Database: MySpace has a 20-terabyte (TB), scalable cluster of Isilon IQ 1920i servers. (A terabyte is 1 trillion bytes.) The cluster stores users' uploaded media files (images, videos, songs), among other things. It runs on 3.2-GHz Intel Xeon processors and has 10 server nodes storing 1.92 TB each. The nodes communicate on the InfiniBand architecture, which establishes point-to-point, serial connections between each server node. Isilon reports that data-transfer speeds are in the neighborhood of 3 GBps.
