Andrew Kutz, a fellow member of the Austin community, has recently released a new VI 2.5 client plug-in to help invoke the new VMware Storage VMotion technology.  The plug-in is free to use, so I invite you to check it out.

Description: 

SVMotion is a VI 2.5 client plugin (the FIRST released, third-party plugin in fact) that extends the client's functionality by providing an integrated, graphical tool that can be used to invoke storage VMotion (SVMotion) operations. This plugin is not supported by VMware. In fact, the plugin is not anywhere close to supported by VMware because it is the result of a two-week dive into the inner-workings of the VI client libraries with popular reflection tools (reverse-engineering). l o s t c r e a t i o n s is working on a white paper that describes how to build VI plugins.

The tool is already becoming popular with VMware VMTN forum community members.  You can talk about it with them, here.
