The adapter speed is also a factor in tape performance. Note that the LTO
Ultrium 2 HVD drives may not see a performance increase over LTO Ultrium 1
HVD drives when attached to #2749 PCI Ultra Magnetic Media Controller.
Installing more than one Ultrium drive on a SCSI bus can impact the save rate of
the device.
The IBM TotalStorage 358x tape devices that are supported on i5 and iSeries
servers include:
IBM TotalStorage Ultrium External Tape Drive 3580
The IBM LTO 3580 tape drive is one
building block of a family of scalable, flexible
tape solutions. By leveraging advanced LTO
technology, the IBM Tape Drive is suited for
handling the backup, save and restore, and
archival data storage needs of a wide range
of small systems.
The IBM LTO Ultrium 2 models of the IBM
TotalStorage Ultrium External Tape Drive
have a capacity of up to 400 GB with
compression (2:1) with the use of the new
IBM TotalStorage LTO Ultrium 200 GB Data Cartridge. IBM Ultrium 2 Tape
Drives can read and write first generation LTO Ultrium Data Cartridges at
original capacities and with improved performance (20MB/sec).
The IBM LTO 3580 Ultrium 2 drive more than doubles tape drive performance
over LTO Ultrium 1 drives with a 35 MB/sec native data transfer rate (70
MB/sec with 2:1 compression). The IBM Ultrium External Tape Drive 3580 is
an excellent alternative to S-DLT, DLT, ¼-inch, 4 mm, or 8 mm tapes drives.
