SC100/SC120 Expansion Enclosure Drives

Dell Enterprise hard disk drives (HDDs) and Enterprise Solid-State Drives (eSSDs) are the only drives that
can be installed in SC100/SC120 expansion enclosures. If a non-Dell Enterprise drive is installed, Storage
Center prevents the drive from being managed.
The drives in an SC100 expansion enclosure are installed horizontally. The drives in an SC120 expansion
enclosure are installed vertically. The indicators on the drives provide status and activity information.
