Regatta - technical definition

A high-end Unix-based pSeries server from IBM. Introduced in late 2001, the model p690 incorporates mainframe class self healing capabilities and partitioning to the pSeries (RS/6000) family for the first time. The Regatta also inaugurated IBM's Power4 chip known as "Spinnaker," which contains two processors running at 1 GHz. The copper-based silicon on insulator (SOI) Power4 CPU chips provide increased performance and use up to 66% less power than previous POWER chips.
