Introduction
Fibre Channel Card Dependencies
1-8 UltraNet Edge Storage Router 3000 Version 3.2 Release Notes
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.
