Ultrium Tape Drives
This library supports Ultrium 3, Ultrium 4, and Ultrium 5 Tape Drives. Each tape
drive in the library is packaged in a container called a drive sled. The drive sled is
a customer replaceable unit (CRU), and is designed for quick removal and
replacement in the library.
The IBM Ultrium 5 Tape Drive supports the Fibre Channel interface. The IBM
Ultrium 4 Tape Drive supports SAS or Fibre Channel interfaces. The IBM Ultrium
3 Tape Drive supports LVD Ultra160 or Fibre Channel interfaces. Depending on
which drive is installed, it features two HD68 SCSI connectors, two SAS SFF-8088
connectors, or one LC Fibre Channel connector.
Note:
Ultra160 SCSI, SAS, and Fibre Channel drives are allowed in the same
physical and logical libraries. However, you should ensure that the host
application will support a mix of interface drive types.
Speed Matching
To improve system performance, this tape drive uses a technique 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 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 power management function controls the drive's electronics so that part of the
electronics completely turn OFF when circuit functions are not needed for the
drive's operation.
