Single Path Connection

A single path configuration connects the ETERNUS DX to a server via a single path.

The server cannot access an ETERNUS DX when a component (such as a controller, HBA, switch, or cable) on the path has a problem. The system must be stopped when a failed component on a path needs to be replaced or when the controller firmware needs to be updated.

In a single path connection configuration, the path failover and load balancing functions are not supported.

A multipath connection configuration is recommended to maintain availability when a problem occurs.
