Guide

Introduction

Software clustering technology enables you to make several servers to workas a unit. Various cluster configurations can be implemented. One of the mostfrequently used configurations is the failover cluster. This configurationassumes that if one of the cluster nodes fails, the reserved node automaticallybrings online, serving the applications. With that the workflow remainsuninterrupted and secured.

Failover cluster configuration includes two (or more) server nodes that sharean external storage. Based on the iSCSI technology, StarWind Softwafe Inc.StarWind enables to create an external storage in Windows environmentwithout implementation of expensive FC or external SCSI solutions. WithStarWind you can create a shared disk array on a host running MicrosoftWindows.

This document gives you detailed step-by-step instructions on StarWindconfiguring for failover clusters.
