I did some polishing of your script and came to this:

Connect-VIServer -Server $server
$dsnum = 2
Get-Cluster "cluster1" | Get-VM | ForEach-Object {
	$vm = $_
	$Datastores = $vm | Get-Datastore
	$Count = ($Datastores | Measure-Object).Count
	if ($Count -ge $dsnum )
	{
		Write-host "Listed DataStores $Datastores" -BackgroundColor DarkMagenta -ForegroundColor White
		Write-Host "Match $($vm.Name)" -fore Blue 
		$vm | New-Snapshot -Name "Snap01" 
		$vm | Get-Snapshot | Remove-Snapshot -confirm:$false
		$NewDatastores = $vm | Get-Datastore 
		write-host "Updated $($vm.Name) Listed DataStores $NewDatastores" -ForegroundColor Cyan
	}
	else {
		write-host "Server Not Matched $($vm.Name)" -BackgroundColor Black -ForegroundColor White
	}
}
Disconnect-VIServer -confirm:$false

I didn't test the script. But I would like to hear from you if it works oke.
