(edited 24/5/2011 --> removed old Visio Stencils link).
VisioCafe has been updated with IBM's latest official stencils for use with Microsoft Visio. These include all models of the Storwize V7000, including the newest models: The 2076-312 and 2076-324 (which have the dual port 10 Gbps iSCSI card).
Here is the link to VisioCafe. The Storwize V7000 stencils are in both the IBM-Disk as well as the IBM-Full packages.
Remember you can also find my XIV stencils here:
