To take advantage of this feature, only the initiator must be directly attached to an SSM.
Note
The SCSI flow statistics feature requires the Enterprise Package license installed only on the initiator
switches.
Note
For SCSI flow statistics, the initiator must connect to an SSM on a Cisco MDS switch while the target
can connect to any other switch in the fabric. The SCSI flow initiator and target cannot connect to the
same switch.
