Dunno, I could be exaggerating a bit :) The newer cabinets you get from
Sun have space for eight "photon" arrays. I think a photon array has 22 9.1
or 18.2 GB 10000RPM disks, each with a wee Ultra2-scsi connector, on it.
Then, each photon has a fibre cable coming out the back, into a
concentrator at the top of the cabinet, which feeds to a beast of a
machine. They cabinets are quite pretty. When you take the doors off, you
see 88 little flashing lights blinking at you. It's like a cybernetic
christmas tree. And the same around the back of the cabinet.
22*8*9.1 gives about 1.6TB of storage. There are three cabinets, and a few
small ones with disk arrays that just house boot disks. Suppose it's the
best part of 5TB in total - there are three cabinets off one of the
machines. And no, it's not used for storing MP3s.
