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.
Modules 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.
Robot 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.
Class 1 Laser Product Notice 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.
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.
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.

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).
Drives With Two Ports • 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: •...

Partitioning Overview The SL150 library can be partitioned into two distinct sections. Briefly stated, this means that instead of one library—with all its cartridge slots, tape drives, and mailslots—being a single entity, the library and these components can now be divided into two sections or partitions. Each partition can be accessed by one host or multiple hosts.
Page 34
Partitioning—Feature • Each partition designates tape drives solely to its partition, the other partition cannot use these tape drives. • Partition users must anticipate how much storage area is needed for their resident tape volumes and the amount of free slots required. Once storage needs are defined for the two partitions within the library, sufficient modules need to be present within the library to accommodate this need.
Partitioning—Feature Partitioning—Access Control All hosts that issues commands to a bridged HP LTO-5 drive may also send commands to the library partition. Commands are processed by the partition in which the bridged drive resides. The host sends commands to the drive on LUN 0 and to the library on LUN 1.
Partitioning—Feature FIGURE B-1 Partitioned SL150 Library (Continued) 7. Mailslots 8. Left magazine front 9. Right magazine front 10. Module 10 (Expansion) 11. Partition 1 resource 12. Partition 2 resource 13. Shared resource 14. Reserved slots (configurable, shared resource) Partitioning—Shared Mailslot Behavior When the library is partitioned, the mailslots are shared between the two partitions.
Partitioning—Feature TABLE B-1 shows how the SCSI Move and SCSI Read Element Status commands are affected by the shared mailslot assignment.

Controlling Contaminants Environmental Contaminants Control over contaminant levels in a computer room is extremely important because tape libraries, tape drives, and tape media are subject to damage from airborne particulates. Most particles smaller than ten microns are not visible to the naked eye under most conditions, but these particles can be the most damaging.
Contaminant Properties and Sources numbers, and can easily circumvent many sensitive components’ internal air filtration systems. When computer hardware is exposed to these submicron particles in great numbers they endanger system reliability by posing a threat to moving parts, sensitive contacts and component corrosion. Excessive concentrations of certain gasses can also accelerate corrosion and cause failure in electronic components.
Contaminant Properties and Sources Submicron particulates are much more dangerous to sensitive computer hardware, because they remain airborne for a much longer period of time, and they are more apt to bypass filters. Operator Activity Human movement within the computer space is probably the single greatest source of contamination in an otherwise clean computer room.
Contaminant Effects Cleaning Activity Inappropriate cleaning practices can also degrade the environment. Many chemicals used in normal or “office” cleaning applications can damage sensitive computer equipment. Potentially hazardous chemicals outlined in the “Cleaning Procedures and Equipment” section should be avoided. Out-gassing from these products or direct contact with hardware components can cause failure.
Room Conditions Shorts Conductive pathways can arise through the accumulation of particles on circuit boards or other components. Many types of particulate are not inherently conductive, but can absorb significant quantities of water in high-moisture environments. Problems caused by electrically conductive particles can range from intermittent malfunctioning to actual damage to components and operational failures.
Exposure Points Unsealed concrete, masonry or other similar materials are subject to continued degradation. The sealants and hardeners normally used during construction are often designed to protect the deck against heavy traffic, or to prepare the deck for the application of flooring materials, and are not meant for the interior surfaces of a supply air plenum.
Filtration • Automatic doors should be avoided in areas where they can be accidentally triggered. An alternate means of control would be to remotely locate a door trigger so that personnel pushing carts can open the doors easily. In highly sensitive areas, or where the data center is exposed to undesirable conditions, it may be advisable to design and install personnel traps.
Positive Pressurization and Ventilation Low efficiency filters are almost totally ineffective at removing sub-micron particulates from the air. It is also important that the filters used are properly sized for the air handlers. Gaps around the filter panels can allow air to bypass the filter as it passes through the air conditioner.
Cleaning Procedures and Equipment overall commitment to excellence and quality. An effective cleaning schedule must consist of specially designed short-term and long-term actions. These can be summarized as follows: Frequency Task Daily Actions Rubbish removal Weekly Actions Access floor maintenance (vacuum and damp mop) Quarterly Actions Hardware decontamination Room surface decontamination...
Cleaning Procedures and Equipment Quarterly Tasks The quarterly statement of work involves a much more detailed and comprehensive decontamination schedule and should only be conducted by experienced computer room contamination-control professionals. These actions should be performed three to four times per year, based on the levels of activity and contamination present. All room surfaces should be thoroughly decontaminated including cupboards, ledges, racks, shelves and support equipment.
Activity and Processes work and cleaned with a damp sponge as well. Any unusual conditions, such as damaged floor suspension, floor tiles, cables and surfaces, within the floor void should be noted and reported. Activity and Processes Isolation of the data center is an integral factor in maintaining appropriate conditions.
