Is it possible to install startwind VSAN without HA?

I know this sounds like a very strange request but can you create a non HA vsan? I.e. on server with local storage, create a starwind iscsi presented volume (that will only be used on that server)? No heartbeat, lose the server or storage and lose the starwind volume etc. I have looked through the powershell scripts but couldnt see a way of creating a 1 node no HA. I can see the "Add-HADevice" command but obviously this needs details of a second node. Would this be what the "createimagefile.ps1" is for? i.e. would this create a single node non HA iscsi target
I have seen that there is a starwind vsan and nas but I was under the impression that this was a VM rather than a more lightweight application that can run on an existing server.
Code: Select all

$fileName="VD01",
$filePath="My Computer\f\Starwind_VD01",
$size=5000000,
$targetAlias="VD015T",
$sectorSize=4096,
$numaNode=0,
$cacheMode="wb",
$cacheSize=128)
Import-Module StarWindX
try
{
Enable-SWXLog
if($sectorSize -eq 4096 -and $size -lt 2)
{
throw "Minimal device size 2MB"
}
$server = New-SWServer -host $addr -port $port -user $user -password $password
$server.Connect()
#create image file
New-ImageFile -server $server -path $filePath -fileName $fileName -size $size
#create device
$device = Add-ImageDevice -server $server -path $filePath -fileName $fileName -sectorSize $sectorSize -NumaNode $numaNode -CacheMode $cacheMode -CacheSize $cacheSize
$device
#create target
$target = New-Target -server $server -alias $targetAlias -devices $device.Name
$target
}
catch
{

finally
{
$server.Disconnect()
