't think anyone has been able to forcibly point out any
completely precise shortcoming; just that they underperform what the
specs suggest they ought to be able to provide.
