Abstract :
The IBM Power6 microprocessor extends the capabilities of the Power5, dramatically increasing its ability to recover from hard and soft errors without increasing system downtime. The Power6 adds new mainframe-like features for enhanced reliability, availability, and serviceability, including instruction retry and processor failover. Optimized for performance and power, the Power6 implements these RAS enhancements without compromising ultrahigh-frequency operation.
