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 used
only for FC/SCSI Tape Pipelining (Device Extension)
implementations.
Table 2-7 shows the supported configurations that can be run with
each card.
The Fibre Channel port type can be configured in UltraNet
ConfigManager. Only one Fibre Channel port type is supported in an
individual unit. For example, E_port cannot operate simultaneously
with F_port in the same Edge unit. The port types must also match
from peer to peer. To reconfigure the port type configuration,
reconfigure UCM and reboot the unit.
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
