In 2013, there is no excuse for this. Dell Force10 mandates that I must register to get access to any information about the product.
Getting access to manuals should be freely available. As an independent consultant, I need to perform paper review of your product and this means access to manuals. I don’t have an account and won’t sign up for one for fear of being spammed to death by overzealous Dell marketing
Manuals behind registration walls means that your product don’t get considered. A manual is both a technical resource and marketing collateral for your product and should/must be freely available just like technical specs and product briefs.
Fail, Dell, fail.
