I am interested in your SC942S chassis but it only supports up to 10 drives. Do you have a chassis that supports 15 drives? Or can I make changes in this chassis to support this capability?
You can add an additional mobile rack CSE-M35S in top three 5.25" inch bays which gives you total 15 hard drives. However, please make sure that you use a controller that has at least 3 channels.
