Last week I was stumbling through a site provisioning script, when I realized I was missing something that I needed – the ability to create a custom quota template and then apply it to a site collection. After doing some quick Get-Command work to try and find the out-of-the-box PowerShell Cmdlets, I quickly realized there are no OOTB Cmdlets to do this.

I was a little frustrated that this didn’t’ exist, but of course when I come across gaps in the OOTB PowerShell support for Microsoft SharePoint 2010 – I immediately look at that as an opportunity to not only figure out the problem, but to share the solution. Luckily for me, as I’ve done a few times now – I came across the solution in Gary Lapointe and Shannon Bray’s book. While they didn’t have a function, they did detail the essentials on how to create the objects necessary to provision quota templates.

After spending a little time this weekend putting it all together, I’m left with a pretty decent function that allows you to create site quota templates easily using PowerShell!

I have added comment-based help to this function, as my intention was to make it as reusable and thorough as possible. The code is pretty simple, and if you want a detailed walk through – I strongly encourage you to check out Gary and Shannon’s book!

Without further ado, here is the function which I have called New-SPQuotaTemplate. I’m also finishing up two other functions, Get-SPQuotaTemplate and Remove-SPQuotaTemplate – look for those soon!

Simply dot-source the function and then run it like a standard Windows PowerShell Cmdlet.

function New-SPQuotaTemplate {
<#
.Synopsis
	This advanced function creates a new Site Quota Template.
.Description
	This function uses .NET code to instantiate an instance of an 
	SPQuotaTemplate class. Once the object is created, an instance of the 
	SPWebService class is instantiated and the Quota Template is added to the 
	Quota Templates Collection.
.Example
	C:\PS>New-SPQuotaTemplate -Name "Custom" -StorageMaximumLevel 2GB -StorageWarningLevel 1GB -UserCodeMaximiumLevel 100 -UserCodeWarningLevel 75
	
	This example creates an SP Quota Template called Custom with a maximum size
	of 2GB and a warning size of 1GB. Sandboxed solutions are 
	limited to 100, with a warning level of 75.
.Example
	C:\PS>New-SPQuotaTemplate -Name "Custom" -StorageMaximumLevel 4GB -StorageWarningLevel 3GB
	
	This example creates an SP Quota Template called Custom with a maximum size
	of 4GB and a warning size of 3GB
