Replacing Hard Drives

The SC100/SC120 expansion enclosures support hot-swappable hard drives.
The SC100 expansion enclosure supports up to 12 3.5-inch hard drives installed in a four-column, three-
row configuration. The SC120 expansion enclosure supports up to 24 2.5-inch hard drives installed
vertically side-by-side. Hard drives are connected to a backplane through hard drive carriers. Hard drive
blanks are installed in the hard drive bays that are not occupied.

SC100/SC120 Expansion Enclosure Drive Numbering

In an SC100/SC120 expansion enclosure, the drives are numbered from left to right.
Dell Storage Client identifies drives as XX-YY, where XX is the number of the unit ID of the expansion
enclosure, and YY is the drive position inside the expansion enclosure.
• An SC100 holds up to 12 drives, which are numbered left to right in rows starting from 0 at the top-
left drive.
