The UltraNet Edge 3000’s implementation of FC/SCSI Tape 
Pipelining differs slightly from similar channel and device extension 
implementations in earlier McDATA products such as the UltraNet 
Storage Director and CHANNELink. These differences are described 
below.

First, the UltraNet Edge 3000 implementation is Fibre Channel based, 
rather than ESCON or SCSI based. This offers the opportunity to take 
advantage of pipelining’s benefits with both the newer native Fibre 
Channel tape drives as well as older SCSI drives, using a SCSI to 
Fibre Channel bridge.

The UltraNet Edge 3000’s FC/SCSI Tape Pipelining implementation 
configures the Fibre Channel port on the UltraNet Edge 3000 as an 
N_port or NL_port, allowing direct connections to Fibre Channel 
F_ports and FL_Ports (Fibre Channel switches) or Fibre Channel 
N_ports or NL_ports (Fibre Channel HBAs). When configured for 
FC/SCSI Tape Pipelining, the UltraNet Edge 3000 will not connect as 
an E_port and will not extend the switch fabric.

Although disk extension is also provided in the UltraNet Storage 
Director and Channelink products, only tape extension will be 
provided in the initial release of this feature on the UltraNet Edge 
3000.

The device attached UltraNet Edge 3000 (initiator) will dynamically 
discover available targets and actively login/logout to those targets. 
The Fibre Channel worldwide name (WWN) and the associated port 
ids of each current logged-in target are forwarded to the associated 
server attached UltraNet Edge 3000 (target). 

The server attached to the UltraNet Edge 3000 will learn via the 
device attached to the UltraNet Edge 3000’s target discovery, what 
remote targets are available.
