  • TDP == Thermal Design Power
  • Solaris Fault Manager is a key component of Predictive Self Healing. Solaris Fault Manager receives data relating to hardware and software errors and automatically diagnoses the underlying problem. Once diagnosed, Solaris Fault Manager automatically responds by offlining faulty components.
  • Intel continues to innovate to improve the MCA for better RAS and recovery (e.g., CMCI). Sun and Intel are working together to extend these capabilities to systems based on the Intel Xeon processor 5500 series, including chipsets and memory subsystems. Solaris recognizes and supports Intel Xeon processor 5500 series Machine Check Architecture (MCA).
