Drive Performance
If you run applications that are highly dependent on tape-processing speed, take
advantage of the significant performance improvements provided by this tape
drive.
Table 1-1. Performance characteristics
Performance Characteristics
TS2250 Tape Drive
Native data rate
140 MB/s (with Ultrium 5 media)
Maximum sustained data rate (at maximum compression)
550 MB/s
Burst data rate
600MB/s
Nominal load-to-ready time
12 seconds
Nominal unload time
17 seconds
Average rewind time
75 seconds
Note:
All sustained data rates are dependent on the capabilities of the interconnect.
By using the built-in data-compression capability of the tape drive, greater data
rates than the native data transfer rate can be achieved. However, the actual
throughput is a function of many components, such as the host system processor,
disk data rate, block size, data compression ratio, SAS bus capabilities, and system
or application software.
Cartridge compatibility
The TS2250 uses the IBM LTO Ultrium 1500 GB Data Cartridge and is compatible
with the cartridges of its predecessor, the IBM TS2240 Tape Drive. The drive
performs the following functions:
v
Reads and writes Generation 5 and Generation 4
v
Only reads Generation 3 cartridges
