1. Introduction

1.1. About this Product Specification Manual

This Product Specification Manual is applicable for AIT-1 Turbo drive.
This manual provides information about the Sony SDX-450V series Advanced Intelligent Tape Drives which is

necessary to integrate the drives into OEM products. This manual describes the specifications, SCSI Interface,
diagnostics, operation and installation of the Sony AIT-1 Turbo Tape Drives.

The Sony SDX-450V drive uses data compression to achieve high capacity and high transfer rates. Actual capacity
and transfer rate depends on the source file type. The capacity ratings listed in the next subsection are based on a
186 meter tape AIT-1 Turbo cassette. The Sony SDX-450V drive is a high capacity data storage device using
Advanced intelligent tape (AIT) technology. The Sony SDX-450V drive achieves high data integrity through
read-after-write, an additional level of Error Correction Code, and other features.

The Sony SDX-450V drives provide MIC technology that automatically enhance reliability and performance. The
Sony SDX-450V drives provide read and write capability for MIC user data area.

1.2. Introducing the Sony AIT Technology

While magnetic storage technologies continue to push the envelope of recording density and provide higher
capacities and transfer rates every 18 to 24 months, improvements in time to access this data have become very
limited. Since 1990, tape recording densities have increased up to ten fold, while the time to access this data has
increased less than two fold, creating a large mismatch between the amount of stored data and the ability to access
it.

This large “gap” between data access latency and area density has created a dilemma in application development
and limited the potential to implement truly cost-effective tertiary storage solutions. Many applications compensated
for this deficiency by incorporating multiple redundant tape drives, at higher cost, to achieve an acceptable level of
service for their users. Sony’s new Advanced Intelligent Tape design has recognized this need and provided an
innovative approach to solving the data latency problem while increasing capacity and data transfer rates.

Traditional, older tape technologies relied mostly on conventional mechanical means, such as faster search speeds
or an on-tape index to improve access to stored data. While improvements in electronics and magnetics have been
the main enablers of increased capacity and transfer rates, rarely have these same technologies been employed to
significantly improve access to data.

Sony’s Advanced Intelligent Tape (AIT) architecture has deviated from conventional designs and employed
electronic enhancements to significantly improve access to stored data, using a captive, non-volatile memory chip
contained within the magnetic data cartridge. Known as Memory-In-Cassette, or MIC, this memory chip provides a
direct and immediate connection to the tape drive’s on-board processors to enable quick media load, fast access to
user files and provide a wealth of data about the history and current state of the data cartridge.

2.3. Performance Specification

The data capacity, data transfer rate and data reliability specifications this chapter require the media to conform to
the AIT-E Turbo, AIT-1 Turbo and AIT-1 Media Specification and also require the drive and media to remain within
their respective operating and non-operating environmental specifications. The specifications below also assume
that the C3 ECC frame is generated on writing and used as necessary on reading, and further assumes that
read-after-write rewrites are used as necessary on writing.

2.3.1. Data Capacity

The SDX-450V includes a data compression capability. When data compression is enabled the drive capacity can
increase from 2 times to 3 times. The efficiency of the data compression depends on the actual data that is being

2.3.2.1. Sustained Data Transfer Rate to and From the Tape

The sustained transfer rate to and from the tape is 6Mbyte per second with AIT-E Turbo and AIT-1 Turbo cassette ,
4Mbyte per second with AIT-1 cassette. For this sustained rate to be achieved, the drive must be streaming. There
may be some dependency on the host for this to be achieved.

2.3.2.2. Burst Transfer Rate to and From the SCSI Bus

The SDX-450V will transmit and receive data bursts to and from the SCSI bus at a maximum burst rate of 12 Mbyte
per second, using WIDE SCSI asynchronous transfers and 40 Mbyte per second, using WIDE SCSI synchronous
transfers.

2.3.3. Initialize Time

Initialize Time means the period from the time the drive is powered on to the time when the drive is ready and waiting
for a SCSI command such as INQUIRY or TEST UNIT READY. Initialize Time is less than 5 seconds.

The drive will respond with BUSY status until the completion of the Initialize Time. The Initialize Time does not
include the time necessary for drive diagnostics to complete and the drive to become ready for tape insertion.

2.3.4. Load Time

Load Time means the period from the time when the operator inserts a cassette into the drive to the time when the
drive is ready. The data in the below table represents the average time for SDX-450V. The time it may take for

2.3.8. Error Rate

The un-correctable bit error rate is expected to be less than 1 in 10 to the 17th.

2.3.9. Retry Limits on Rewrites

For Read-after-Write error correction, each frame can be rewritten up to a maximum of 63 times giving 64 writes of
the frame. With Repeat Writing, where every group is written a fixed number of times, the upper limit is 5.

2.3.10. Definition of Failure

A failure is defined as any permanent manufacture of the drive that prevents the user from retrieving data from tape.
This includes failure to power up, failure to unload or eject a cassette, or failure to write and read data to and from the
tape, providing that both the drive and tape are being used within specification.

Faults are not considered failures when they are related to operator error mishandling and abuse, system-related
faults (cabling problems unsupported systems, operating software and so on) no trouble found, and transportation
damage.

2.3.11. Mean Time Between Failures

The Mean Time Between Failures (MTBF) for the SDX-450V is 300,000 power-on hours, assuming a duty cycle of
100%, where:

DutyCycle =

Tape

PowerOn Time

otion Time

×100

2.3.12. Mean Time to Repair

The Mean Time To Repair (MTTR) of the SDX-450V is 30 minutes. Since at the field level the entire drive is
considered a Field Replaceable Unit (FRU) the time to replace the drive with a new one is less that 30 minutes.

2.3.13. Component Life

The specified life of the SDX-450V is 5 years average.

2.3.14. Durability

The durability of the components in the SDX-450V will exceed the number of operations listed on the following table:

2.4. Safety

The SDX-450V conforms to the following safety standards:

• UL/cUL (Underwriters Laboratories, Inc.)
UL 60950 3rd Edition/CSA C22.2 No. 60950-00
Safety of Information Technology Equipment.

• TUV
IEC 950 Safety of Information Technology Equipment including
Electrical Business Equipment (First Edition)

• CE Mark

2.4.1. Conditions of Acceptability

The SDX-450V is for use only in equipment where the suitability of the combination has been determined by an
appropriate certification organization (for example, Underwriters Laboratories, Inc. or the Canadian Standards
Association in North America, and the British Standards Institution or Verband Deutscher Elektrotechniker in
Europe). Other considerations include the following:

1. An enclosure must be supplied to limit the operator’s access to live parts, to provide system stability, and to
furnish the drive with the necessary grounding integrity.

2. The necessary voltage supplies must be provided. These supplies are Extra Low Voltage SEC for UL and
CSA, or Safety Extra Low Voltage for BSI, VDE, and so on, of +5V and +12V DC.

2.Specification

2.6. Data Compression

The tape capacity is increased by compressing data prior to writing it to the tape. Data compression is a well
established technology for reducing the number of bits used to represent data in order to improve data transfer rate
as well as reduce the amount of storage space consumed by the data. The compression ratio depends on the source
file type. The SDX-450V uses the ALDC Data Compression algorithm. ALDC is ECMA standard data compression
algorithm. (ECMA-222) The Data Compression control page allows the host computer to enable data compression
and decompression and also configure the way in which the drive responds to compressed/uncompressed data
boundaries on the tape. The AIT-E Turbo, AIT-1 Turbo and AIT-1 Format allows both compressed and
uncompressed data to reside on the same tape.

The Sony SDX-450V has a DIP switch to disable the Data Compression/ Decompression. After power-on reset with
this DIP switch set, both data compression and data decompression are disabled However, a MODE SELECT
command can override the setting of this DIP switch. After power-on reset without this DIP switch set, both data
compression and data decompression are enabled. (See clause 3.1.5)
