External storage tape
This section describes select external storage tape devices supported by the
current iSeries product line.
IBM TotalStorage 358x Ultrium Solutions with LTO Technology
The 358x Ultrium tape family of devices supports the latest
industry standard Linear Tape-Open (LTO) technology. LTO
technology enhances data compression capacity,
performance, and reliability. A powerful open tape
architecture, Ultrium sets the stage for a new generation of
tape storage products expected to surpass current tape
capacity and performance benchmarks while maintaining
the highest data integrity.
Ultrium 1 technology offers:
Cartridge capacity (using Ultrium 1 media)
– 100 GB native capacity
– 200 GB with two to one (2:1) compression
Data transfer rate
– 15 MB/sec native
– 30 MB/sec with 2:1 compression
Ultrium 2 technology offers:
Cartridge capacity (using Ultrium 2 media)
– 200 GB native capacity
– 400 GB with 2:1 compression
Data transfer rate
– 35 MB/sec native
– 70 MB/sec with 2:1 compression
The 3580, 3581, 3582, 3583, and 3584 are connected to IBM Eserver i5 iSeries
servers by fibre channel, low-voltage differential (LVD) Ultra 160 SCSI, or
high-voltage differential (HVD) Ultra Small Computer System Interface (SCSI)
adapters. IBM i5/OS, OS/400, Windows 2000, Windows NT, and other open
systems operating systems are supported.
Note: Compressed data rates are estimates and are data, application, and
processor dependent. User results may vary.
