Fibre Channel Card Dependencies

The UltraNet Edge 3000 supports two types of Fibre Channel cards; FCBB or FCXL2. The FCBB

card is standard, the FCXL2 card is only used for FC/SCSI Tape Pipelining (Device Extension)

implementations.

Table 1-4 explains the configurations that can be run with each card.

FC/SCSI E_port Configurations

An E_port is an expansion port used to link multiple Fibre Channel switches together into a single

fabric.

The UltraNet Edge 3000 offers the standard E_port configuration and E_port Disk Streaming

which moves data more efficiently in high latency networks than our standard E_port solution.

E_port Disk Streaming functions as a subset of our Fibre Channel Device Extension technology. A

significant performance gain is normally achieved in networks which limit the number of

concurrent SCSI I/O operations and also in networks with high latency.

IP and ATM WANs are supported with E_port configurations.
