power utilization / heat production
Sean asked about heat earlier, here are some power consumption number based
on actual tests (on burn in or other test hardware). The results are slightly
lower than vendor prediction. Also note that burn3 and area51 are identical
hw other than one uses SCSI disks and the other uses SATA.
Note the whitesands machine is the "class" we're looking at for sites, the
two ancient pieces of sun hardware are what we've previously had in sites.
