About the SC100/SC120 Expansion
Enclosure
An SC100/SC120 expansion enclosure provides expansion storage for an SCv2000/SCv2020 storage
system.
The SC100/SC120 connects directly to the SAS ports on the back of the storage system.
SC100/SC120 Expansion Enclosure Overview
The SC100 is a 2U expansion enclosure that supports up to 12 3.5‐inch hard drives installed in a four‐
column, three-row configuration. The
SC120 is a 2U expansion enclosure that supports up to 24 2.5‐inch
hard drives installed vertically side‐by‐side.
An SC100/SC120 expansion enclosure ships with two redundant power supply/cooling fan modules and
two redundant enclosure management modules (EMMs).
SC100/SC120 Expansion Enclosure Monitoring and
Diagnostics
The Storage Center OS generates alert messages for temperature, I/O module, fan module, disk, and
power conditions for Storage Center components. Use the Dell Storage Client to view these alerts.
The SC100/SC120 also has LED indicators to notify you of a possible problem with the expansion
enclosure.
NOTE: Dell OpenManage Server Administrator is not available for the SC100/SC120.
