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.

When an UltraNet Edge 3000 is configured for E_port, its peer UltraNet 
Edge 3000 must also be configured as E_port.

F_port is a port in the fabric where an N_port can attach. F_ports are frame 
routing ports, which are insensitive to higher level protocols. A port 
configured for F_port can only connect to another N_port via a 
point-to-point connection.

The UltraNet Edge 3000 contains an application which acts as a Fibre 
Channel switch (FCSW) and eliminates the need for an external Fibre 
Channel switch. When the UltraNet Edge 3000 is configured for use 
with the FCSW application, it is configured for F_port.

The UltraNet Edge 3000 offers the standard F_port configuration and 
F_port Disk Streaming which moves data more efficiently in high 
latency networks than our standard F_port solution. F_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, ATM, or SONET (POS) WANs are supported with F_port 
configurations.

When an UltraNet Edge 3000 is configured for F_port, its peer 
UltraNet Edge 3000 must also be configured as F_port.

N_port is a node port, or a port on a disk or computer. Ports that are 
N_port can only communicate with another N_port on another node, 
or to a switch. NL_port is a Node Loop Port; a port supporting the 
Arbitrated Loop protocol.

When running FC/SCSI Tape Pipelining (Device Extension) on the 
UltraNet Edge 3000, it will be configured for N_port or NL_port. For 
more information, refer to 

 in this 

guide.

When an UltraNet Edge 3000 is configured for N_port, its peer 
UltraNet Edge 3000 must also be configured as N_port.
