+
+    .SYNOPSIS
+	Report VM Disk IOPS of VMs
+
+    .DESCRIPTION
+    This Function will Create a VM Disk IOPS Report
+
+    .Example
+    Get-VM TST* | Get-VMmaxIOPS -Minutes 60 | FT -Autosize
+
+    .Example
+    $SampleVMs = Get-VM "TST*"
+    Get-VMmaxIOPS -VMs $SampleVMs -Minutes 60
+
+    .PARAMETER VMs
+    Specify the VMs 
+
+	.PARAMETER Minutes
+    Specify the Minutes to report (10080 is one Week)
