System Description
Introduction
The Compaq StorageWorks SSL2000 Series is a tape library system that
combines Advanced Intelligent TapeTM (AIT) drive technology with advanced
robotics. Designed for high duty-cycle online and near-online applications,
such as hierarchical storage management, it is a superior performer in
high-volume backup and archival service.
The Compaq StorageWorks SSL2000 Series Library can operate as a
standalone library or can be combined with additional units to form a larger
integrated system.
A Library can be equipped with one or two tape drives and a 20-slot tape
cartridge magazine that includes one mail slot.
This chapter includes descriptions for:
I Library models
I Multi-unit Library systems
I Tape cartridge mail slot
I SCSI interface and bus performance considerations
I Shuttle lockdown mechanism
I Library features
I Advanced design features

Library Models
Libraries are currently available with:
I A tabletop or rackmount version
I One or two tape drives
I An optional Pass-Through Mechanism (PTM) for connecting up to five
library units
I AIT 2 technology
I A Fast/Wide, Low Voltage Differential (LVD)/Single Ended (SE)
SCSI-2 interface
The drives used in the Library read from and write to 8 mm AIT 2 data tape
cartridges with a native capacity of 35 GB or 50 GB (see Table 1-1).

Multi-Unit Library Systems
The Library features SmartScale StorageTM an architecture that lets you
combine multiple units into an integrated library system. This architecture
enables the robotics in each of the Library units to exchange cartridges by
means of a vertical PTM. Under the control of the unit you configure to be the
master unit, the PTM integrates the robotics in the individual slave units into a
single high-performance library robotics system. For more information, see
Chapter 3, "Installing and Removing the Pass-Through Mechanism."

System Description 1-3
The SmartScale Storage architecture gives you a truly scaleable library that
can smoothly expand to meet your growing storage needs. You can start with a
system configured to your present requirements, confident that as your storage
needs evolve, adding units and extending the PTM can easily modify the
Library. Add drives for faster performance or magazine space for greater
capacity, as needed. Then just turn on the power, and immediately the system
updates the system map so the host is informed of the expanded capability.
The SmartScale Storage architecture has built-in redundancy so that if the
master unit fails, a slave unit (slave 0) can be configured to take over as the
master unit. This is done without having to make hardware changes except
moving the motor cable to the new master.
Tape Cartridge Magazine Mail Slot
If your host software permits, you can use the front slot in the tape cartridge
magazine (the first slot you see when you open the door) as a mail slot for
inserting or removing a single cartridge without interrupting host operations in
progress. The mail slot is implemented as the SCSI IMPORT/EXPORT
commands.
SCSI Interface
The unit presents the following to the host:
I A single SCSI medium changer device with a single SCSI medium
transport element
I A number of SCSI storage elements equal to the total number of
cartridge magazine slots
I A single SCSI import/export element
I A number of SCSI data transfer elements equal to the total number of
drives in the library
Multi-Server Data Sharing
A host computer with a SCSI controller connected to a bus is a SCSI initiator.
The Library is a SCSI target. SCSI rules permit multiple initiators on a single
bus. Therefore, with the proper host software, it is possible to connect multiple
hosts to a single Library over a single SCSI bus. This allows multiple hosts to
operate the library robotics, loading and unloading cartridges as each host
requires.

1-4 Compaq StorageWorks SSL2000 Series Library Reference Guide
In a library system with many drives, it might be desirable to use multiple
SCSI buses for the drives so the data transfer rate of the drives is not limited
by bus bandwidth. Individual drives can be connected to separate hosts. Using
special software, one of the hosts can act as a master server, processing all
robotics commands and permitting several hosts to share a common database.

System Description 1-5
SCSI Configuration
The Library standard SCSI interface is a Fast/Wide LVD/SE using
high-density, 68-pin D-series connectors. For more information, see Chapter 2,
"Installation."
SCSI Bus Performance Considerations
Drives
With a standard Fast/Wide SCSI interface, each drive offers a sustained native
data transfer rate of 6 MB/s. In a two-drive unit, the total native rate is twice
these rates. The rates for compressed data are the native rates multiplied by the
compression factor, which depends on file content, but averages
approximately 2:1.
Data Transfer Rate
The data transfer rate of the Library depends on the type of the AIT drive,
number of drives, and the number of drives connected to the SCSI bus. The
library robotics imposes minimal loading on the bus.
AIT-2 Fast/Wide @ 40 MB/s (burst)
AIT-2 Sustained @ 6 MB/s (native)
@ 12 MB/s (compressed)
Each drive has a maximum sustained rate of 12 MB/s with compressed data.
As a result, the transfer rate of a two-drive unit occupies the full bandwidth of
the bus. Sharing a SCSI bus among more than two drives degrades the
maximum performance of the library system.
Internal Cabling Configuration
Each SCSI bus in the Library is wired separately. The library robotics and
drive 1 share one bus; add-on drives are connected to separate SCSI buses.
SCSI jumper cables are available to allow the drives and robotics of a unit to
be daisy-chained to a single SCSI bus. For more detailed information, see
Chapter 2, "Installation."

1-6 Compaq StorageWorks SSL2000 Series Library Reference Guide
Bus Length Limitations
A single-ended Fast/Wide SCSI bus is limited in length to 10 ft (3 m),
including cabling within the units. A differential Fast/Wide SCSI bus can be
up to 82 ft (25 m) in length, including cabling within the units. If all devices
and host adapter are LVD, length is limited to 39 ft (12 m).
Independent SCSI Buses for SE
For those two-drive applications where both AIT drives run in SCSI SE mode
(rather than LVD mode), each drive must be connected to its own SCSI bus.
Physical Configuration
The Library is configured as a tabletop model. To convert a tabletop Library to
a rackmounted model, order the Compaq Conversion Kit, part number
175199-B21.
Shuttle Lockdown Mechanism
Compaq has installed a shuttle lockdown mechanism as a precautionary safety
mechanism to prevent damage to the Library during shipment from the
factory. The mechanism is a spring-loaded screw in the back of the Library
that secures the shuttle to a bracket.
NOTE: You must release the shuttle lockdown mechanism before powering up the unit or
it will not operate. See Chapter 2, "Installation," for more information.

Figure 2-8. Installing the panel extension
2. Install two screws through the holes in the panel extension into the
Library.
NOTE: The panel extension has two pairs of mounting holes. Use the forward pair for the
regular mounting position ( 1 Figure 2-8). Regular mounting leaves the curved front panel
surface extending outward from the front of the storage cabinet. The rear pair of holes
permit a flush mount position that leaves the front panel recessed into the storage cabinet
( 2 Figure 2-8). You might choose flush mounting if, for example, you have storage
cabinet doors that would be hindered by the protruding front panel.
3. Repeat steps 1 and 2 for the other side of the Library.
