But you can create a cluster as a Single Node Cluster which you can't switch applications and services to other nodes. But there is a virtual SAN at vmware. see <a href="http://www.vmware.com/appliances/directory/364" target="_blank" rel="nofollow">iSCSI Virtual SAN</a>.

Could you help me use another way if i don`t have SAN to train ? could i use the sharing folder from the DC ? i tried do that but it was fail. Could you help me ? Thank you in advance , your website very helpful for all tech guys in the world , thanks again . Hi Linglom

Hi, Prashant Thakwani
This step seems to be new in Windows Server 2008 that it’ll validate configuration on your environment before create clustering.
“Validate” in Windows Server 2008 Failover Clustering is your friend

Since I’ve not tried on 2008 yet, I’m not sure about these messages.

The “192.168.1.9″ is the quorum disk. It’s a iSCSI SAN storage. I have mentioned about quorum disk in the part 1. If you already have SAN storage configured on the servers, you can skip to the next part.

To Michael A Cooper,
You’re welcome.

Your article is awesome it really is the thing I didn't understand was that there was suppose to be a NAS/SAN already in place. My bad please don't change anything on my account like I said I am still very new to this so I will get up to speed very soon. Thank you for your contribution it's an awesome start for those who are in the lack of knowledge state for this technology. Michael Hey Liglom,

What does this IP mean? In the first part it was mentioned that there are only three servers needed. Doesnt that mean that five IPs for all three servers, that includes the heartbeat ips on the cluster nodes. I am totally new to iscsi initiator stuff. Sorry, if i am asking something wierd. Regards Prashant Thakwani Linglom,
