Important Note
Using modern RAID Systems significantly increases data security and availability. Under no
circumstances does it relieve you from a careful and daily backup on tape or a similar backup
media. This is the only method to protect your valuable data against total loss (e.g.,
through fire or theft), accidental deletion, or any other destroying impacts.

A. Introduction
In today's information technology world, High Availability Systems are gaining more and
more importance. The demands on these systems are not only the continuous availability
of all important data, i.e., "365 days * 24 hours", but also efficient resource sharing of the
relatively expensive components. The secret behind the popular word "Clustering" is noth-
ing more than the intelligent combination of several computer systems with the purpose to
simultaneously increase the security and computing power of the whole system. This "Clus-
ter" appears to the user just like one single system with extraordinary characteristics. A
special Clustering software executes the controlling and management of the Cluster and its
members.
There are several strategies to design Clustering systems. In a first model, the various
members (also called nodes) could only be connected with each other through the normal
User LAN. In another step, the nodes could additionally share an I/O bus (e.g., SCSI, Fibre
Channel). To avoid "Single Points of Failure" (these are vital components which cause a
general failure if they fail) in such systems, host based RAID controllers are ideally suitable
for cluster systems. The choice of host based RAID controllers for the nodes of a cluster
system implements the appropriate redundancy and security in the mass storage part of
the system right from the beginning. In contrast to this, external RAID controllers carry the
risk of becoming a single point of failure. If they fail the whole cluster system goes down.
Apart from that, these kinds of solutions are normally pretty inhomogeneous: The host
adapters come from vendor A, the external RAID controller from vendor B. Who guarantees
the flawless and interefence-free operation of both components ? Who supports you when
the system causes problems ?
Since 1990 ICP vortex has been intensively engaged in the research and development of
host based RAID products for highest performance and security requirements. Not only be-
cause of our products’outstanding performance, our expertise and continuity in develop-
ment, but also due to our excellent customer support, ICP Controllers are accepted and
known as top leading-edge products all over the world. All ICP Controller products are
pure-bred hardware solutions. All functionality required for the very complex tasks is hard-
ware-implemented on the controller. Thus, RAID is fully independent of the computer sys-
tem (the host) and the operating system. Software RAID solutions are normally not usable
for cluster systems. Thanks to the wide operating system support and easy-to-use installa-
tion and maintenance utilities, setting up and using high performance and fault-tolerant
mass-storage subsystems for almost every purpose is child’s play.
For a successful installation of a Clustering System it is very important that the person who
carries out the installation has detailed knowledge and experience in the areas Microsoft®
Windows NT/2000 Server, Microsoft®Cluster Server, Novell/Orion, Linux/Watchdog and ICP
Disk Array Controllers.
This Addendum contains important information, particular regarding the operation of ICP
RAID Controllers in a Clustering System.
Information on the Operating System, the functioning of the Cluster and other system de-
tails may be found in the corresponding system manuals.
For information on the installation of the ICP Disk Array Controller and the configuration of
Disk Arrays, please refer to the "User's Manual" or "Quick Installation Guide" of your ICP
Controller. These documents may also be found on the ICP System CDROM.
We would like to thank you for purchasing an ICP Controller.

A.1 ICP Controllers in a Cluster Configuration
Due to the required cable lengths (several meters) for the shared I/O channel(s) and the
demands on the transfer performance and quality, only Wide/Ultra2 SCSI, Ultra 160 SCSI or
Fibre Channel controllers are suitable for Clustering. Using such controllers allows for suf-
ficient distances between the two servers and the RAID enclosure.
All ICP Controllers with Clustering functionality have a 6 after the first number of the prod-
uct name. ICP Controllers currently available with Clustering functionality are:
Wide/Ultra2 SCSI, 32-Bit PCI: GDT6618RD, GDT6628RD, GDT6638RD, GDT6658RD
Wide/Ultra2 SCSI, 64-Bit PCI: GDT7618RN, GDT7628RN, GDT7638RN, GDT7658RN
Ultra 160 SCSI, 64-Bit PCI: GDT7623RN, GDT7643RN, GDT7663RN
Fibre Channel, 64-Bit PCI: GDT7619RN, GDT7629RN
By using the Cluster Module (Part No.: 8780), every 65.. and 75.. ICP Wide/Ultra2 SCSI, Ul-
tra 160 SCSI or Fibre Channel Controller can be upgraded to an ICP Controller with Clus-
tering functionality.

For the successful installation and setup of Clustering Systems not only the computer sys-
tems, the RAID Controllers and mass storage enclosures are important, but also the acces-
sories, such as cables, terminators, Fibre Channel Hubs and SCSI Bus Repeaters, Isolators
or Converters. ICP vortex offers a variety of genuine high quality accessories, which are
highly recommended for Clustering Systems.
For external mass storage enclosures we have tested various products. “Fortra”Series en-
closures of the company JMR are pretty often used. A list of vendors can be found in the
appendix of this addendum.

A.4 ICP vortex Accessories for SCSI Controllers
ICP vortex offers various SCSI accessories for the setup and installation of Cluster Systems
based on SCSI technology. These accessories are not only usable for SCSI ICP RAID Con-
trollers, but also for Controllers with SCSI interfaces from other vendors.
A.4.1 SCSI Wonder
SCSI Wonder is a very powerful and universal add-on for SCSI bus systems. It was devel-
oped with a special focus on Cluster Systems with parallel SCSI busses, but may also be
used for totally different tasks (also in combination with SCSI RAID Controllers or SCSI
Host Adapters of other vendors). SCSI Wonder allows a fully transparent connection be-
tween two SCSI bus segments. Both segments can be based on different transfer technolo-
gies (SE or LVD). SCSI Wonder does not require a SCSI ID on the SCSI bus and has no SCSI
bus protocol functions. SCSI Wonder is for both, the initiator (normally the SCSI RAID Con-
troller) and the targets (the hard disks, CDROMs, DLTs, DATs, etc.) „invisible“.
SCSI Wonder can take over the following tasks:
Extension of an existing SCSI bus segment (up to 3 SCSI Wonder
can be used on one SCSI bus):
Connection of two LVD SCSI bus segments (LVD <-> LVD)
Connection of two SE SCSI bus segments (SE <-> SE)
Conversion of a SE SCSI bus segment into an LVD SCSI bus segment
and vice versa (SE <-> LVD; LVD <-> SE)
Installation of T-connections (stubs)

17
Isolation of two SCSI bus segments:
This brings a lot of security for Cluster Systems; SCSI bus segments can be separated or
reconnected without any detrimental effects for the SCSI bus (i.e., the other vital Server
node).
SCSI Wonder as an Isolator fulfills two primary tasks. First, it maintains a proper termi-
nation of the shared SCSI bus, even if one Node is removed. Second, it keeps the SCSI
bus signal quality on all remaining segments on an extremely good and healthy level.
