SAIT
SDLT 600
Parameter Specification
Tape capacity
a
a. Compression thoughput and capacity depend on the type of data.
500 GB native (1.3 TB compressed)
MTBF 300,000 hours at 100% duty cycle
Average file access time 45 seconds
Uncorrectable error rate Less than 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.
30 MB/sec native (78 MB/sec compressed)
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 drive’s buffer control hardware.
160 MB/sec synchronous maximum
Power consumption 29 watts typical (50 watts maximum)
