Operations
This chapter describes how StorageTek tape drives operate using a Fibre
Channel (FC) interface.
Note:
This document is defined by the requirements in FC-Tape
Revision 1.17. As updates occur to the FC-Tape document, this
document will be updated accordingly.

Connections
The T10000 tape drives support connections for both:
•
2FC = Direct N_Port, Arbitrated Loop, and a Fabric
•
4FC = Direct N_Port and a Fabric
Arbitrated Loop
An arbitrated loop provides multiple connections for devices that share a single
loop, but only provides point-to-point connections between an initiator and
target during communications.
Note:
Both public loops and private loops are supported.
As with SCSI protocol, when devices want to communicate on the bus, they
must arbitrate and win the connection before communications can begin. The
same goes with the arbitrated loop. Once a device is powered-on and
initialized on the loop, it must arbitrate and win to be able to communicate with
other devices on the loop.
Fabric Attachment
Fabric, or F_Ports, provide “direct” attachments to the tape drives. The Fabric
receives frames from a source N_Port and routes them to a destination N_Port
whose address identifier is specified within the frame.
