Data Switch (CE8850-SAN)
Data switches provide a high bandwidth and low latency to connect controller enclosures for their control information exchange and service data flows. They are typically used for connections between multiple controller enclosures when:
- The storage system is installed for the first time. For detailed connection diagrams and configurations, see the Installation Guide corresponding to your product model.
- The storage system capacity is expanded. To expand the capacity of storage components, contact the technical support center.
The switches used for controller expansion can be deployed on a scale-out network only, not for front-end service networking or other purposes.
