Appendix A. Specifications

Sony AIT Tape Drive Specifications

The following table summarizes the specifications for Sony AIT drives.

Parameter Specification

Ambient operating temperature

a. The upper limit applies to the drives themselves. The temperature limits for the Spectra 2K library are given in Library Operating

Environment Limits on page 77. Be sure there is adequate air flow around the library at all times.

+41°F to +104°F (+5°C to +40°C)

Storage temperature -40°F to +158°F (-40°C to +70°C)

Operating humidity 20% to 80% non-condensing

MTBF AIT-1 = 200,000 hours @ 100% duty cycle

AIT-2 = 300,000 hours @ 100% duty cycle

AIT-3 = 400,000 hours @ 100% duty cycle

Average file access time AIT-1 = less than 55 seconds

AIT-2 = less than 27 seconds

AIT-3 = less than 27 seconds

Uncorrectable error rate Less than 1 x 10

-17

bits

Sustained transfer rate

b, c

b. This is a per drive value. Total sustained transfer rate for the library depends on the number of drives installed in the library.

c. The sustained transfer rate per drive can increase by an average of 2.6 times the specified value with compression. Compression

thoughput and capacity depends on the type of data.

AIT-1 = 3 MB/sec native

AIT-2 = 6 MB/sec native

AIT-3 = 12 MB/sec native

Burst transfer rate

d. The actual burst data transfer rate is limited by the performance of the SCSI host bus adapter, the SCSI bus interface controller,

and the buffer control hardware of the drive.

AIT-1 = 40 MB/sec Synchronous maximum

AIT-2 = 80 MB/sec Synchronous maximum

AIT-3 = 160 MB/sec Synchronous maximum
