You're worried about heat and stressing the power supply, I'd guess. The other
thing is that while the internal disks are on "wide" (16-bit) SCA connectors,
they're not hooked up "wide" to the SCSI controller, so they max out at 10MB/s
channel (of course, the disk may or may not be able to deliver in excess of
that, depending upon how old they are) - if you want the 20MB/s performance one
can get from wide SCSI, one has to hook up the disks in something like Sun 611
cabinets to a wide Sbus SCSI controller. That will also remove them from the
cabinet (reducing heat load) and remove them from the power supply load.
