The Built-In AIT has the following specification:
■ Performance
Memory capacity
Bit error rate
Data transfer rate
Burst data transfer speed (SCSI)
Initialize time
Load time
Unload time
Rewind time
• 100 GB (in compression mode: 200 GB)
when using AIT-3 Data Cartridge (tape length: 230 m)
• 50 GB (in compression mode: 100 GB)
when using AIT-2 Data Cartridge (tape length: 230 m)
• 36 GB (in compression mode: 72 GB)
when using AIT-2 Data Cartridge (tape length: 170 m)
• 35 GB (in compression mode: 70 GB)
when using AIT-1 Data Cartridge (tape length: 230 m)
• 25 GB (in compression mode: 50 GB)
when using AIT-1 Data Cartridge (tape length: 170 m)
The value in the compression mode is obtained when the
compression efficiency is 2x.
The compression rate varies depending on the data pattern.
-17
10 or less
• AIT-3, AIT-2: 12 MB/s (in non-compressed mode)
• AIT-1: 8 MB/s (in non-compressed mode)
The data transfer rate varies depending on the server to
which the Built-In AIT is connected.
160 Mbyte/second (max, synchronous)
Depending on your connection environment, it may not be
possible to set 160 Mbyte/seconds.
Less than 5 seconds
Average 14 seconds
Average 21 seconds
when using AIT-1 Data Cartidge (tape length: 170 m)
Average 24 seconds
when using AIT-1 Data Cartridge (tape length: 230 m),
AIT-2 Data Cartridge (tape length: 230 m, 170 m) or AIT-3
Data Cartridge (tape length: 230 m)
Average 105 seconds
when using AIT-1 Data Cartridge (tape length: 230 m),
AIT-2 Data Cartridge (tape length: 230 m, 170 m) or AIT-3
Data Cartridge (tape length: 230 m)
Average 80 seconds
when using AIT-1 Data Cartridge (tape length: 170 m)
If the Built-In AIT is set to perform retries, the times above
may be longer.
