SC100/SC120 Expansion Enclosure Drives

Dell Enterprise hard disk drives (HDDs) and Dell Enterprise solid-state drives (SSDs) are the only drives that

can be installed in

SC100/SC120 expansion enclosures. If a non-Dell Enterprise drive is installed, the

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.
