Interconnect link types

Interconnects enable communication between the server hardware in the enclosure and the data center networks. An interconnect has several types of links:

Uplinks

Uplinks are physical ports that connect the interconnect to the data center networks.

Downlinks

Downlinks connect the interconnect to the server hardware through the enclosure midplane.

Stacking links

Stacking links, which can be internal or external, connect interconnects together to provide redundant paths for Ethernet traffic from servers to the data center networks. Stacking links are based on the configuration of the associated logical interconnect group.

FCoE traffic is not supported over stacking links.
