There’s been some information published around External BLOB storage in Technet – you can look at the information here. Also, Kaneboy has uploaded some code to CodePlex that allows the user to merely install and activate the feature. I’m glad someone wrote some code I could use in a demo 🙂
You activate the feature at the farm level and you have to activate it across all WFE’s in order for the operation to be consistent throughout the farm. Thanks for sharing Kaneboy!
