Visio stencils for DD3300 and newer models

Good morning!

I'm trying to find visio stencils for several Data Domain models (2500, 3300, 6300, and others). Can someone point me to a link where I can download them? If they're listed under another name than DDxxxx, it would be helpful to know that, too. I'd like to have my maps looking crisp, not with a bunch of generic boxes.
