Overview of SC220 Compellent Expansion Enclosures
The SC220 Compellent Expansion Enclosure is a Dell EMC storage solution designed to expand the storage capacity of the Dell EMC Compellent Storage Center. The SC220 enclosure is a 2U rack-mounted device that can hold up to 24 2.5-inch SAS or NL-SAS hard drives or solid-state drives, providing up to 28.8 terabytes of additional storage capacity per enclosure.
The SC220 enclosure is a modular system that allows for the hot-swapping of drives, making it easy to add or replace drives without disrupting storage operations. The enclosure is designed for use in high-density environments and supports up to six enclosures in a single Storage Center system, providing up to 172.8 terabytes of additional storage capacity.
The SC220 enclosure supports both RAID 5 and RAID 6 configurations for data protection and is compatible with both 6Gbps and 12Gbps SAS host bus adapters. The enclosure also features redundant hot-swappable power supplies and cooling fans for added reliability and uptime.
The SC220 enclosure is managed through the Dell EMC Storage Center management interface, which provides a unified view of all storage resources within the system. The management interface allows for easy configuration of the SC220 enclosure, including the creation of RAID sets, the addition or removal of drives, and the monitoring of system health and performance.

- Management interface: The SC220 enclosure is managed through the Dell EMC Storage Center management interface, which provides a unified view of all storage resources within the system. This management interface allows for easy configuration and monitoring of the SC220 enclosure, simplifying storage management tasks.
Troubleshooting Common Issues
Here are some common issues with SC220 Compellent Expansion Enclosures and their troubleshooting steps:
- Drive failure: If a drive in the SC220 enclosure fails, you can replace it with a new one. The Dell EMC Storage Center management interface will automatically begin the rebuilding process, which will restore the data from the failed drive onto the new one.
- Power supply failure: If a power supply in the SC220 enclosure fails, you can replace it with a new one. The other power supply will continue to power the enclosure while the failed power supply is being replaced.
- Cooling fan failure: If a cooling fan in the SC220 enclosure fails, you can replace it with a new one. The other cooling fans will continue to cool the enclosure while the failed fan is being replaced.
- Compatibility issues: Ensure that the SC220 enclosure is compatible with your host bus adapter (HBA) and SAS controllers. Make sure that your HBA firmware and SAS controller firmware are up to date.
- Connectivity issues: Check the SAS cables for any damage or loose connections. Ensure that the SAS cables are securely connected to the SAS controller and the SC220 enclosure.
- Drive not recognized: If a new drive is not recognized by the SC220 enclosure, check the SAS connection and ensure that the drive is properly seated in the drive bay.
- Overheating issues: Check the temperature and cooling status of the enclosure. Ensure that the enclosure has adequate airflow and that the cooling fans are functioning properly.
