Replacing Hard Drives
The SCv2000/SCv2020 storage systems support hot-swappable hard drives.
The SCv2000 storage system supports up to 12 3.5-inch hard drives installed in a four-column, three-row
configuration. The
SCv2020 storage system 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.
Dell Enterprise Plus Drives are the only drives that can be installed in an SCv2000/SCv2020 storage
system. If a non Dell Enterprise Plus Drive is installed, Storage Center prevents the drive from being
managed.
SCv2000/SCv2020 Storage System Drive Numbering
In an SCv2000/SCv2020 storage system, 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 storage
system, and YY is the drive position inside the storage system.
• An SCv2000 holds up to 12 drives, which are numbered left to right in rows starting from 0 at the top-
left drive.

• An SCv2020 holds up to 24 drives, which are numbered left to right starting from 0.
