Multi-Unit Library Systems
The Library features SmartScale Storage™ , 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 ve rtical PTM. Unde r the control of the unit you
configure to be the master unit, the PTM integrates the robotics in the indi vidual slave units into
a single high-performance library robotics system. For more information, see Appendix C,
“Installation.”
The SmartScale Storage architecture gives you a truly scaleable library that can smoothly
expand to mee t 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 mas ter 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 us e the front slot in the tape cartridge magaz ine (the first
slot you see when you open the door) as a mail slot for inserting or removing a single cartrid ge
without interrupting host operations in progress. The mail sl ot i s implemented as the SCSI
IMPORT/EXPORT commands.
SCSI Interface
The unit presents the following to the host:
■ A single SCSI medium changer device with a single SCSI medi um transport element
■ A number of SCSI storage el ements equal t o the total number of cartrid ge magazine slots
■ A single SCSI import/export element
■ A number of SCSI data tra nsfer elements equal to the total number of dr ives in the Libr ary
Multi-Server Data Sharing
A host computer with a SCSI controller connected to a bus is a SCSI initiator. The Li brary 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 s ingle Library over a single SCSI bus.
This allows multiple hosts to operate the library robotic s, loading and unloading cartridges as
each host requires.
In a library syst em 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 drive s
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.
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 Appendix C, “Installation.”
SCSI Bus Performance Considerations
System Description 1-3
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, whic h depends on file content, but
averages approximately 2:1.
Data Transfer Rate
The data tra nsfer rate of the Library depe nds 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)
Each drive has a maximum sust ained rate of 12 MB/s with compressed data. As a result, the
transfer rate of a two-drive unit occupies t he full bandwidth of the bus. Shar ing a SCSI bus
among more than two drives degrades the maximum performance of the library system.
Internal Cabling Configuration
Each SCSI bus i n t he Library is wired separately. The library ro botics 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 uni t to be daisy-c hained to a single SCSI bus. For m ore detailed
information, see Appendi x C, “Installation.”
@ 12 MB/s (compressed)
1-4 Compaq StorageWorks SSL2000 Series LIbrary Maintenance and Service Guide
Bus Length Limitations
A single-ended Fast/Wide SCSI bus is limited i n 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 len gt h, inclu ding
cabling within the units. If all devices and host adapter are LVD, length is limite d t o
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 Par t Number 175199-B21.
Shuttle Lockdown Mechanism
Compaq has installed a shuttle lockdown mechanism as a precautionary safety mechani s m to
prevent damage to the Libr ary during shi pment from the f actory. The mechanism is a springloaded 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 Appendix C, “Installation,” for more information.
