4.7 (Optional) Data Switch
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 controllers when:
l The storage system is installed for the first time. For detailed connection diagrams and
configurations, see the Installation Guide corresponding to your product model.
l The storage system capacity is expanded. To expand the capacity of storage components,
contact the technical support center.
When a storage system uses a switch-connection network for capacity expansion, only some
functions of the switches are used. For more information about the switches, see the
CloudEngine 8800&7800&6800&5800 Product Documentation.
