You should check out these fix tips when you get the step-by-step Windows 2008 r2 cluster configuration on your computer.
- To set up group failover, certain conditions must be met:
“Each node in the cluster must have at least two network adapters. One to improve the environmentThe environment, and the other for the heart rate signal between nodes in the cluster.
“Nodes in a cluster must have access to complex storage, be it SAN, iSCSI, NAS, etc.
“An AD domain in which hosts can belong to the same domain.
“There are other requirements for AD as well. Fortunately, you only need the history of a user with administrative privileges on the node, and therefore privileges to create computer objects and read all properties in the container / OU selected for computers in the accounts domain. - Software owners should complete this exercise
VirtualBox (or another virtualization product of your choice)
“Windows Server StarWind 2008r2
“Free iSCSI SAN Edition
1. Installing VirtualBox and Virtual Machines
1.1 Also download VirtualBox. The installation process is pretty straightforward, I won’t go into details. Now create three machines on the network, each with 1 GB of RAM and 20 GB of file.
Server01: Domain Controller, 2 NICs required
Server02: cluster becomes a node, requires 3 NICs
Server03: Cluster must be bindable, 3 Nets requiredmaps
Give Server02 and Server03 three network adapters each, while Server01 only produces two. 
Purpose of network cards:
Production – Clients activate the cluster through this NIC
iSCSI – Cluster nodes submit URL to shared storage on Server01 on this NIC
Heartbeat – the heartbeat signal between two nodes is transmitted through this network card
1.2 Mount ISO Server 2008R2 on three virtual machines and customize Server 2008R2 Enterprise Edition (full installation). Failover clustering functionality is included only in the 2008R2 Enterprise and Data Center types. You can add Standard Edition Server01 if you like, it doesn’t matter.
Usually messy with hardware and software components. Examples of components are cluster group, cluster server, cluster resource group, and virtual node. Clustered server. A virtual server that is used as a single logical device in the system.
1.3 Rename the three computers Server01, Server02, and Windows server03. Then give them the following IPs
Server01: Nic1, ip = 192.168.0.10, subnet mask = 255.255.255.0, preferred DNS = 192.168.0.10 Ip = 192 nic2, .168.1.10, subnet mask = 255.255.255.0
Server02: Nic1, ip = 192.168.0.20, subnet mask = 255.255.255.0, preferredstrong DNS = 192.168.0.10 Ip = 192 nic2, .168.1.20, subnet mask = 255.255.255.0 Nic3, ip = 192.168.2.20, subnet mask = 255.255.255.0
Server03: Nic1, ip = 192.168.0.30, subnet mask = 255.255.255.0, preferred DNS = 192.168.0.10 Ip = 192 nic2, .168.1.30, subnet mask = 255.255.255.0 Nic3, ip = 192.168.2.30, subnet mask = 255.255.255.0
1.4 Install Virtualbox Guest Additions and restart servers.
2. Installing Active Directory
Click Start> Windows Administrative Methods> Failover Cluster Manager to start the Master Failover Cluster Manager.Click Create Cluster.Click Next.Enter the names of the servers you want to add to the cluster.Click the Add button.Click Next.Select Yes to enable Cluster Services scanning.
2.1 Install Active in the Server01 directory.
Step-by-step instructions for creating a domain controller type in a new Windows Server 2008R2 forest.
2.2 On Server01, open the properties related to NIC2 (for iSCSI). Then go to IPv4 properties, click Advanced and make these changes 
2.3 On server 01, click Start → Administrative Tools → DNS Tools → right click Server01 → Properties and make these changes. 
3. Installing StarWind from iSCSI SAN Free Edition
3.1 Install StarWind SAN iSCSI Free Edition on Server01. You use it for iSCSI and shared storage purposes respectively. Each service / application in the cluster requires its own shared storage.
3.2 After creating the actual target and the Server01 store, connect Server02 and Server03 to the target and evaluate the store. Remember to use the 192.168.1.Ip-Ten address of Server01 to connect to the iSCSI target.
3.3 Initialize the drive that brings it online and create a single volume configured with NTFS only on Server02.
Step-by-step instructions for installing StarWind iSCSI SAN Free Edition, creating targets and storage, and connecting to those targets and storage.
Here I created a branded storage shared volume and assigned the E: drive website to it on Server02. 
4. Set the emergency switch functionerased
Install a failover cluster container on Server02 and Server03. You can create a new domain account (remember to have the required permissions), use any domain-built administrator account to check servers.

If all goes to plan, you should see the following screen. Click OK to continue.
5. Confirm and create a cluster, I would say
Is there a multi site cluster in Windows Server 2008?
With the advent of Windows Server 2008 Failover Clustering, multi-site clustering has become much more feasible, including the introduction of cross-subnet failover, and support for high-latency network communications. I mentioned “Subnet Failover” as a great new feature in Windows Server 2008 Failover Clustering, and it’s a great new feature.
5.1 Click Start – Administrative Tools – Failover Cluster Manager.
5.2 Failover Cluster Manager Right Click – Check Configuration 
5.3. The Validate Configuration Wizard starts. Click “Next”
Start Server Manager.From the Tools menu, select DispFailover Cluster Tcher “.On the Failover Cluster Manager pane, under Administration, select Create Cluster.On the Before You Begin page, click Next.
