14 About this guide

1 Features and overview
The Sun StorageTek™ SL24 Tape Autoloader and SL48 Tape Library provide compact, high‐capacity,
low‐cost solutions for simple, unattended data backup. This unique design houses up to 12 tape
cartridges for each U of height, with easy access to tape cartridges via removable magazines and one
or more mailslots (see Table 2). Each magazine can hold up to 12 tape cartridges.
The Autoloader and Library are compatible with most operating systems. However, the Autoloader
and Library require either direct support from the operating system or a compatible backup
application to take full advantage of their many features.
The Autoloader and Library are customer expandable with exchangeable tape drives. The Autoloader
and Library support the LTO‐2 HH parallel SCSI tape drive, and the LTO‐3FHSCSIandFibre
Channel tape drives.

Interface specifications and requirements for parallel SCSI
drives
The parallel SCSI Autoloader and Library use the SCSI interface types described in Table 5.The
Autoloader and Library use a separate SCSI ID foreachtapedrive,withdualLUNsonthemaster
driveʹs SCSI ID to control the tape drive (LUN 0) and Library robotic (LUN 1). Sun recommends that
each LTO tape drive be put on its own bus when possible.
Table 5 Parallel SCSI model and interface type
Model SCSI Interface
LTO-2 HH Ultra 160 SCSI LVD/SE
LTO-3 FH Ultra 320 SCSI LVD
The parallel SCSI Autoloader and Library incorporate a wide SCSI‐2orSCSI‐3low‐voltage differential
(LVD) SCSI bus. Make sure your SCSI host adapter or controller supports these standards.
IMPORTANT:
The Autoloader and Library are NOT compatible with a standard differential (Diff) or high‐voltage
differential (HVD) SCSI bus. Do not put the Autoloader or Library on a narrow (50–pin) parallel SCSI bus
because doing so will severely degrade performance.
Parallel SCSI host bus adapters (HBAs)
For optimum performance, place each tape drive on itsownparallelSCSIbuswithahostbusadapter
that can transfer data as fast as the Library can read and write. The HBA must also be supported
by your operating system.
•For LTO‐3 tape drives, use an Ultra 320 HBA.
•For LTO‐2tapedrives,useanUltra3
20 or Ultra 160 HBA.
IMPORTANT:
Do not connect an LTO tape drive to an SE SCSI bus, as it severely degrades Autoloader and Library
performance. A single‐ended SCSI host bus adapter severely degrades Autoloader and Library performance
and limits cable length. Also, if any SE devices are on the SCSI bus, all of the devices on the bus slow
down to SE speed, severely degrading performance.
Multiple LUN support
The Autoloader and Library use a single SCSI ID and two logical unit numbers (LUN). LUN 0 controls
the tape drive and LUN 1 controls the robotic. The Autoloader and Library require an HBA that
supports multiple LUNs. If multiple LUN support is not enabled, the host computer cannot scan
beyond LUN 0 to discover the Autoloader or Library. It just sees the tape drive.
16 Features and overview

RAID controllers, and most on‐board HBAs do not support multiple LUNs.
IMPORTANT:
The Autoloader or Library requires an HBA that supports multiple LUNs, which is also called “LUN
scanning.”
Default SCSI IDs
The default SCSI ID for parallel SCSI tape drivesismanagedbytheAutoloaderorLibrary. The
default SCSI ID for all full‐heighttapedrivesis4.
The default SCSI ID for half‐height tape drives depends on the Library model.
•SL24: The default SCSI ID of the bottom drive bay is 4 and the default SCSI ID of the top
drive bay is 5 as shown in Figure 1.

Interface specifications and requirements for Fibre Channel
drives
The Fibre Channel drive can be connected directly to the server with a host bus adapter (HBA) or
through a storage area network (SAN).
User and service guide 17

If you plan to connect the Autoloader or Library directly to the server, you will need a 2 Gb or 4 Gb
Fibre Channel HBA. A 4 Gb HBA is suitable for all supported drive types. A 1 or 2 Gb HBA might
result in performance degradation when backing up highly compressible data to a 4 Gb tape drive.
In a SAN installation, all switches between the host and the Autoloader or Library must be of the
appropriate type. A 1 or 2 Gb switch in the path may result in performance degradation. Configure
zoning so only the backup servers may access the Library.
Front panel overview
The front panel of the Autoloader or Library provides access to the power button, operator control
panel, left and right magazines, LEDs, and the mailslot as shown in Figure 3 and Figure 4.

be used. Cleaning is only necessary when the device directs you to do so. Additional
cleaning is not necessary.
3. Amber Attention. Illuminated if the device has detected a condition that requires attention by
the operator.
4. Amber Error. Illuminated if an unrecoverable error occurs. A corresponding error message
displays on the LCD screen (see “Troubleshooting” on page 107 for more information).
Back panel overview
The back panel provides access to the drive interface connectors, the tape drives, the power connector,
the Ethernet, serial and USB ports, and the magazine release holes. The Autoloader and Library
support parallel SCSI and Fibre Channel tape drives. For example, Figure 6 showsanSL48witha
full‐height parallel SCSI tape drives and Figure 7 shows an SL24 with a Fibre Channel tape drive.
