NC550SFP 10GbE No buffers errors

Hi experts,

  I run dl980 with 2 * NC550SFP dual ports and I found when my network workload increases, intermittent link down occurred with No buffers errors. check it out.

 

  Unfortunately, the problem re-occurred at 9/27 03:00am. However, I am lucky to find out the source of the problem: network flooding.

As you can see bytes total/sec on four 10GbE(screenshot 1) below, it went from 10MB/s to 300MB/s on four links at 3:00am and caused no buffers errors.(screenshot 2)

 

Questions:

l  Do you have any recommendations to solve this issue? Is it useful to increase 10X transmit buffers frames?
