Description
Identifies the memory storage unit
that contains corrupted data to
minimize the impact on the running
programs and improve system
reliability.
Isolates a faulty socket during the
BIOS startup process to improve
system reliability.
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.
Injects errors to verify various RAS
features.
Provides software recovery for
uncorrectable errors to improve system
availability.
Improves system availability.
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.
The BIOS processes errors and reports
the error information to the OS and
the server in compliance with
specifications to improve system
serviceability.
The BIOS provides physical unit
information for DIMM errors, and the
OS traces and predicts errors, and
isolates error memory pages.
