Introduction 5

Introduction

This document provides information for installing and managing your

Cluster solution using Dell PowerVault MD3200i and MD3220i storage

systems. It is intended for experienced IT professionals who need to configure

the cluster solution, and for trained service technicians who perform upgrade

and maintenance procedures. This document also addresses readers who are

new to clustering.

Overview

A Microsoft Windows Server Failover Clustering 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 system and storage

power supplies, connections between the nodes and the storage array(s),

connections to client systems, or other systems in the multi-tier enterprise

application architecture in your cluster.

This guide addresses the configuration of your Dell MD3200i and MD3220i

iSCSI storage arrays for use with one or more Windows Server failover

clusters. It provides information and specific configuration tasks that enable

you to deploy the shared storage for your cluster.

For more information on deploying your cluster, see the Dell Failover Clusters

with Microsoft Windows Server Installation and Troubleshooting Guide at

support.dell.com/manuals.

NOTE: Throughout this document, Windows Server 2008 refers to Windows Server

2008 x64 Enterprise Edition or Windows Server 2008 R2 x64 Enterprise Edition.

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

driver or firmware versions for your Dell Windows Server Failover Cluster, see

the Dell Cluster Configuration Support Matrices at dell.com/ha.

6Introduction

Cluster Solution

Your iSCSI cluster implements a minimum of two-node clustering and a

maximum of sixteen-node clustering and provides the following features:

• Internet Small Computer System Interface (iSCSI) technology

• High availability of system services and 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 cluster node without taking the entire cluster offline

Implementing iSCSI technology in a cluster provides the following

advantages:

•

Flexibility

—as iSCSI is based on TCP/IP, it allows cluster nodes and

storage systems to be located at different sites.

•

Availability

—iSCSI components use redundant connections, providing

multiple data paths and greater availability for clients.

•

Connectivity

—iSCSI allows more device connections than SCSI. Because

iSCSI devices are hot-swappable, you can add or remove devices from the

nodes without bringing down the cluster.

Cluster Requirements

Your cluster requires the following components:

• Servers (cluster nodes)

• Storage and storage management software

Introduction 7

Cluster Nodes

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

Table 1-1. Cluster Node Requirements

Component Minimum Requirement

Processor At least one processor for each cluster node.

Cluster Nodes A minimum of two identical PowerEdge systems.

RAM At least 1 GB RAM on each cluster node.

iSCSI Initiator Complete installation of the iSCSI port driver, Initiator Service,

and Software Initiator on each node.

NOTE: Microsoft Multipath I/O (MPIO) Multipathing Support for

iSCSI is not installed.

Network

Interface Cards

(NICs) for iSCSI

access

Two iSCSI NICs or NIC ports per node. Place the NICs on

separate PCI buses to improve availability and performance.

TCP/IP Offload Engine (TOE) NICs are also supported for iSCSI

traffic. For a list of recommended operating systems, hardware

components, and driver or firmware versions for your Dell

Windows Server Failover Cluster, see the Dell Cluster

Configuration Support Matrices at dell.com/ha.

8Introduction

Cluster Storage

Table 1-2 provides the configuration requirements for the shared storage

system.

NOTE: RAID 0 and independent disks are possible but are not recommended for a

high-availability system because they do not offer data redundancy if a disk

failure occurs.

NICs (public and

private)

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 internal disks for each node. Use any

supported Redundant Array of Independent Disks (RAID)

controller or disk controller.

Two physical disks are required for mirroring (RAID 1) and at least

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

NOTE: It is recommended that you use hardware-based RAID or

software-based disk-fault tolerance for the internal drives.

Table 1-2. Cluster Storage Requirements

Hardware

Components

Minimum Requirement

Supported storage

systems

One Dell PowerVault MD3200i or MD3220i RAID enclosure.

Up to seven Dell PowerVault MD1200 and MD1220 expansion

enclosures with a maximum of 96 disks.

Power and cooling

requirements

Two integrated hot-swappable power supply/cooling fan

modules.

Physical disks At least two physical disks in the PowerVault MD3200i or

MD3220i RAID enclosure.

Multiple clusters and

stand-alone systems

In a switch-attached configuration, clusters and stand-alone

systems can share one or more PowerVault MD3200i or

MD3220i systems.

Introduction 9

Cluster Storage Management Software

Dell PowerVault Modular Disk Storage Manager

The software runs on the management station or any host attached to the

array to centrally manage the PowerVault MD3200i and MD3220i RAID

enclosures. You can use Dell PowerVault Modular Disk Storage Manager

(MDSM) to perform tasks such as creating or managing RAID arrays, binding

virtual disks, and downloading firmware.

MDSM is a graphical user interface (GUI) with wizard-guided tools and a

task-based structure. MDSM is designed to:

• Reduce the complexity of installation, configuration, management, and

performing diagnostic tasks for the storage arrays.

• Contain an event monitoring service that is used to send alerts when a

critical problem with the storage array occurs.

• Provide a command line interface (CLI) to run commands from an

operating system prompt.

Modular Disk Storage Manager Agent

This software resides on each cluster node to collect system-based topology

data that can be managed by the MDSM.

Multipath Software

Multipath I/O software (also referred to as the failover driver) is a software

residing on each cluster node that provides management of the redundant

data path between the system and the RAID enclosure. For the multipath

software to correctly manage a redundant path, the configuration must

provide for redundant NICs and cabling.

The multipath software identifies the existence of multiple paths to a virtual

disk and establishes a preferred path to that disk. If any component in the

preferred path fails, the multipath software automatically re-routes I/O

requests to the alternate path so that the storage array continues to operate

without interruption.

10 Introduction

Advanced Features

Advanced features for the PowerVault MD3200i and MD3220i RAID storage

systems include:

•

Snapshot Virtual Disk

—Captures point-in-time images of a virtual disk

for backup, testing, or data processing without affecting the contents of

the source virtual disk.

•

Virtual Disk Copy

—generates a full copy of data from the source virtual

disk to the target virtual disk in a storage array. You can use Virtual Disk

Copy to back up data, copy data from disk groups that use smaller-capacity

physical disks to disk groups using greater capacity physical disks, or restore

snapshot virtual disk data to the source virtual disk.

NOTE: For instructions on deploying the correct options in the cluster

environment, see "Using Advanced (Premium) PowerVault Modular Disk

Storage Manager Features" on page 61.
