Using the SAN Extension Tuner Wizard

Use the SAN Extension Tuner wizard to perform the these tasks:

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

  1. Select and right-click a valid FC IP link in the Map pane then select SAN Extension Tuner. Or, highlight the link and choose Tools > Other > SAN Extension Tuner. You see the SAN Extension Tuner Wizard.
  2. Select the Ethernet port pairs that correspond to the FCIP link you want to tune and click Next.
  3. Note     The Ethernet ports you select should be listed as down.

  4. Create and activate a new zone to ensure that the virtual N ports are not visible to real initiators in the SAN by clicking Yes to the zone creation dialog box.
  5. Optionally, change the default settings for the transfer data size and the number of concurrent SCSI read and write commands as follows:
    1. Set Transfer Size to the number of bytes that you expect your applications to use over the FCIP link.
    2. Set Read I/0 to the number of concurrent SCSI read commands you expect your applications to generate over the FCIP link.
    3. 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.

    1. Check the Use Pattern File check box and select a file that you want to use to set the data pattern that is generated by the SAN extension tuner.
  6. Click Next.
  7. Click Start to start the tuner. The tuner sends a continuous stream of traffic until you select Stop.
  8. Click Show to see the latest tuning statistics. You can select this while the tuner is running or after you stop it.
