Dell PowerVault TL1000 - Manual (Page 26)

Ultrium tape drives
The TL1000 Tape Autoloader supports the Ultrium 4 (S4H), Ultrium 5 (S5H), and
Ultrium 6 (S6H) half-high tape drives.
The Ultrium 4, Ultrium 5, and Ultrium 6 half-high tape drives support the Serial
Attached SCSI (SAS) interface. They have one Mini-SAS (SFF-8088) connector.
Speed matching
To improve system performance, the Ultrium 4, Ultrium 5, and Ultrium 6 Tape
Drives use a technique that is called speed matching to dynamically adjust its
native (uncompressed) data rate to the slower data rate of the attached server.
Channel calibration
The channel calibration feature of the Ultrium 4, Ultrium 5, and Ultrium 6 Tape
Drives customizes each read/write data channel for optimum performance. The
customization enables compensation for variations in the recording channel
transfer function, media characteristics, and read/write head characteristics.
Power management
The Ultrium 4, Ultrium 5, and Ultrium 6 Tape Drives feature a power management
function. This function controls the drive’s electronics so that part of the electronics
completely turns OFF when circuit functions are not needed for the drive’s
operation.
Media
The TL1000 Tape Autoloader uses Ultrium tape cartridges that provide up to
2500-GB native capacity (up to 6250 GB with 2.5:1 hardware data compression) for
Ultrium 6 tape drives, 1500-GB native capacity (up to 3000 GB with 2:1 hardware
data compression) for Ultrium 5 tape drives, and 800-GB native capacity (up to
1600 GB with 2:1 hardware data compression) for Ultrium 4 tape drives.
