This document provides information for installing and connecting peripheral hardware, storage,
and storage area network (SAN) components for your Dell™ PowerEdge™ Cluster FE400 solution.
The configuration information in this document is specific to the Microsoft
®
Windows®2000
Advanced Server and Windows Server 2003, Enterprise Edition operating systems.
This document covers the following topics:
• Configuration information for installing peripheral hardware components, such as HBAs,
NICs, and PCI adapter cards into Cluster FE400 configurations
• Configuration rules and guidelines for direct-attached or SAN-attached configurations
• Best practices
NOTE: Configurations not listed in this document may not be certified or supported by Dell or Microsoft.
NOTE: In this guide and in other cluster documentation, the Microsoft Cluster Service (for Windows 2000
Advanced Server or Windows Server 2003, Enterprise Edition) is also referred to as MSCS.
Supported Cluster Configurations
This section provides information about supported cluster configurations for your
PowerEdge cluster configuration.
The Cluster FE400 solution supports the following configurations:
®
• Two-node clusters running the Microsoft
system.
• Clusters with up to eight nodes running the Windows Server 2003, Enterprise Edition
operating system.
Table 1-1 provides a list of supported cluster configurations for the Cluster FE400 systems running
Windows 2000 Advanced Server or Windows Server 2003, Enterprise Edition.
Windows® 2000 Advanced Server operating
NOTE: Each cluster node must be of the same system model and have two or more processors.

High-Availability Cluster Configurations
This section provides information about the supported operating systems, HBAs, and HBA drivers
for your cluster configuration.
NOTICE: All cluster nodes in a Cluster FE400 solution must run the same operating system.
Mixing Windows 2000 Advanced Server and Windows Server 2003, Enterprise Edition in the same cluster
is not supported except during a rolling upgrade.
www.dell.com | support.dell.com
NOTICE: HBAs installed in clusters using redundant paths must be identical. Cluster configurations are
tested and certified using identical HBAs installed in all of the cluster nodes. Using dissimilar HBAs in
your cluster nodes is not supported.
Service Pack Support
Windows 2000 Advanced Server
Microsoft Windows 2000 Service Pack 4 or later is required for Cluster FE400 systems that use
Windows 2000 Advanced Server.
You can download the latest service pack from the Microsoft Support website at
support.microsoft.com
for a detailed list of
.
Windows Server 2003, Enterprise Edition
At the time this document was printed, a service pack was not available for Windows Server 2003,
Enterprise Edition. However, hotfix KB818877 and the most recent hotfix for storport.sys
are required.
See Knowledge Base article KB818877 on the Microsoft Support website at
for more information. At the time this document was printed, KB838894 was the most recent
hotfix for storport.sys. You can also go to the Dell Support website at
recent information on this issue.

Fibre Channel Switches
• Dual (redundant) fabric configurations are required.
• A maximum of 16 switches may be used in a SAN.
• A minimum of two and a maximum of eight Inter-Switch Links (ISLs) may exist between any
two directly communicating switches. A single ISL is permitted only when connecting to a
remote switch in an EMC
®
MirrorView™ configuration.
• A maximum of three hops (the number of ISLs each data frame must traverse) may exist
between a host and a storage system.
Rules and Guidelines
When configuring your cluster, all cluster nodes must contain identical versions of the following:
Platform Guide 5
• Operating systems and service packs
• Hardware, drivers, firmware, or BIOS for the NICs, HBAs, and any other peripheral
hardware components
• Systems management software, such as Dell OpenManage™ systems management software
and EMC Navisphere
Maximum Distance Between Cluster Nodes
The maximum cable length allowed from an HBA to a switch, an HBA directly connected to a
storage system, or a switch to a storage system is 300 meters using multimode fiber at 2 Gb/sec.
The total distance between an HBA and a storage system may be increased through the use of
switch ISLs.
www.dell.com | support.dell.com
The maximum cable length for Fast Ethernet and copper Gigabit Ethernet is 100 meters, and for
optical Gigabit Ethernet, it is 550 meters. This distance may be extended using switches and
VLAN technology. The maximum latency for a round-trip network packet between nodes is
500 milliseconds.

Best Practices
This section provides best practices for troubleshooting issues that may occur in your cluster.
•
Incorrect TimeOutValue setting in the Registry.
When you run the Cluster Configuration wizard on a cluster solution running Windows
Server 2003, the wizard modifies the following registry value:
14 Platform Guide
for more information
support.dell.com
.
HKLM\System\CurrentControlSet\Services\Disk\TimeOutValue
The disk
TimeOutValue
setting is the timeout value set by Windows for storage system I/O
operations. The Dell | EMC Fibre Channel storage environment requires 60 seconds for I/O
operations. When you run the Cluster Configuration wizard, the wizard sets the
TimeOutValue
setting to 20 seconds, which may not be sufficient for complex I/O operations.
Consequently, storage system I/O operations may continually time out.
Microsoft has confirmed a problem with the wizard and has implemented hotfix KB818877 to
resolve this issue. See Microsoft Knowledge Base article KB818877 on the Microsoft Support
website at
support.microsoft.com
for more information.
To resolve this issue, read the Knowledge Base article for instructions about how to obtain the
required Quick Fix Executable (QFE) file from Microsoft. Download and apply the QFE as
soon as possible.
If you
have not
configured your cluster, apply the QFE (or Service Pack 1 when available) to all
of the cluster nodes.
If you have configured your cluster, perform one of the following procedures and then reboot
each cluster node, one at a time:
– Manually change the registry
TimeOutValue
setting to 60 on each cluster node.
– Download the Cluster Disk Timeout Fix utility from the Dell Support website at
support.dell.com
When prompted, type the name of your cluster in the

• Using a Tape Backup Library in a SAN
Cluster FE400 solutions-based on Windows 2000 Advanced Server- that are configured with
Emulex HBAs can be connected to one or more tape backup libraries that can be shared with
other clusters and systems in a SAN. To avoid disrupting I/O activities from other network
systems to the tape drive and to ensure cluster failover operations, disable the target reset to
the tape device.
