<h2>Creating the RAM Disk</h2>

<ol>
	<li>Launch Powershell as administrator</li>
	<li>Enter the following commands to create the RAM disk, replacing the IP address with the current server&#39;s IP address
	<div class="codeBlock PS"># allow iSCSI loopback registry setting<br />
	Set-ItemProperty -Path &#39;HKLM:\SOFTWARE\Microsoft\iSCSI Target&#39; -Name AllowLoopBack -Value 1<br />
	# start the iscsi initiator service<br />
	Start-Service -Name MSiSCSI<br />
	# set the iscsi initiator service to start automatically<br />
	Set-Service -Name MSiSCSI -StartupType Automatic<br />
	# create the ram disk, changing size as needed<br />
	New-IscsiVirtualDisk -Path &quot;ramdisk:RAMDisk.vhdx&quot; -Size 256MB<br />
	# initialize iSCSI target<br />
	New-IscsiServerTarget -TargetName RAMDisk -InitiatorIds @(&quot;IPAddress:192.168.0.65&quot;)<br />
	# connect to the ram disk<br />
	Add-IscsiVirtualDiskTargetMapping -TargetName RAMDisk -DevicePath &quot;ramdisk:RAMDisk.vhdx&quot;</div>
	</li>
	<li>Back in Server Manager, select Tools &gt; iSCSI Initiator</li>
	<li>Enter the IP address in the Target field &gt; Click Quick Connect...</li>
	<li>Click Done</li>
	<li>Back in Powershell, run the following command
	<div class="codeBlock PS"># initialize the disk as NTFS<br />
	Get-Disk | Where partitionstyle -eq &#39;raw&#39; | Initialize-Disk -PartitionStyle MBR -PassThru | New-Partition -DriveLetter R -UseMaximumSize | Format-Volume -FileSystem NTFS -NewFileSystemLabel &quot;RAMDisk&quot; -Confirm:$false</div>
	</li>
	<li>Open File Explorer and the new RAM disk should be listed as a usable NTFS drive</li>
</ol>

<h2>Re-creating the RAM Disk on Boot</h2>

<p><em>After the RAM disk has been setup initially, follow the steps below to have it recreated on system boot.</em></p>

<ol>
	<li>Open a text editor</li>
	<li>Paste the following Powershell commands, changing the size as needed
	<p>New-IscsiVirtualDisk -Path &quot;ramdisk:RAMDisk.vhdx&quot; -Size 256MB<br />
	Add-IscsiVirtualDiskTargetMapping -TargetName RAMDisk -DevicePath &quot;ramdisk:RAMDisk.vhdx&quot;<br />
	Get-Disk | Where partitionstyle -eq &#39;raw&#39; | Initialize-Disk -PartitionStyle MBR -PassThru | New-Partition -DriveLetter R -UseMaximumSize | Format-Volume -FileSystem NTFS -NewFileSystemLabel &quot;RAMDisk&quot; -Confirm:$false</p>
	</li>
	<li>Save the file as ramdisk.ps1 to a safe location to run from, c:\scripts for example</li>
	<li>Click on the Start Button &gt; Type task &gt; Launch Task Scheduler</li>
	<li>Right click the Task Scheduler Library folder in the left pane &gt; Create Basic Task...</li>
