SCSI Flow Manager

</h1>
<a name="wp1171518"> </a><p class="pBody">
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.

</p>
<a name="wp1171519"> </a><p class="pBody">
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.
