SC200 and SC220 Overview
A Storage Center enclosure holds the physical disks that provide storage. The interface
between the controller IO cards and the enclosure is referred to as back-end connectivity.
SC200 and SC220 Hardware
The Storage Center SC200 and SC220 are 2U size SAS enclosures. The SC200 enclosure
supports up to 12 3.5-inch hard drives installed in a four-column, three-row configuration.
The SC220 enclosure supports up to 24 2.5-inch hard drives installed vertically side-by-
side. The SC200 and SC220 enclosures ship with two power supply/cooling fan modules
and two redundant enclosure management modules (EMMs).
SC200 and SC220 Monitoring and Diagnostics
The Storage Center OS generates alert messages for temperature, IO module, fan, disk,
and power conditions for Storage Center components. Use the Storage Center System
Manager to view these alerts.
The SC200 and SC220 enclosures also have LED indicators to notify you of a possible
problem with the enclosure.
Note: Dell OpenManage Server Administrator is not available for SC200 and
SC220 enclosures.
