SC200/SC220 Expansion Enclosure Drives

Dell Enterprise Plus hard disk drives (HDDs) and Dell Enterprise Plus solid-state drives (SSDs) are the only
drives that can be installed in SC200/SC220 expansion enclosures. If a non-Dell Enterprise Plus drive is
installed, the Storage Center prevents the drive from being managed.
The drives in an SC200 expansion enclosure are installed horizontally. The drives in an SC220 expansion
enclosure are installed vertically. The indicators on the drives provide status and activity information.

SC200/SC220 Expansion Enclosure Drive Numbering

In an SC200/SC220 expansion enclosure, the drives are numbered from left to right starting from 0.
The Storage Center identifies drives as XX-YY, where XX is the unit ID of the expansion enclosure that
contains the drive, and YY is the drive position inside the expansion enclosure.
• An SC200 holds up to 12 drives, which are numbered in rows starting from 0 at the top-left drive.
