NetApp PowerShell Toolkit to get storage reports....

I know agood bit about PowerShell but my NetApp knowledge is weak so I apoligize if this is easy.  I have been asked by management to write a script that outputs the following :

These would be broken down by cluster.

Total storage in TB

Storage used in TB and % used

# of vols and LUNs

Then an overall Total TB across all cluster.

Thanks in advance.  Any input is very appreciated.
