I think that you waste your money. If possible give it back and when lucky receive a refund. I never setup a Compellent with only one Controller. The installation step with joining both Controllers might be challenging with only one module.  Dell will never send you the license even if a valid one exist because youre not the legal owner from dell perspective. It might also possible that the license already was transferred to another system during an platform upgrade like a DIP or so. Regards,Joerg
Hi, i have some questions for the SC4020. I bought a SC4020 without the controllers. - does the SC4020 works also with one Controller or do i need two to get started ?  - from where do i get a license when i buy a used Controller ? and is it expensive ? this is for private use and for test purpose. Thanks  Koltilabs
