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 noth­ing 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 "Clus­ter" 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 be­cause of our products’ outstanding performance, our expertise and continuity in develop­ment, 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 hard­ware-implemented on the controller. Thus, RAID is fully independent of the computer sys­tem (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 installa­tion 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 de­tails 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 suf­ficient distances between the two servers and the RAID enclosure.

All ICP Controllers with Clustering functionality have a 6 after the first number of the prod­uct 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, Ul­tra 160 SCSI or Fibre Channel Controller can be upgraded to an ICP Controller with Clus­tering functionality.

WU2 = Wide/Ultra2 SCSI / U160 = Ultra160 SCSI / FC = Fibre Channel Arbitrated Loop / WU = Wide/Ultra / NU = Narrow/Ultra

For the successful installation and setup of Clustering Systems not only the computer sys­tems, the RAID Controllers and mass storage enclosures are important, but also the acces­sories, 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 en­closures 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 Con­trollers, 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 devel­oped 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 be­tween two SCSI bus segments. Both segments can be based on different transfer technolo­gies (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 Con­troller) 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 termi­nation 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.

A.5 ICP vortex Accessories for Fibre Channel Controllers

A.5.1 ICP Fibre Hub 1016

Different to other solutions, the ICP Fibre Hub 1016 is designed not only for typical configu­rations which require a hub, but also for mission critical SAN and Clustering applications.

The 19” enclosure hosts two fully independent Hub Modules and two fully independent power
supplies. Each Hub Module contains two loops with 4 ports per loop. With ICP Fibre Hub
1016 in a Dual Loop setup not only the loops are redundant, but also the hubs and power
supplies.

The ICP Fibre Hub 1016 is able to connect up to 16 FC-AL devices in a physical star,

while keeping the devices in a logical ring configuration.

Connections to the hub use DB-9 connectors. Non-operating devices are automatically by­passed and newly communicating devices are automatically entered onto the loop. Full
Duplex operation per port with 1.0625 Gbit/sec. Repeater function per Port.

The ICP Fibre Hub 1016 can be symmetrically divided into 2, 3 or 4 separate loops with 4 ports
in each loop by using configuration switches.

12 of the 16 ports support the use of external Media Interface Adapters (MIAs)

A.5.2 ICP vortex Fibre Channel Cables and MIAs

MIA adapters transform the electrical signals used by copper cables into optical signals
transmitted by optical fibers. One end of the adapter has an FC DB 9 male connector and
the other end has an SC duplex female connector for the optical fiber.
The adapter uses a laser diode to transform electrical signals into light signals and an opti-

cal sensor to perform the reverse function. 12 of the 16 ports of the ICP Fibre Hub 1016
support MIAs.

B. Installation Notes

B.1 Hardware Installation

Wide/Ultra2 SCSI or Ultra 160 SCSI channels which are used as a shared I/O bus require per
shared channel 2 SCSI Wonders to make sure that the shared channel continues to work
even if a server is switched off, or if the bus is separated from the ICP Controller in one of
the servers.

For the configuration of Cluster Systems with ICP Fibre Channel Controllers, it is recom­mended to use the ICP Fibre Hub 1016, which ensures that the loop is always closed even if
one Controller fails, or if the fibre channel cable is removed. ICP Controllers with two inde­pendent loops allow the set up of a dual loop configuration. In such a configuration, there
is not only redundancy at server level but also at I/O channel level: One loop can fail and
the system continues to run on the other loop. ICP Fibre Hub 1016 was specifically de­signed for such dual loop configurations (it consists of two independent Hub Modules and
two independent power supplies).

B.2 Using Wide/Ultra2 and Ultra 160 SCSI ICP Controllers

Both ICP Controllers for the two nodes should be identical (same model, same firmware
level).

Before connecting both controllers to the shared I/O cable, one of the IOPs (Input/Output
Processor) on one of the controllers must be set to another ID e.g., ID6). This has to be
done for all I/O channels which are used as Clustering channels. The easiest way to change
the IOP IDs is to use ICPCON (ICP RAID Console) loaded with <CTRL>+<G> from the con­troller's ROM.
