EMC Infrastructure for Virtual Desktops

I'm looking for an updated document to the one provided (see below) by Virtual Geek (chad Sakac) from Friday's e-mail. I have reviewed the document he provided and have the configuration discussed (vSphere 4.0, XenDesktop and NS120). But I'm looking for a recommended configuration that involves EFD disk in place o fthe 450GB FC disks.

Can anyone point me in the rigth direction?

Here is the link to the document I referenced above
