Component redundancy and hot swap, hot expansion
In order to ensure reliable operation and high availability, the ETERNUS disk storage systems have a fully redundant configuration and hot maintenance capability. The interconnection of the CMs is duplicated.
A drive enclosure (DE) has also two independent interface ports that are directly connected to two CMs for path redundancy.
The use of redundant components and multiple controller-to-drive connections ensures exceptional reliability. Hardware components supporting hot swap and hot expansion features not only enable firmware upgrades during system operation, but also provide capacity expansion together with the LUN expansion feature where DEs or HDDs are added as needed.
