The SCSI target and initiator must be connected to different SSMs on different switches.

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.
