Mainframe-class RAS features

Reliability / Availability

Dual-Core Intel® Itanium® processor:

Error handling of hardware and operating system through Machine Check Architecture (MCA)

Memory mirroring: Continuous operation even in the event of a non-correctable error

Partial Chipset degradation: Avoid multi-partition shutdowns resulting from chipset failures

Highly Available Center Plane: System restoration after the replacement of a failed crossbar no longer requires a system shutdown

Complete modularization and redundancy: Improvements in fault resilience, continuous operation and serviceability

Clock modularization, redundancy and 16 processor domain segmentation: Minimizes downtime, and avoids multi partition shutdown due to clock failure

Diagnostics of the error detection circuits: Substantial strengthening of data integrity

Enhanced error detection of the high-speed interconnect:

Intricate error handling through multi bit error detection and retransmission of error data

Two independent power sources: Avoid system shutdown due to failures of the power distribution units

Serviceability

Autonomic reporting of logs with pinpoint prognosis of failed components allow for the realization of mainframe-class platform serviceability
