Applies to

  • ONTAP 9
  • ISCSI
  • LACP in use on client

Issue

  • Lower throughput is seen than expected, especially if comparing to another node or cluster, or server
  • Example: nmon shows only one 10 GbE link (p4p2) having a receive value but the other does not (p3p2) for a high read throughput of ~1 GB/s (maxing one of two 10 GbE links)
