Table A-3 RAS features
Module Feature Description
CPU Corrected Machine Check
Interrupt
Corrects error-triggered interruption.
DIMM Failed DIMM Isolation Identies a faulty DIMM and isolates it
from others before it is replaced.
Memory Thermal
Throttling
Automatically adjusts DIMM
temperatures to avoid damage due to
overheating.
Rank Sparing Allocates some memory ranks as
backup ranks to prevent the system
from crashing due to uncorrectable
errors.
Memory Address Parity
Protection
Detects memory command and
address errors.
Memory Demand and
Patrol Scrubbing
Corrects errors upon detection. If these
errors are not corrected promptly,
uncorrectable errors may occur.
Memory Mirroring Improves system reliability.
Single Device Data
Correction
Provides a single-device multi-bit error
correction capability to improve
memory reliability.
Device Tagging Degrades and recties DIMM device
faults to improve DIMM availability.
Data Scrambling Optimizes data stream distribution
and reduces the error possibility to
improve the reliability of data streams
in the memory and the capability to
detect address errors.
PCIe PCIe Advanced Error
Reporting
Improves server serviceability.
UPI Intel UPI Link Level Retry Provides a retry mechanism upon
errors to improve UPI reliability.
Intel UPI Protocol
Protection via CRC
Provides cyclic redundancy check
(CRC) protection for UPI packets to
improve system reliability.
System Core Disable for Fault
Resilient Boot (FRB)
Isolates a faulty CPU core during
startup to improve system reliability
and availability.
