1. Introduction

1.1. Overview

In this document, I am sharing all the steps I used to create a Windows Server 2012 File Server demo or test environment, so you can experiment with some of the new technologies yourself. You only need a single computer (the specs are provided below) and the ISO file with the Windows Server 2012 evaluation version available as a free download. For the SQL part, you will need the SQL Server 2012 evaluation version, which is also available as a free download.

The demo setup includes 4 virtual machines: one domain controller and iSCSI target, two file servers and a SQL server. You need the iSCSI target and two file servers because we’re using Failover Clustering to showcase SMB Transparent Failover and SMB Scale-Out. We’ll also use multiple Hyper-V virtual networks, so we can showcase SMB Multichannel.

This will probably require a few hours of work end-to-end, but it is a great way to experiment with a large set of Microsoft technologies in Windows Server 2012, including:

Hyper-V
Networking
Domain Name Services (DNS)
Active Directory Domain Services (AD-DS)
iSCSI Target
iSCSI Initiator
Failover Clustering
File Servers
PowerShell

Follow the steps and let me know how it goes in the comment section. If you run into any issues or found anything particularly interesting, don’t forget to mention the number of the step.

1.2. Hardware

You will need the following hardware to perform the steps described here:

Computer capable of running Windows Server 2012 and Hyper-V (64-bit, virtualization technology) with at least 8GB of RAM
An 8GB USB stick, if you’re installing Windows Server from USB and copying the downloaded software around (you can also burn the software to a DVD)
Internet connection for downloading software and updates (DHCP enabled)

1.3. Software

You will need the following software to perform the steps described here:

Windows Server 2012 Evaluation (provided as an ISO file). Download from https://www.microsoft.com/en-us/server-cloud/windows-server/trial.aspx
SQL Server 2012 Evaluation (provided as an ISO file). Download from https://www.microsoft.com/sqlserver/en/us/get-sql-server/try-it.aspx

1.4. Notes and disclaimers

The text for each step also focuses on the specific actions that deviate from the default or where a clear default is not provided. If you are asked a question or required to perform an action that you do not see described in these steps, go with the default option.
Obviously, a single-computer solution can never be tolerant to the failure of that computer. So, the configuration described here is not really continuously available. It’s just a simulation.
The configuration described here is for demo, testing or learning. You would definitely need a different configuration for a production deployment.
A certain familiarity with Windows administration and configuration is assumed. If you're new to Windows, this document is not for you. Sorry...
There are usually several ways to perform a specific configuration or administration task. What I describe here is one of those many ways. It's not necessarily the best way, just the one I personally like best at the moment.
In theory, you could run this demo on a host computer with only 4GB of RAM, but you would need to configure each VM to run with only 512MB of RAM, which is the bare minimum required. It works, but it will run slower.
This blog post is an update on a previous blog post that provided similar steps for Windows Server 2012 Beta. This post supersedes the old one.

2. Install Windows Server 2012

2.1. Preparations

Format a USB disk using Windows 8 or Windows Server 2012.
Copy the contents of the Windows Server 2012 ISO file to the USB disk.
To read the files from within the ISO file using Windows 8 or Windows Server 2012, just double click the ISO file to mount it.
Make sure the computer BIOS is configured for Virtualization. Each computer BIOS is different, so you need to find the right settings.

2.2. Install the OS

Use your computer’s BIOS option to boot from the USB disk.
After “Windows Setup” starts from the USB disk, enter the required information to install the OS:
Select language, time and currency format and keyboard. Then click “Next”.
Click “Install Now”.
Select the “Windows Server Datacenter - Server with a GUI” option and click “Next”.
Accept the license agreement and click “Next”.
Select the “Custom: Install Windows only” option.
Select the install location for Windows Server and click “Next”.
Wait for the installation to complete. This will take a few minutes.
After the installation is completed, the OS will boot.
Type the administrator password twice, then click on “Finish”.

2.3. Rename the computer

2.3.PS. Using PowerShell

Rename-Computer DEMO-HV0 -Restart

2.3.GUI. Using Server Manager

In Server Manager, click on “Local Server” on the list on left.
Click on the default name next to “Computer Name”.
Click on “Change”.
Enter “DEMO-HV0” as the new Computer Name and click “OK”.
Accept the option to restart the computer.

2.4. Enable Remote Desktop

Log in using the Administrator account and enable Remote Desktop.
After completing this step, you will be able work from a Remote Desktop connection.

2.4.PS. Using SCONFIG.EXE

Use a command prompt to start SCONFIG.EXE
Use option 7 in SCONFIG to enable remote desktop

2.4.GUI. Using Server Manager

In Server Manager, click on “Local Server” on the list on left.
Click on the “Disabled” item next to “Remote Desktop”.
Select the option to “Allow connections from computers running any version…”
Click “OK” multiple times until you’re back to the “Local Server” screen.

3. Configure the Hyper-V Host

3.1. Install the Hyper-V role to the server

Install the Hyper-V role and the required management tools. The computer will restart.

3.1.PS. Using PowerShell

Install-WindowsFeature Hyper-V, Hyper-V-PowerShell, Hyper-V-Tools -Restart

3.2.OUT. Sample output

PS C:\> Get-WindowsFeature *Hyper*

Display Name Name Install State
------------ ---- -------------
[X] Hyper-V Hyper-V Installed
[X] Hyper-V Management Tools RSAT-Hyper-V-Tools Installed
[X] Hyper-V GUI Management Tools Hyper-V-Tools Installed
[X] Hyper-V Module for Windows PowerShell Hyper-V-PowerShell Installed

3.1.GUI. Using Server Manager

In Server Manager, click on “Dashboard” on the list on left.
Click on the “Add Roles and Features”, which is option 2 under “Configure this local server”.
On the “Before You Begin” page, just click “Next”.
On the “Installation Type” page, click “Role-base or feature-based installation” and click “Next”.
On the “Server Selection” page, select your server and click “Next”.
On the “Server Role” page, select “Hyper-V”.
On the “Add features that are required for Hyper-V” dialog, click “Add features”, then click “Next”.
On the “Features” page, just click “Next”.
On the “Hyper-V” page, just click “Next”.
On the “Create Virtual Switches” page, just click “Next”.
On the “Virtual Machine Migration” page, just click “Next”.
On the “Default Stores” page, just click “Next”.
On the “Confirmation” page, click “Restart target machine automatically if needed”, click “Yes” to confirm and then click “Install”.
The role will be installed and the computer will restart in the end.

3.2. Create the VM switches

Create one external virtual network (VM switch that is connected to the external network interface).
Create three internal virtual networks (VM switches used just to communicate between the VMs).

3.2.PS. Using PowerShell

Get-NetAdapter
Rename-NetAdapter –InterfaceDescription *Gigabit* -NewName External
New-VMSwitch –Name External -NetAdapterName External
1..3 | % { New-VMSwitch -Name Internal$_ -SwitchType Internal }
Get-VMSwitch
Get-NetAdapter

Note: If you’re connected via “Remote Desktop” to the server, you might temporarily lose the connection when you create the External VMSwitch.
If using DHCP on that interface, you will be able to reconnect. If you’re using static IP addresses, you should run this step locally, not via “Remote Desktop”.

3.2.GUI. Using Hyper-V Manager

In Server Manager, click on “Tools” in the upper left and select “Hyper-V Manager”
In Hyper-V Manager, click on the server name (DEMO-HV0) on the pane on the left
On the task pane on the right, click on the “Virtual Switch Manager”
Use the “New virtual switch” option to add 1 network named “External”, select “External” for type and select your physical NIC. Click “Apply” to confirm.
Use the “New virtual switch” option to add 3 networks named “Internal1”, “Internal2” and “Internal3”, each of type “Internal”.
After creating the four new NICs, you should see the four new NICs in Server Manager, under Local Server

3.3. Rename the network adapters

You should now configure the 4 virtual network interfaces on the parent.
This includes renaming them to the names of the switches and configuring static IP addresses for the 3 internal NICs (the external NIC should be DHCP enabled, so it does not need IP address configuration).

3.3.PS. Using PowerShell

1..3 | % {Rename-NetAdapter *Internal$_* -NewName ParentInternal$_}
Rename-NetAdapter "vEthernet (External)" -NewName ParentExternal
Get-NetAdapter

3.3.OUT. Sample Output

PS C:\> Get-NetAdapter

Name InterfaceDescription ifIndex Status MacAddress LinkSpeed
---- -------------------- ------- ------ ---------- ---------
ParentInternal3 Hyper-V Virtual Ethernet Adapter #5 45 Up 00-15-5D-B5-AE-07 10 Gbps
ParentInternal2 Hyper-V Virtual Ethernet Adapter #4 36 Up 00-15-5D-B5-AE-06 10 Gbps
ParentInternal1 Hyper-V Virtual Ethernet Adapter #3 20 Up 00-15-5D-B5-AE-05 10 Gbps
ParentExternal Hyper-V Virtual Ethernet Adapter #2 16 Up 00-21-9B-31-BA-15 10 Gbps
External Intel(R) 82566DM-2 Gigabit Network C... 12 Up 00-21-9B-31-BA-15 1 Gbps

3.3.GUI. Using Server Manager

In Server Manager, click on “Local Server” on the list on left.
In the properties pane on the right, scroll to see the list of “Wired Internet Connections” (there will be 4 of them, as we showed in the previous Server Manager screenshot).
Click on the “Ipv4 address…” link next to one of the interfaces, the “Network Connections” window will show.
Select the interface that shows as “Enabled” and click on “Rename this connection” to rename it to “External”.
Rename the 3 interfaces on an “Unidentified network” to “Internal1”, “Internal2” and “Internal3”
Close the “Network Connections” and refresh the “Local Server” view.

3.4. Assign static IP addresses for the Hyper-V host

In this step, you will assign a static IP address to the 3 internal virtual NICs on the parent partition.
These NICs initially use the default setting (DHCP), but there is no DHCP server for the internal network.
The table below shows the desired configuration for each interface.

Machine

Parent External

Parent Internal1

Parent Internal2

Parent Internal3

Parent

DHCP

192.168.101.100

192.168.102.100

192.168.103.100

Note 1: The ParentExternal network does not need any further configuration, since the default is already to use DHCP.
Note 2: The preferred DNS IP address for all 3 internal interfaces should be set to 192.168.101.1 (that will be the IP address of the DNS server we will configure later).

3.4.PS. Using PowerShell

1..3 | % {
Set-NetIPInterface –InterfaceAlias ParentInternal$_ -DHCP Disabled
Remove-NetIPAddress –InterfaceAlias ParentInternal$_ -AddressFamily IPv4 -Confirm:$false
New-NetIPAddress –InterfaceAlias ParentInternal$_ -IPAddress "192.168.10$_.100" -PrefixLength 24 -Type Unicast
Set-DnsClientServerAddress –InterfaceAlias ParentInternal$_ -ServerAddresses 192.168.101.1
}

Get-NetIPAddress –AddressFamily Ipv4 | FT

3.4.OUT. Sample Output

PS C:\> Get-NetIPAddress –AddressFamily Ipv4 | Format-Table

ifIndex IPAddress PrefixLength PrefixOrigin SuffixOrigin AddressState PolicyStore
------- --------- ------------ ------------ ------------ ------------ -----------
45 192.168.103.100 24 Manual Manual Preferred ActiveStore

16 10.123.181.174 23 Dhcp Dhcp Preferred ActiveStore
1 127.0.0.1 8 WellKnown WellKnown Preferred ActiveStore

3.4.GUI. Using Server Manager

In Server Manager, click on “Local Server” on the list on left.
In the properties pane on the right, scroll to see the list of Ethernet interfaces (there will be 4 of them)
Click on the “Ipv4 address…” link next to one of the interfaces, the “Network Connections” window will show
On the list of network connections, right click the Internal1 interface and click “Properties”
On the “ParentInternal1 Properties” window, select “Internet Protocol Version 4 (TCP/IPv4)” and click “Properties”.
On TCP/IPv4 Properties window, select the option to “Use the following IP address”.
Enter the IP address 192.168.101.100 and the subnet mask 255.255.255.0 (as shown below).
Select the option “Use the following DNS server address”, enter 192.168.101.1 and click “OK”
Repeat this for the Internal2 and Internal3 networks, making sure to use the correct IP address (see table shown in item 3.4) and use the same Preferred DNS server IP address.
Close the “Network Connections” and refresh the “Local Server” view.

4. Create the Base VM

4.1. Preparations

Create a folder for your ISO files at C:\ISO and a folder for your VMs at C:\VMS
Copy the Windows Server 2012 ISO file to C:\ISO (I renamed the file to WindowsServer2012.ISO)

4.2. Create a Base VM

Create a new VM that will be used as the base image for our 4 VMs.
Store it in the C:\VMS folder and attach the Windows Server 2012 ISO file to it.

4.2.PS. Using PowerShell

MD C:\VMS
New-VHD -Path C:\VMS\BASE.VHDX -Dynamic -SizeBytes 127GB
New-VM -Name Base -VHDPath C:\VMS\BASE.VHDX -SwitchName External -Memory 1GB
Set-VMDvdDrive –VMName Base -Path C:\ISO\WindowsServer2012.ISO
Start-VM Base

4.2.OUT. Sample Output

PS C:\> Get-VM

Name State CPUUsage(%) MemoryAssigned(M) Uptime Status
---- ----- ----------- ----------------- ------ ------

4.2.GUI. Using Hyper-V Manager

In Windows Explorer, create a new C:\VMS folder.
In Server Manager, click on “Tools” in the upper left and select “Hyper-V Manager”.
In Hyper-V Manager, click on the server name on the pane on the left.
On the task pane on the right, click on “New”, then click on “Virtual Machine…”.
On the “Before you begin” page, just click “Next”.
On the “Specify Name and Location” page, use “Base” for the name, and “C:\VMS” for location. Click “Next”.
On the “Assign Memory” page, use “1024” MB and click “Next”.
On the “Configure Networking” page, use “External”.
On the “Connect Virtual Disk” page, select the option to “Create a virtual hard disk”.
Use “Base.vhdx” for name, “C:\VMS” for location and “127” GB for size. Click “Next”.
On the “Installation Options” page, select the option to install from DVD, select the option to use an ISO file and enter the path to the Windows Server 2012 ISO file on your C:\ISO folder. Click “Finish”.
In Hyper-V Manager, right-click the VM and select “Start”

4.3. Install Windows Server 2012 on the VM

In Server Manager, click on “Tools” in the upper left and select “Hyper-V Manager”.
In Hyper-V Manager, click on the server name on the pane on the left.
On the list of VMs, right-click the VM called “Base” and click on “Connect…”
Follow the instructions on the screen, as you did in item 2.2.
Set a password, but don’t install any roles.
Don’t bother renaming the computer, since we’re sysprep’ing the VM anyway.

4.4. Sysprep the VM

After you have the OS installed on the VM, sign in and run C:\Windows\System32\Sysprep\Sysprep.exe
Select the options to run the OOBE, generalize and shutdown
After Sysprep completes, the VM will be shut down.

4.5. Remove the base VM

Remove the BASE VM, leaving just the BASE.VHDX.
You should have a new base VHD ready to use at C:\VMS\BASE.VHD. Its size should be around 9GB.

4.5.PS. Using PowerShell

Remove-VM Base

4.5.GUI. Using Hyper-V Manager

In Hyper-V Manager, click on the server name on the pane on the left
On the list of VMs, right-click the VM called “Base” and click on “Delete”

5. Configure the 4 VMs

5.1. Create 4 new differencing VHDs using the Base VHD

5.1.PS. Using PowerShell

1..4 | % { New-VHD -ParentPath C:\VMS\BASE.VHDX –Path C:\VMS\VM$_.VHDX }

5.1.OUT. Sample Output

PS C:\> Dir C:\VMS

5.1.GUI. Using Hyper-V Manager

In Hyper-V Manager, click on the server name on the pane on the left.
On the task pane on the right, click on “New”, then click on “Hard disk…”
On the “Before you begin” page, just click “Next”.
On the “Choose disk format” page, select “VHDX” and click “Next”.
On the “Choose disk type” page, select “Differencing”.
On the “Specify Name and Location” page, use “VM1.VHDX” for name and “C:\VMS” for location. Click “Next”.
On the “Configure disk” page, use “C:\VMS\BASE.VHDX” for the location of the parent VHD.
After this, you will have a new differencing VHD at VM1.VHD that’s 4MB in size.
Since we’re creating 4 VMS, copy that file into VM2.VHD, VM3.VHD and VM4.VHD.

5.2. Create 4 similarly configured VMs

You should create five VMs as follows:

5.2.GUI. Using Hyper-V Manager

In Hyper-V Manager, click on the server name on the pane on the left.
On the task pane on the right, click on “New”, then click on “Virtual Machine…”
On the “Before you begin” page, just click “Next”.
On the “Specify Name and Location” page, use “VM1” for the name, and “C:\VMS” for location. Click “Next”.
On the “Assign Memory” page, use “1024” MB and click “Next”.
On the “Configure Networking” page, use “External”.
On the “Connect Virtual Disk” page, select the option to “Use an existing virtual hard disk”.
Use “C:\VMS\VM1.vhdx” for name. Click on “Finish”.
In Hyper-V Manager, click on the server name on the pane on the left.
On the list of VMs, right-click the VM you just created (VM1) and click on “Settings…”
On the “Settings for VM1” window, select “Add Hardware”, then “Network Adapter”.
Select the “Internal1” interface and click OK.
Repeat the process for VMs 2 to 4.
For VMs 2 to 4, make sure to add networks Internal2 and Internal3 as well Internal1.

5.3. Start the 4 VMs

5.3.PS. Using PowerShell

Start-VM VM*

5.3.GUI. Using Hyper-V Manager

In Hyper-V Manager, click on the server name on the pane on the left
In Hyper-V Manager, multi-select VMs 1 to 5, right click them and click on “Start”

5.4. Complete the mini-setup for the 4 VMs

Using Hyper-V manager, multi-select VMs 1 to 4, right click them and click on “Connect…”
Let the mini-setup complete, and configure each of the five VMs.
You will be prompted for the usual items, like license agreement, clock/language/region settings and a password.

5.5. Change the computer name for each VM

Change the computer name for each VM, using the names defined in item 5.2
The examples below are for VM1 (the DNS and Domain Controller).
You should repeat this for each of the 4 VMs.
At this point, you can also use this opportunity to enable Remote Desktop for each VM.
This would be done for each VM as you did for the host in item 2.4, if you want to access the VMs remotely.

5.5.PS. Using PowerShell (for VM1, for instance)

Rename-Computer DEMO-DC -Restart

5.5.GUI. Using Server Manager (for VM1, for instance)

In Server Manager, click on “Local Server” on the list on left.
Click on the default name next to “Computer Name”.
Click on “Change”.
Enter the new computer name as “DEMO-DC”.
Click “OK” accept the changes.
Click “OK” to acknowledge that you need to restart to apply changes.
Click “Restart Now”.

5.6. For each VM, configure the networks

In this step you will configure the network for each VM as shown on the table in item 5.2
We first rename the Network Connections in each guest for easy identification.
The External network is identified as being the only one with a DHCP address.
The remaining networks are renamed to Internal1, Internal2 and Internal3.
For internal networks static IPs are configured, with mask 255.255.255.0 and DNS set to 192.168.101.1.
The Internal 1 network will be used for DNS, Active Directory and the iSCSI Target.
The External network is useful for downloading from the Internet and remotely connecting to the 4 VMs.
You could configure a DHCP server for the internal interfaces.
However, due to the risk of accidentally creating a rogue DHCP server in your network, fixed IPs are used.

5.6.PS. Using PowerShell (for VM1, for instance)

## External NIC is the only one with a DHCP server

Get-NetIPAddress -PrefixOrigin DHCP | % {
     Rename-NetAdapter -InterfaceAlias $_.InterfaceAlias –NewName External
}

## $IC – Internal Count – Number of Internal networks

$IC=0
Get-NetAdapter Ethernet* | Sort MacAddress | % {
   $IC++
   Rename-NetAdapter -InterfaceAlias $_.InterfaceAlias –NewName Internal$IC
}

## $VM is the VM Number, between 1 and 4. Used as the last portion of the IP address.

$VM=1
1..$IC | % {

5.6.GUI. Using Server Manager (For VM1, for instance)

This step is similar to step 3.4, but this time performed on the 4 VM.
Inside the VM, in Server Manager, click on “Local Server” on the list on left.
In the properties pane on the right, Click on the “Ipv4 address…” link next to one of the interfaces.
The “Network Connections” window will show.
As you did with the Hyper-V host, rename the NIC with the DHCP connection to “External”.
This NIC needs no further configuration.
Rename the remaining NIC to “Internal1”. (Other VMs will also have Internal2 and Internal3).
For each internal NIC, right click the Internal1 interface and click “Properties”.
On the “Internal1 Properties” window, select “Internet Protocol Version 4 (TCP/IPv4)” and click “Properties”.
On TCP/IPv4 Properties window, select the option to “Use the following IP address”.
Enter the corresponding IP address (see table on item 5.2) and the subnet mask 255.255.255.0.
Select the option “Use the following DNS server address”, enter 192.168.101.1 and click “OK”.
Repeat this for the Internal2 and Internal3 networks using the corresponding IP address and the DNS above.
Close the “Network Connections” and refresh the “Local Server” view.

Note: If you can’t tell which Internal network is which inside the VMs with multiple Internal networks, you can temporarily set one of the adapters to “Not Connected” in the VM Settings and verify which one shows as “Network cable unplugged”.

5.7. Review VM name and network configuration

After renaming the computer, renaming the network and configuring IP addresses, review the configuration on each VM to make sure you did not miss any step. Examples are shown below for VM1 and VM2.

5.7.PS. Using PowerShell

10.3. Planned move of a file server node (with SMB Transparent Failover of SQL Client)

Use SMB Transparent Failover and Witness to move the SMB Client (SQL Server) between the two File Server cluster nodes.
Note: Moves can sometimes take a few seconds to complete, so you might need to repeat the command to see the witness.

10.3.PS. Using PowerShell (from VM2, DEMO-F1 or VM3, DEMO-F2)

Get-SmbWitnessClient | FT ClientName, NetworkName, FileServerNodeName
Move-SmbWitnessClient -ClientName DEMO-DB -DestinationNode DEMO-F1
1..10 | % {Start-Sleep 5; Get-SmbWitnessClient | FT ClientName, NetworkName, FileServerNodeName }

10.3.OUT. Sample output

PS C:\> Get-SmbWitnessClient | FT ClientName, NetworkName, FileServerNodeName

ClientName NetworkName FileServerNodeName
---------- ----------- ------------------
DEMO-DB DEMO-FS DEMO-F1

PS C:\> Move-SmbWitnessClient -ClientName DEMO-DB -DestinationNode DEMO-F2

PS C:\> Get-SmbWitnessClient | FT ClientName, NetworkName, FileServerNodeName

ClientName NetworkName FileServerNodeName
---------- ----------- ------------------
DEMO-DB DEMO-FS DEMO-F1

10.4. Unplanned failure of a file server node (with SMB Transparent Failover of SQL Client)

Restart one of the servers to force an SMB Transparent Failover to move the SMB Client (SQL Server) between the two File Server cluster nodes.
Note: After the failover, the client moves to the surviving nodes transparently (in just a few seconds). However, there will be no witness servers available then. That’s fine, but during that time we’re running with a single surviving file server node, with no witness. After the file server restarts and becomes available again (which could take a minute or so) the client will reconnect to it as a witness and we are back in a two-file-server configuration.

10.4.PS. Using PowerShell (from VM2, DEMO-F1)

Get-SmbWitnessClient | FT ClientName, NetworkName, FileServerNodeName
Restart-Computer –ComputerName DEMO-F2 –Force
1..100 | % { Start-Sleep 5; Get-SmbWitnessClient | FT ClientName, NetworkName, FileServerNodeName }

10.4.OUT. Sample output

PS C:\> Get-SmbWitnessClient | FT ClientName, NetworkName, FileServerNodeName

ClientName NetworkName FileServerNodeName
---------- ----------- ------------------
DEMO-DB DEMO-FS DEMO-F2

PS C:\> Restart-Computer -ComputerName DEMO-F2 -Force

PS C:\> Get-SmbWitnessClient | FT ClientName, NetworkName, FileServerNodeName

PS C:\> Get-SmbWitnessClient | FT ClientName, NetworkName, FileServerNodeName

ClientName NetworkName FileServerNodeName
---------- ----------- ------------------
DEMO-DB DEMO-FS DEMO-F1

10.5. Surviving the loss of a client NIC

Observe that SMB Multichannel will protect the SQL Server from the failure of a NIC.

10.5.PS. Using PowerShell (from VM4, DEMO-DB)

Get-SmbMultichannelConnection
Disable-NetAdapter -InterfaceAlias Internal3 –Confirm:$false ; Start-Sleep 20

Get-SmbMultichannelConnection

Enable-NetAdapter -InterfaceAlias Internal3 ; Start-Sleep 20
Get-SmbMultichannelConnection

DEMO-FS True 192.168.102.4 192.168.102.3 21 16 True False

11. Shut down, startup and install final notes

Keep in mind that there are dependencies between the services running on each VM.
To shut them down, start with VM4 and end with VM1, waiting for each one to go down completely before moving to the next one.
To bring the VMs up, go from VM1 to VM4, waiting for the previous one to be fully up (with low to no CPU usage) before starting the next one.
You might want to also take a snapshot of the VMs after you shut them down, just in case you want to bring them back to the original state after experimenting with them for a while.
If you do, you should always snapshot all of them, again due to dependencies between them. Just right-click the VM and select the “Snapshot” option.
As a last note, the total size of the VHDX files (base plus 4 diffs), after all the steps were performed, was around 19 GB.

12. Conclusion

I hope you enjoyed these step-by-step instructions. I strongly encourage you to try them out and perform the entire installation yourself. It’s a good learning experience.

Note: If you want to print this post, I have attached a printer-friendly PDF version below. Thanks for the suggestion, Keith!
