To tune the required FC IP link using the SAN Extension Tuner Wizard in Fabric Manager, follow these steps:

- Optionally, change the default settings for the transfer data size and the number of concurrent SCSI read and write commands as follows:
- Set Transfer Size to the number of bytes that you expect your applications to use over the FCIP link.
- Set Read I/0 to the number of concurrent SCSI read commands you expect your applications to generate over the FCIP link.
- Set Write I/0 to the number of concurrent outstanding SCSI write commands you expect your applications to generate over the FCIP link.
Note There is only one outstanding I/O at a time to the virtual N-port that emulates the tape behavior.
- Click Next.
- Click Start to start the tuner. The tuner sends a continuous stream of traffic until you select Stop.
