The aptly-named Thumper

No, really. Thumper. AKA the Sun Fire X4500.

It's a 4RU, 4-way x64 server from Sun with no less than FOURTY-EIGHT disks in it. Rather than the traditional RAID systems, where the disks all slot in the front and there's a whole heap of wasted space at the back, this beast (and I'm not using that term lightly) opens up, like a drawer, and you slot four dozen disks in vertically (taking getting perpendicular to a whole new level!). Weighing in at over 75 kilos, this isn't a light unit and it can provide up to 24TB in just 4 RU of vertical space. Able to deliver around 1 gigabit per second from disks to the network, this would be an ideal server for large amounts of high-definition video or other tasks that require an aggressive storage arrangement.
