Introduction

A Dell™ Failover Cluster combines specific hardware and software

components to provide enhanced availability for applications and services

that are run on the cluster. A Failover Cluster is designed to reduce the

possibility of any single point of failure within the system that can cause the

clustered applications or services to become unavailable. It is recommended

that you use redundant components like server and storage power supplies,

connections between the nodes and the storage array(s), and connections to

client systems or other servers in a multi-tier enterprise application

architecture in your cluster.

This document provides information to configure your Dell|EMC CX3-series

fibre channel storage array with one or more Failover Clusters. It provides

specific configuration tasks that enable you to deploy the shared storage for

your cluster.

For more information on deploying your cluster with Windows Server 2003

operating systems, see the Dell Failover Clusters with Microsoft Windows

Server 2003 Installation and Troubleshooting Guide located on the Dell

Support website at support.dell.com. For more information on deploying

your cluster with Windows Server 2008 operating systems, see the

Dell Failover Clusters with Microsoft Windows Server 2008 Installation and

Troubleshooting Guide located on the Dell Support website at

support.dell.com.

For a list of recommended operating systems, hardware components, and

driver or firmware versions for your Dell Failover Cluster, see the Dell Cluster

Configuration Support Matrix on the Dell High Availability website at

www.dell.com/ha.

8Introduction

Cluster Solution

Your cluster implements a minimum of two node clustering to a maximum of

either eight nodes (for Windows Server 2003) or sixteen nodes

(for Windows Server 2008) clustering and provides the following features:

• 8-Gbps, 4-Gbps, and 2-Gbps Fibre Channel technology

• High availability of resources to network clients

• Redundant paths to the shared storage

• Failure recovery for applications and services

• Flexible maintenance capabilities, allowing you to repair, maintain, or

upgrade a node or storage system without taking the entire cluster offline

Implementing Fibre Channel technology in a cluster provides the following

advantages:

•

Flexibility

— Fibre Channel allows a distance of up to 10 km between

switches without degrading the signal.

•

Availability

— Fibre Channel components use redundant connections

providing multiple data paths and greater availability for clients.

•

Connectivity

— Fibre Channel allows more device connections than

Small Computer System Interface (SCSI). Because Fibre Channel devices

are hot-pluggable, you can add or remove devices from the nodes without

taking the entire cluster offline.

Cluster Hardware Requirements

Your cluster requires the following hardware components:

• Servers (cluster nodes)

• Storage Array and storage management software

Introduction 9

Cluster Nodes

Table 1-1 lists the hardware requirements for the cluster nodes.

NOTE: For more information about supported systems, HBAs and operating system

variants, see the Dell Cluster Configuration Support Matrix on the Dell High

Availability website at www.dell.com/ha.

Table 1-1. Cluster Node Requirements

Component Minimum Requirement

Cluster nodes A minimum of two identical PowerEdge servers are required.

The maximum number of nodes that is supported depends

on the variant of the Windows Server operating system used

in your cluster, and on the physical topology in which the

storage system and nodes are interconnected.

RAM The variant of the Windows Server operating system that is

installed on your cluster nodes determines the minimum

required amount of system RAM.

HBA ports Two Fibre Channel HBAs per node, unless the server employs

an integrated or supported dual-port Fibre Channel HBA.

Where possible, place the HBAs on separate PCI buses to

improve availability and performance.

NICs At least two NICs: one NIC for the public network and

another NIC for the private network.

NOTE: It is recommended that the NICs on each public network

are identical, and that the NICs on each private network are

identical.

Internal disk

controller

One controller connected to at least two internal hard drives

for each node. Use any supported RAID controller or disk

controller.

Two hard drives are required for mirroring (RAID 1) and at

least three are required for disk striping with parity (RAID 5).

NOTE: It is strongly recommended that you use

hardware-based RAID or software-based disk-fault tolerance

for the internal drives.

10 Introduction

Cluster Storage

Table 1-2 lists supported storage systems and the configuration requirements

for the cluster nodes and stand-alone systems connected to the storage

systems.

Table 1-3 lists hardware requirements for the storage processor enclosures (SPE),

disk array enclosures (DAE), and standby power supplies (SPS).

Table 1-2. Cluster Storage Requirements

Hardware Components Requirement

Supported storage

systems

One to four supported Dell|EMC storage systems. See

Table 1-3 for specific storage system requirements.

Cluster nodes All nodes must be directly attached to a single storage

system or attached to one or more storage systems

through a SAN.

Multiple clusters and

stand-alone systems

Can share one or more supported storage systems using

optional software that is available for your storage system.

See "Installing and Configuring the Shared Storage

System" on page 45.
