Product Overview
Oracle’s StorageTek SL150 Modular Tape Library System is a rack-mounted,
automated tape library containing up to 300 tape cartridges (tapes) with 1 to 20 half-
height LTO Ultrium Fibre Channel (FC) or Serial Attached SCSI (SAS) tape drives.
Tape drive bridging provides the external interface for library control. The robot
control is a SCSI Medium Changer device that appears as LUN 1 on a tape drive.
An SL150 is scalable from one to ten modules. A module has two tape drive slots.
Each module stores up to 30 tapes in two 15-slot magazines (one on the left side and
the other on the right side). Additionally, a four slot mailslot is available in the base
module for entering tapes into or removing tapes from the library (see FIGURE 1-1).

Modules
12 SL150 Systems Assurance July2012
Modules
The SL150 Modular Tape Library is comprised of two types of modules: the base
module (designated Module 1) and the expansion module (designated as Modules 2
through 10).
The base module is the smallest fully functional library. The base module contains:
the front control panel, two 15-slot tape magazines (left and right), a mailslot, one
robotic hand, a power supply (with an option to add a second power supply), one
tape drive (with an option to add a second drive), and the robotics. Up to three tape
slots in the base module can be designated as reserved slots to store diagnostic or
cleaning tapes. The bridge drive must reside in the base module.
At the rear of the base module there is an Ethernet port for remote management and
nine USB Type A ports for connection to expansion modules (see FIGURE 1-2).

2. Expansion Module (Module 2 and Module 3)
3. Robot Lock
4. Tape Drive Tray
5. Power Supply
6. Module Controller (Module 2 and Module 3)
An expansion module can be added to the bottom of the library to provide additional
tape cartridge capacity and additional performance by adding tape drives (see
FIGURE 1-1 on page 11). An expansion module requires 2U of rack space. An
expansion module ships with two 15-slot tape magazines (left and right), a module
controller, and an expansion cable. The module controller is connected to the base
module by an expansion cable that incorporates USB Type A connectors. The cable
provides a communication path between the base and expansion modules and a
power source for the module controller.
The module has slots for two tape drives and two power supplies. There is
insufficient power from the expansion cable to support a tape drive. Therefore, a
power supply is required when the expansion module has a tape drive.

Robot
July 2012 Product Overview 13
Robot
The robotic mechanisms reside in the base module. The bull wheel is located in the
top of the base module. The Z platform cables go through pulleys and wind around
the bull wheel. As the bull wheel rotates, the cables lower and raise the Z platform. A
hand assembly moves along Z platform rods to provide the track motion. The hand
assembly contains a retractable reach mechanism, and the hand rotates to align with
the left magazine, right magazine, or a tape drive at the rear of the library. The reach
mechanism has a pair of spring-loaded grippers that grip and release a tape
cartridge.

6. Z Motor
Vision
The hand assembly uses two vertical cavity surface emitting laser (VCSEL) devices to
scan barcodes and to target cells. One VCSEL is mounted on each end of the hand.
Moving the VCSEL past a bar code or the edge of a tape cartridge slot generates a
data stream which is decoded on the main processor to generate the bar code or to
locate a target position.

Class 1 Laser Product Notice
14 SL150 Systems Assurance July2012
Class 1 Laser Product Notice
The StorageTek SL150 Modular Tape Library System contains a class-1 laser as
defined by IEC 60825-1 Ed. 2 (2007).
Human Interfaces
There are three ways to interact with the SL150 Modular Tape Library: the operator
panel, mailslot, and remote interface.
• The front control panel (see FIGURE 1-1 on page 11) contains a 7-inch LCD touch
screen operator panel is an information point rather than as a maintenance tool
(see FIGURE 1-4). Information shown on the panel is primarily in tabular format
and is available for: the library, modules, magazines, the mailslot, partitions (if
enabled), drives, tapes, and settings. The masthead displays the library health
(Operational in this example) and the library state.
FIGURE 1-4 Operator Panel Home Screen
• The four cartridge mailslot, located above the right magazine in the base module,
is used for entering tapes into and removing tapes from the library without
interfering with robot operations. It can be opened from the front control panel
touch screen or from the remote interface depending on your user role.
• The remote GUI is the primary management interface for the SL150, and it is
accessed by entering the library hostname or IP address into a web browser (such
as Firefox, Google Chrome, or Safari). The interface example (shown in
FIGURE 1-5 on page 15) is for a partitioned library, and provides menus for the
library, partitions, drives, tapes, settings, and service.
The library information is presented as a graphical representation of tape slots in
the left and right magazines, mailslots, drives, the robot, and all installed modules
(Module 1 is expanded in FIGURE 1-5 on page 15) while Module 2 is collapsed. In
addition, the slot identification information is shown for right magazine, first row,
and first column. For additional information on slot identification see
Appendix A, “Locations” and Appendix B, “Partitioning Overview”.

SNMP
July 2012 Product Overview 15
The Library control beside the Help icon provides the capability to display library
properties, audit the library, run a self test, expand all available modules, or
collapse all modules.
The partitions, drives, tapes, settings, and service menus present information in a
tabular format. Some of the menus have tabs to present information in distinct
categories. For example, the Settings menu for the administrator role contains the
following tabs: Library, Partitions, Drive Port Settings, Network, SNMP, and User.
An administrator creates individual user accounts for the library and assigns a
distinct user role to each account. The library recognizes four user roles: viewer,
operator, service, and administrator. Each of these roles has limits on what screens
are seen and what actions can be performed.
Refer to the StorageTek SL150 Modular Tape Library System User’s Guide or the Help
system of the remote interface for specific information regarding the user
interface.

SNMP
The library’s SNMP agent can automatically send traps that alert network
management stations of faults and configuration changes. Both version 2c and
version 3 of the SNMP standard are supported.
• Version 2c is backward compatible with earlier versions of the standard, but it is
not secure because authentication credentials (community strings) and
management data are exchanged in clear text.

Partitions
16 SL150 Systems Assurance July2012
• SNMP version 3 is not backwards compatible, but it supports a more secure
authentication method and can encrypt management data.
The administrator defines SNMP users and recipients in the SNMP tab of the Settings
section of the remote GUI. The MIB can be downloaded using the management
interface. Refer to the StorageTek SL150 Modular Tape Library System User’s Guide or the
Help system of the remote interface for specific information.
Partitions
The SL150 Modular Tape Library can be divided into a maximum of two partitions
with each having at least one tape drive and one magazine. Each partition behaves as
an independent library, but all partitions share the use of the reserved cells, the single
robot, and the mailslot. When ejecting cartridges, the mailslot must be explicitly
assigned to a partition before any cartridge movement takes place. The user must
specify the destination partition when entering cartridges through the mailslot.
Note – The administrator can enable partitions from the Settings
section of the remote management interface. Additional
information is available in the user’s guide or the online Help for
the remote GUI.

Planning
This chapter provides information for consideration when planning for the
installation of the StorageTek SL150 Modular Tape Library System.
Multiple LUN Support
The SL150 Modular Tape Library uses a single SCSI ID and two logical unit numbers
(LUN). LUN 0 controls the tape drive and LUN 1 controls the robotics. The tape
drives in the base module provide the bridging function and must be connected to an
HBA supporting multiple LUNs (also referred to as LUN scanning).
SAN Connection
The library can be connected to the host HBA through a storage area network (SAN).
Configure zoning on the Fibre Channel switch so only the backup servers access the
library.
The half-height FC tape drive has an 8 Gb/s data interface.
Serial Attached SCSI (SAS)
SAS uses serial connections, with a direct connection between the host server and
each of the storage devices. SAS signal rates require clean connections and a
minimum number of connections between the HBA and the SL150 Library. Oracle
recommends a maximum SAS cable length of six meters.
The half-height SAS tape drive has a 6 Gb/s data interface.
Oracle SAS HBAs:
3Gb (SAS-1):
• SG-XPCI8SAS-E-Z
• SG-XPCIE8SAS-E-Z
• SG-XPCIE8SAS-EB-Z
6Gb (SAS-2):
•SGX-SAS6-EXT-Z

Drives With Two Ports
20 SL150 Systems Assurance July2012
• SGX-SAS6-EM-Z
SAS-2 Configuration Issues
The Solaris 10 Update 8 and later SAS driver disrupts communications between
Oracle Solaris and common tape backup applications. The SAS driver only allows
one device driver to attach per device (sg, sgen, st, and so forth). Users must have
every component in the following list to be affected:
• Oracle Solaris 10 Update 8 or later or Solaris 11
•AnySAS-2HBA
• Tape drives or libraries using a SAS-2 connection
• A backup application that requires multiple SAS drivers. The most common
backup applications that use multiple device drivers include:
• CA ARCserve
•EMCNetworker
• HP Data Protector
• IBM Tivoli Storage
• Symantec NetBackup
A SAS tape drive attached through the SAS-2 HBA will work on the Solaris system
using just the Solaris native commands such as dd or tar.
Drives With Two Ports
When a tape drive has two ports, host applications can treat the second drive port as
a failover port. The library may report a Check Condition to a command received on
one port when the other port is busy with a library command. When a host
application receives either of the following new Check Conditions, it should reissue
the command:
•NotReady,LogicalUnit Offline (02/04/12h)
• Aborted Command, Logical Unit Communication Failure (OBh/08/00)
Note – The half-height SAS tape drive has two ports while the
half-height FC tape drive has one port.
Note – Only some host applications support this feature. Be sure
to check the status of this feature with your application.
Tape Drive Cleaning
LTO drives send a cleaning request to the SL150 and the host application managing
the library (or partition). You can handle cleaning in either of two ways:
• Automatically manage cleaning by configuring the host application (for example,
Symantec NetBackup or IBM Tivoli Storage Manager) for Automatic, Ta pe A lert, or
reactive cleaning depending on the application.
