Answer

  • Active IQ Unified Manager reports node statistics based on if the requests processed by a data lif residing on that node.
  • The statistics are considered based on the node that receives the request and not the node that hosts the volume.

 

Example:

  • 2-node cluster
  • A volume that resides on node 2 is accessed via a data lif on node 1.
  • This is considered indirect i/o and the IOPS will be counted for node 1 which received the request rather than node 2 where the volume resides.
