Switch WWN Proxy

This section provides information about the Fibre Channel Switch World Wide Name Proxy (FCSWWNP) protocol E_port software enhancement.

To accommodate the recent changes Fibre Channel Switch vendors have made to their software to allow for non-security related enhancements, the UltraNet Edge 3000 software has also changed.

Some Fibre Channel Switch software requires its own range of Switch

Names, or World Wide Names (WWN) to be returned in an Exchange

Link Parameter (ELP) response in order to establish a successful

E_port Inter-Switch Link (ISL).

The UltraNet Edge 3000 now has an option in the Fibre Channel configuration file which allows either the FCCNT or the FCXL2 driver to proxy the Switch’s WWN to the remote Edge. This makes the Fibre Channel switches act as if they were communicating with a directly attached switch of the same vendor type. With this option enabled, a successful ISL can be established.

The configuration is done by enabling the Switch WWN Proxy field during the Data Path configuration in UltraNet ConfigManager for E_port extension implementations.

E_Port Disk Streaming Network Recommendations

This section explains the functionality of the performance enhancement feature and provides network recommendations for E_port Disk Streaming.

The main objective of E_port Disk Streaming is to move data more efficiently. E_port Disk Streaming uses a subset of our Fibre Channel Device Extension technology to more efficiently move data in FCP_SCSI applications than our standard E_Port solution.
