Go to support.emc.com go to Support->Support by Product  Search individually for OneFS, InsightIQ, and the specific node types you own. For each of these click on them and then in the upper right there will be two ways to subscribe:  + Add to My Products and + Add Product Subscription  Click the + sign for both of these for all products.
Currently I don't get e-mail updates on new OneFS software releases.
How do I signup for alerts on new software releases?
