You may want to consult the EqualLogic Configuratin Guide: en.community.dell.com/.../2639.equallogic-configuration-guide.aspx, look at the section "4.7 Blade Server Chassis Integration". This should give you a really good idea what you need to do.
Also this link has a lot of useful information as well: en.community.dell.com/.../2632.storage-infrastructure-and-solutions-team-publications.aspx
You also might want to check your support contract, you may have the option to have a Dell Service Tech come out and help you get everything setup properly. Contact your sales team for info.
