So I think this should be a simple enough question but my google-fu is not turning up an answer.
I am wondering what the maximum size a single physical disk can be under the SAS-2 6Gbps spec. I remember from past experience that a SAS-1 controller will see only the first 2 TB of a disk which is larger. I am putting together a backup server which uses SAS-2 controllers and expander backplanes. Given the application, I'm looking for storage density over performance but I don't want to buy drives that are larger than my controllers can address.
