Supported RAS features
Module
Feature
Description
CPU
Corrected Machine Check
Interrupt (CMCI)
Corrects error-triggered interrupts.
Memory
Failed DIMM Isolation
Identifies faulty DIMMs to facilitate
isolation and replacement of the faulty
DIMMs.
Memory Thermal Throttling
Automatically adjusts the memory
temperature to prevent the memory
from being damaged due to overheat.
Rank Sparing
Uses some memory ranks for backup to
prevent the system from breaking down
due to uncorrectable errors.
Memory Address Parity
Protection
Detects memory command and address
errors.
Memory Demand and
Patrol Scrubbing
Corrects correctable errors upon
detection. If these errors are not
corrected in a timely manner,
uncorrectable errors may occur.
Memory Mirroring
Provides high reliability for the system
via mirroring.
Single Device Data
Correction (SDDC)
Corrects single-chip multi-bit errors to
improve memory reliability.
Device Tagging
Degrades and rectifies memory faults to
improve memory availability.
Data Scrambling
Optimizes data flow distribution to
reduce the error probability and improve
memory data flow reliability and address
error detection.
PCIe
PCIe Advanced Error
Reporting
Provides a PCIe advanced error
reporting mechanism to improve server
serviceability.
UPI
Intel UPI Link Level Retry
Provides a retry mechanism to improve
the reliability of UPI links.
