In order to take full advantage of modern operating systems, high performance computer
systems are needed. When assessing the performance of a computer system, the aspects
speed and security of the mass-storage subsystem are gaining increasing importance. As a
result of the constantly growing acceptance of the RAID technology (Redundant Array of
Inexpensive Disks) in these computer systems, and the identification of the RAID controller
as the essential part of a disk subsystem, a strong demand for suitable RAID controllers has
emerged during the past few years.
Since 1990, ICP vortex has been intensively engaged in the research and development of
RAID products for the highest performance and security requirements. Due to our products’
outstanding performance, our expertise and continuity in development, ICP Controllers are
accepted and known as top leading-edge products all over the world. ICP Controller prod-
ucts within the GDT RD Series offer customers a wide variety of RAID controllers, suitable
for the most different platforms and applications. All ICP Controllers of the GDT RD Series
are pure-bred hardware solutions. All functionality required for the sometimes very complex
tasks is hardware-implemented on the controller. Thus, RAID is fully independent of the
computer system (the host) and the operating system.
Thanks to the wide operating system support and easy-to-use installation and maintenance
utilities, setting up and using high performance and fault-tolerant mass-storage subsys-
tems for almost every purpose is child’s play.
We would like to thank you for purchasing an ICP Controller of the GDT RD Series.

In order to meet the various customer and system requirements, ICP vortex offers 6 differ-
ent Wide/Ultra2 SCSI Disk Array Controllers for PC-based PCI computer systems. The main
differences between the two controllers lie in the number of Wide/Ultra2 SCSI Channels.
