- Mainframes tend to be used at about 90% utilization (Wikipedia). I already knew that mircocomputers tend to be used at 10% utilization.
- Google Image search informs me the the adjective "mini" is applied to everything from actual minicomputers to hand held devices.
- At one point there were over 100 companies making minicomputers (Blog found on sun website).
- The distinction between "mainframes" and "supercomputers": supercomputers tend to focus on raw processing, Mainframes I/O (various).
What annoys me is that I may have seen a picture of such a distinctive computer in the past. My first guess (due to the black case) was IBM, but IBM tends to use Blue, rather than red highlights.
Are those grey boxes in the background some kind of Network Attached Storage?
6W per disk x 8 disks per box x 6 active boxes = 288W (not bad now that I worked it out).
Big cube-of-cubes: Connection Machine CM-2 supercomputer. (Unfortunately, empty-CM2-cabinet, to be precise.)
Wall of smaller grey things: Sun E4000's. 14 CPUs apiece, circa 1997.
In the good-old-days, supercomputers were actually a subset of mainframes. That doesn't hold true for massively parellel MIMD machines though, which is what almost all modern "supercomputers" are. (I don't think they really qualify as "supercomputers" either, they're just clusters.)
