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.
OS Core Disable for Fault
Resilient Boot (FRB)
Isolates a faulty CPU during startup to improve system
reliability and availability.
Corrupt Data
Containment Mode
Identifies the memory storage unit that contains
corrupted data to minimize the impact on the running
programs and improve system reliability.
Socket disable for Fault
Resilient Boot (FRB)
Isolates a faulty socket during startup to improve
system reliability.
Architected Error
Records
With the enhanced machine check architecture
(eMCA) feature, the BIOS collects error information
from hardware registers in compliance with UEFI
specifications, sends the error information to the OS
over the APEI of the Advanced Configuration and
Power Interface (ACPI), and locates the error unit,
improving system availability.
Error Injection Support Injects errors to verify various RAS features.
Machine Check
Architecture
Provides software recovery for uncorrectable errors to
improve system availability.
eMCA: Gen2 Improves system availability.
Out-of-band (OOB)
access to MCA registers
The OBB system accesses MCA registers by using the
Platform Environment Control Interface (PECI). If a
fatal error occurs in the system, the out-of-band system
collects onsite data to facilitate fault analysis and
locating and improve system serviceability.
BIOS Abstraction Layer
for Error Handling
The BIOS processes errors and reports the error
information to the OS and 2288H V5 in compliance
with specifications to improve system serviceability.
BIOS-based Predictive
Failure Analysis (PFA)
The BIOS provides physical unit information for
DIMM errors, and the OS traces and predicts errors,
and isolates error memory pages.
