xSeries servers. The 358x is connected to the iSeries and AS/400e servers by a High-Voltage
Differential (HVD) Ultra SCSI fast/wide adapters. OS/400, Windows 2000, Windows NT, and
open systems operating systems are supported.
Some advantages of the Ultrium family include:
• Latest Open Standard technology and a strategic IBM platform
• Very cost effective solution for high capacity and fast tape storage
• 3583 and 3584 are modular and expandable solutions with practically unlimited
capacity
• Enables larger-capacity or higher-performance tape backup
• Better alternative product to other externally attached Digital Linear Tape, ¼-inch,
4-mm, or 8-mm tape
• Supports random and auto modes on library models
There are four models of the 358x supported on the iSeries and AS/400e servers as shown in
this table.

iSeries Handbook
Ultrium technology offers a high-capacity, single-reel that offers up
to 200 GB (with 2:1 compression) and 100 GB native
(uncompressed) when using the new ULTRIUM1 media and density.
The actual degree of compression achieved is highly sensitive to the
characteristics of the data being compressed.
Positioning
The 358x family uses Small Computer Systems Interface (SCSI) for
attachment to the iSeries, AS/400e, pSeries, RS/6000 SP, and
