392 Troubleshooting and Recovery
• Problem: The least priority servers lost power after a PSU failure.
–
Resolution: This is expected behavior if the enclosure power policy
was configured to
No Redundancy . To avoid a future power supply
failure causing servers to power off, ensure that the chassis has at least
four power supplies and is configured for the
Power Supply
Redundancy
policy to prevent PSU failure from impacting server
operation.
•
Problem: Overall server performance decreases when the ambient
temperature increases in the data center.
–
Resolution: This can occur if the System Input Power Cap has been
configured to a value that results in an increased power need by fans
having to be made up by reduction in the power allocation to the
servers. User can increase the
System Input Power Cap to a higher
value that allow for additional power allocation to the fans without an
impact on server performance.
