The UltraSPARC T1 Processor - Reliability, Availability, and Serviceability

The UltraSPARC T1 Processor - Reliability, Availability, and Serviceability

By William Bryg & Jerome Alabado
December 2005

From Conclusion:

Combined with system RAS features such as redundant hot-swap power and cooling, and the Solaris 10 operating system's fault management architecture, next-generation processors like the UltraSPARC T1 processor promise to exhibit very high levels of reliability, availability and serviceability. Moreover, since one radical CMT processor chip replaces what formerly would have been many different parts in an SMP system (including multiple processor boards together with all of their associated external interconnects), the result will be a dramatic rise in overall system reliability and availability, corresponding to the greatly lowered part count typical of systems built with radical CMT processors.
