ED_TOV in mS

Enter the ED_TOV (ms) value (in milliseconds) in this field. This field specifies the Error Detect Timeout value in milliseconds for the Fibre Channel Switch application. The default value is 5000.

Ar Number

Select the Ar Number from the drop-down menu. This field represents the Autonomous Region Number of the Fibre Channel Switch application. Selectable values are in the range 0 to 255, where 0 is the lowest and 255 is the highest. Zero is the Ar Number default.

BB_Credits

Enter a value for the buffer-to-buffer credits (BB_Credits) in this field. This value represents the number of BB_Credits provided for each physical Fibre Channel port of the Fibre Channel Switch application. Valid enabled values are in the range of 1 to 128. Seven is the default.

Zoning

The Zoning drop-down list displays all available values. Select Port Zoning if your application requires device controller to device controller mapping or if you have a mix of applications on multiple Fibre Channel Switch interfaces within the node. Port Zoning should also be selected if you are running Smartbits across the Fibre Channel switches.

If a server or device is connected to I/O port 1 on an Edge node, it will only be able to see other servers or devices on I/O port 1 on the peer Edge node.

If None is selected from the drop-down list, the server/device visibility will not be restricted by the Edge I/O port.

If a destination node is mapped, the Zoning option on the destination node is automatically set to the same value.

Enable Disk Streaming

Check this box to enable Disk Streaming. Disk Streaming increases performance in networks that have a round trip latency greater than 10 ms. If a Destination I/F ID is configured for the interface, UltraNet
