Sony AIT Tape Drive Specifications
The following table summarizes the specifications for Sony AIT drives.
Parameter Specification
Ambient operating temperature
a
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
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
