Non-Optimal Links

NVIDIA UFM Enterprise User Manual v6.11.1

A non-optimal link is a link between two ports that is configured to operate at a certain speed and width and is operating at a lower rate. The Non-optimal links feature helps you identify potential link failures and reduce fabric inefficiencies.

Non-optimal links can be any of the following:

  • NDR links that operate in HDR, EDR, FDR, QDR, DDR or SDR mode

  • HDR links that operate in EDR, FDR, QDR, DDR or SDR mode

  • EDR links that operate in FDR, QDR, DDR or SDR mode

  • FDR links that operate in QDR, DDR or SDR mode

  • QDR links that operate in DDR or SDR mode

  • 4X links that operate in 1X mode

The Non-Optimal Links window allows you to set the preferred action for non-optimal links.
