Mainframe-class RAS features
Reliability / Availability
•
Dual-Core Intel

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
