Note The SCSI target and initiator must be connected to different SSMs on different switches.
Note For statistics monitoring, the target device is not required to be connected to an SSM.
SCSI Flow Manager
The SCSI flow manager (SFM) resides on a supervisor module and handles the configuration of SCSI
flows, validating them and relaying configuration information to the appropriate SSM. It also handles
any dynamic changes to the status of the SCSI flow due to external events. The SFM registers events
resulting from operations, such as port up or down, VSAN suspension, and zoning that affects the SCSI
flow status, and updates the flow status and configuration accordingly.
The SFM on the initiator communicates to its peer on the target side using Cisco Fabric Services (CFS).
Peer communication allows the initiator SFM to validate target parameters and program information on
the target side.
