DLT-S4 Product Manual 54 Chapter 7 7Fibre Channel Interface This chapter provides Fibre Channel interface specifications associated with the DLT-S4 tape drive, which include the following topics: · Rear Panel Connectors · Fibre Channel Cable Connector · Fibre Channel Tape Drive Features · Practical Considerations · Fibre Channel Speed and Topology · World-wide Names The Fibre Channel interface operates at transfer rates up to 4 Gb/second. The Fibre Channel interface is ONLY available with the internal and library models; it is not available with the tabletop model. Longwave transceivers (with fiber optic cable) support distances up to 10 kilometers; short pulsewave transceivers (with fiber optic cable) support distances up to 500 meters. For more information on transfer rates and protocol options, see table 4 on page 11. For more information on the Fibre Channel interface, see the DLT-S4 Interface Reference Guide (81-81281-xx). Also, see the latest Fibre Channel reference documentation available at www. t10. org.

The Fibre Channel cable connector looks like the one shown in figure 18. 7 DLT-S4 Product Manual 56 Chapter 7 Fibre Channel Interface Fibre Channel Tape Drive Features Figure 18 Fibre Channel Cable Connector Fibre Channel Tape Drive Features The DLT-S4 Fibre Channel tape drive supports the following features: · Automatic speed negotiation, with transfer rates of: · · · 1 Gb per second 2 Gb per second 4 Gb per second 7 · Automatic topology negotiation (the tape drive operates as an NL_Port or N_Port): · · · · Arbitrated Loop--private loop, NL_Port to NL_Ports(s) Arbitrated Loop--public loop, NL_Port to NL_Ports(s) and one FL_Port. Fabric attachment--N_Port to F_Port Point-to-Point attachment--N_Port to N_Port · FCP-2 (SCSI-3 command set) for tape devices · Class 3 level of service · Basic and extended link services · Hard assigned port address, when attached to a library. The library has the ability to assign a hard address to the tape drive. If no hard address is assigned to the tape drive, then a soft address is taken initially. DLT-S4 Product Manual 57 Chapter 7 Fibre Channel Interface Practical Considerations Practical Considerations This section describes considerations specific to the DLT-S4 Fibre Channel tape drive. 7 Hot-Swappable Cables 7 Fibre Channel cables are "hot swappable, " which means that you may connect and disconnect them with unit power turned on. Therefore, unlike some other systems, the tape drive and computer may remain powered on while you connect the DLT-S4 tape drive to the host computer. Power Usage 7 DLT-S4 Fibre Channel tape drives use slightly more power than SCSI- configured tape drives. See the DLT-S4 Product Specification (81-81279-xx). Power Cycle (Tape Drive On) 7 When the tape drive completes the power cycle process (including POST) and the port is initialized, the Fibre Channel port is enabled and will attempt to initialize on the attached Fibre Channel topology. When the tape drive completes the power cycle process (tape drive turned on and POST complete), the device is on-line and capable of tape drive operations. See Power-On Self-Test on page 113 for information about POST. Failure to Obtain a Loop Address 7 If the tape drive is unable to obtain an address (fabric assigned, previously assigned, hard assigned, or soft assigned), it goes into a nonparticipating mode and immediately implicitly logs out all logged-in ports. If the tape drive experiences a power-on reset, or recognizes an LIP (AL_PD, AL_PS), it does not retain a previously acquired address to use during the next loop initialization. DLT-S4 Product Manual 58 Chapter 7 Fibre Channel Interface Fibre Channel Speed and Topology Fibre Channel Speed and Topology 7 Although Fibre Channel DLT-S4 tape drives will auto-negotiate the speed and topology, you may override the automatic selections by placing jumpers on the Fibre Channel jumper block at the rear of the tape drive. If you decide it is necessary to change the tape drive's speed or topology, use your fingers to move the jumpers to the pattern corresponding to the speed or topology you want. Using this jumper block is optional. Note: The tape drive only checks the jumpers at a power cycle. To change the speed or topology configurations after installation, turn off the tape drive, move the jumpers as needed, and then turn on the tape drive. See: · Figure 17 for the Fibre Channel jumper block location · Figure 19 for the empty jumper block that you use to set the speed and topology · Table 32 and table 33 for the various jumper setting combinations Figure 19 Fibre Channel Speed and Topology Jumper Block DLT-S4 Product Manual 59 Chapter 7 Fibre Channel Interface Fibre Channel Speed and Topology Table 32 Fibre Channel Speed Configuration To Select This Speed 1 Gb per second 2 Gb per second 4 Gb per second Auto-negotiate Put Jumper on These Pins 7 and 8 5 and 6 3 and 4 No jumpers Result Tape drive attempts to synchronize the link at 1 Gb per second only Tape drive attempts to synchronize the link at 2 Gb per second only Tape drive attempts to synchronize the link at 4 Gb per second only Auto Speed Negotiate: Tape drive attempts to synchronize · first at 4 Gb per second · then at 2 Gb per second · then at 1 Gb per second 5 and 6 AND 3 and 4 Auto Speed Negotiate: Tape drive attempts to synchronize · first at 4 Gb per second · then at 2 Gb per second · then at 1 Gb per second Note: Pins 1 and 2 are spare pins that are not used; there is no effect if they are jumpered or not jumpered.

World-wide Names 7 Each DLT-S4 tape drive contains two unique, 64-bit world-wide names: a node name for the tape drive, and one for the tape drive's Fibre Channel port. The tape drive reports the world-wide names to the host through the INQUIRY Command (12h). [. . . ] (See Native Capacity. ) Node In referring to a Fibre Channel network, a node is any device attached to the network. P PAB Pre-amplifier Board Parity A method of generating redundant information that can be used to detect errors in stored or transmitted data. PCBA Printed Circuit Board Assembly Peripheral A device added to a system as a complement to the basic central processing unit (CPU), such as a disk drive, tape drive, or printer. Port In referring to a Fibre Channel network, a port connects a node to the network. DLT-S4 Product Manual 149 Glossary Positive Engagement Buckling Mechanism A highly robust, solidly engineered media leader-buckling mechanism for heavy-duty-cycle automated environments. When power is applied to the tape drive, it performs a POST. again. Power Cycle The act of turning the tape drive or system off, then on PRML Partial Response Maximum Likelihood is a method for converting the weak analog signal from the head of a magnetic disk drive into a digital signal.
