About logical interconnects

For more information about logical interconnects, see:

A logical interconnect is a single administrative entity that consists of the configuration for a set of interconnects in a single enclosure, and includes:

  • The uplink sets, which connect to data center networks.

  • The mapping of networks to physical uplink ports, which is defined by the uplink sets for a logical interconnect.

  • The internal networks, which are used for server-to-server communications without traffic egressing any uplinks.

  • The downlink ports, which connect through the enclosure midplane to the servers in the enclosure.

  • The connections between interconnects, which are called stacking links.

  • Stacking links can be internal cables (through the enclosure) or external cables between the external ports of interconnects.

See the appropriate support or compatibility matrix on the Hewlett Packard Enterprise Information Library for the maximum number of networks that can be provisioned on a logical interconnect.

For a server administrator, a logical interconnect represents the available networks through the interconnect uplinks and the interconnect downlink capabilities through a physical server’s interfaces. For a network administrator, a logical interconnect represents an Ethernet stacking configuration, aggregation layer connectivity, stacking topology, network reachability, statistics, and troubleshooting tools.
