For FC420 installation steps, refer to the FC420 Fibre Channel Bridge Quick Reference Guide (PN T6473054). For a description of M-Series library operating procedures, see the Tandberg Data M-Series Library User's Guide (PN T6423045). Fibre Channel Overview 0 The M2500 library is controlled by a host computer via a SCSI differential bus using the SCSI-2 medium changer command set. The library's architecture allows for easy conversion from the SCSI host interface to a Fibre Channel host interface by installing the FC420 Bridge option. Fibre Channel is a serial data transfer architecture for use with computers and mass storage devices. Fibre Channel is rapidly emerging to challenge SCSI as the interface of choice for host-tostorage applications. Fibre Channel advantages include: · · · · Connection distances of up to 500 meters Up to 2 GB/sec data transfer rates with Autonegotiate Support for up to 126 devices on a loop Support for 24-bit addressing for over 16 million devices in point-to-point mode or fabric, when using a Fibre Channel switch or multiple Fibre Channel switches. Operating system independence Interconnect flexibility Fibre Channel fabric switches provide full direct connectivity between all ports on a network, which can increase the total throughput of all devices on a network. · · · Library Operation After FC420 Bridge Installation 0 Once the FC420 Bridge SCSI to Fibre Channel option is installed and tested, the library operates exactly as a library with a SCSI host interface. User operation of the library via the graphical user interface (GUI) panel is unchanged. Introduction 3 Tandberg Data FC420 Bridge Option User's Guide Document T6423053-01, Ver. 1, Rel. 0 November 2002 Cabling the M2500 Library for Fibre Channel The cabling configuration used for the M2500 library with the FC420 option depends on the following factors: · · · · Number of tape drives installed Tape drive type (SDLT or LTO) Number of FC420 Fibre bridges installed Data transfer rate of the storage area network (SAN) 0 One- and Two-Drive Library Cabling 0 If the M2500 library has only one or two tape drives, the cabling is the same regardless of drive type or SAN. One- or two-drive libraries only require one FC420 Fibre bridge. Figure 1 shows the cabling for a one-drive library. Figure 1 One-Drive Cabling M2500 FC420 SCSI SCSI controller SCSI Drive 1 Primary electronics module Fibre Auxiliary electronics module Slot for FC420 Terminator Slot for FC420 SAN As shown in the figure, a SCSI daisy chain is established from one of the SCSI ports on the FC420 to the SCSI controller and then to drive 0, where the daisy chain is terminated. The SCSI controller is included in the chain to pass SCSI commands to the robot. The SCSI controller and drive 1 must be on the same SCSI bus because the SCSI controller has termination disabled. 4 Cabling the M2500 Library for Fibre Channel Tandberg Data FC420 Bridge Option User's Guide Document T6423053-01, Ver. 1, Rel. 0 November 2002 Figure 2 shows typical cabling for a two-drive library. Figure 2 Two-drive Cabling M2500 SCSI FC420 SCSI SCSI controller SCSI Drive 2 Drive 1 Primary electronics module Fibre Auxiliary electronics module Slot for FC420 Terminator Slot for FC420 SAN In a two-drive library, the second drive (Drive 2) should be connected to the available FC420 SCSI port, creating a second SCSI bus. This fully utilizes the FC420 Fibre bridge and maximizes the communication bandwidth available to each tape drive. Cabling with Three or More Drives 0 When cabling M2500 libraries with three or more tape drives, you need to know the type of tape drive installed in the library and the data transfer rate of the SAN to determine the correct SCSI configuration. Note: As with the one- and two-drive configurations, all Fibre-toSCSI cabling configurations must include the SCSI controller so that SCSI commands intended for the robot are successfully communicated. Cabling the M2500 Library for Fibre Channel 5 Tandberg Data FC420 Bridge Option User's Guide Document T6423053-01, Ver. 1, Rel. 0 November 2002 SDLT/LTO Drive Cabling with a 1-GB SAN 0 For example, if you have SDLT or LTO drives and a 1 GB SAN, Quantum recommends a ratio of one tape drive per FC420 SCSI port. This means that three- and four-drive libraries would require a second FC420 Fibre bridge, and five- and six-drive libraries would require three FC420 bridges, as shown in Figure 3. Note: SDLT and LTO tape drives are sometimes referred to as Superdrives. Figure 3 One-Drive-PerFC420-Port Cabling M2500 SCSI FC420 SCSI SCSI controller SCSI Drive 2 Auxiliary electronics module SCSI FC420 Drive 4 SCSI Drive 1 Primary electronics module Fibre Drive 3 SCSI FC420 Drive 6 Drive 5 Terminator SCSI Fibre Fibre 1-GB SAN SDLT/LTO Drive Cabling with a 2-GB SAN 0 If the M2500 library with SDLT or LTO drives is connected to a 2-GB SAN, Tandberg Data recommends a maximum ratio of 2 tape drives per FC420 SCSI port. This means that one FC420 Fibre bridge could manage up to four tape drives, but a second FC420 Fibre bridge would be required for libraries with five or six tape drives. 6 Cabling the M2500 Library for Fibre Channel Tandberg Data FC420 Bridge Option User's Guide Document T6423053-01, Ver. 1, Rel. 0 November 2002 Figure 4 shows a six-drive library utilizing a two-drive per port cabling scheme. Note: To increase the bandwidth available to each tape drive, install additional FC420 Fibre bridges and use the cabling configuration shown in figure 3.

The key to successfully configuring the FC420 Fibre bridge is to: · Know exactly how the SCSI cabling in the library is configured including: · · · · How many FC420 Fibre bridges are present in the library. How many SCSI buses are present in the library. How many SCSI devices are connected to each bus. This was established in the previous section of this document. 0 Use the FC420 Bridge Services software to create a Map file identifying which SCSI devices are electrically connected to which Fibre Channel ports on the FC420 board. Setting Up an Ethernet Connection Verifying Current FC420 Firmware on page 10 Setting Local Echo Mode on page 10 Scanning the SCSI buses on the Library on page 10 Creating a Map File for the FC420 on page 11 These major steps must be repeated for each FC420 Fibre bridge in the library. The major steps for configuring FC420 Fibre bridge firmware involve: · · · · · Note: Setting Up an Ethernet Connection 0 To set up an Ethernet connection between the FC420 Fibre bridge and a service PC or other stand-alone computer: 1 Establish a physical connection between the FC420 bridge and the computer using a CAT 5E crossover cable. To do this: a b c Make sure the computer and library are both turned off. Attach one end of the cable to the RJ-45 connector at the bottom of the FC420 bracket.

The software uses a Command Line Interface (CLI) that is usable with any PC and a terminal emulation program such as HyperTerminal or ProComm. FC420 Service Software Operation 0 The Command Line Interface provides access to the FC420 services through a set of ASCII-based command lines. Commands have four types of operation: · · · Immediate--cause an immediate action; not preceded by a get or set operation. Get--returns the current value of a parameter or setting. This command may be abbreviated to "g." Set--changes the value of a parameter or setting. This command may be abbreviated "s," and does not take effect until a SaveConfiguration command is sent. Usage--if the form of an operation cannot be determined, it is assumed to be the "Usage" form and a brief help message is displayed. · The commands are not case sensitive. Decimal numbers may be entered as raw numerical input, such as 123. Octal numbers must be preceded by the number 0, for example 0713. Hexadecimal numbers must be preceded by the C-style of 0x prefix, such as 9x1FA4. Quoted strings are treated as a single parameter for any command which expects character input, regardless of space in the string. Several non-immediate commands require a SaveConfiguration before their modified parameters take effect. When such a command is executed an asterisk appears next to the command line prompt.
